The controllers were supported by aisle supervisors and a systems supervisor. Fog had not been forecast for Adelaide when the crew submitted their flight plan. Mildura Observations. These conditions include thunderstorms, hail storms and fog. MATS version23 was current at the time of occurrence involving VH-YIR and VH-VYK. The Manual of Air Traffic Services (MATS) is a joint document of Airservices and the Department of Defence. This meant that flight following personnel provided relevant updates to the flight crew on weather and operational matters. Why would you not have the 5 year comparison data available for validation or comparison? The flight crew of Qantas 735 proactively sought weather information for various airports soon after departing Sydney. Mildura Weather Forecast, VIC 3500 - WillyWeather. These include increased monitoring and support as required and the potential to reduce pilot workload in stressful situations. In addition, it is not possible for an ABS to recognise the importance of, and then actively disseminate SPECI information to pilots. This resulted in the need for both Qantas 735 and Velocity 1384 to land in conditions that were below minima. In addition, improved conditions could be expected from 1000 as the wind was forecast to tend southerly and both fog and low cloud were rare in a southerly flow at Mildura. This decision was passed to the crew of Qantas 735. Water Data Online provides free access to nationally current and historical water information that is collected by the Bureau of Meteorology under the Water Regulations (2008). This includes weather and operational information for the destination, which should be considered prior to a decision point or point of no return. This claim, however, cannot be verified because the BoM uses a non-standard method for recording temperatures at Mildura, and furthermore the parallel data provided to me in December 2017 as proof of equivalence is flawed and deficient. However, once Qantas 735 commenced descent towards Mildura, the divert time of 0955 would have reduced by about 20 minutes due to the increasing distance from Adelaide and additional fuel required to climb back to cruise altitude and effect a return. Based on this information, the forecast for TEMPO conditions was continued. Daily Weather Observations are also routinely prepared for hundreds of other locations in Victoria and across Australia. This included that At any time after dispatch, it is the PICs [pilot in command] responsibility to ensure the fuel on board is sufficient to allow for the safe operation of the aircraft to an adequate aerodrome. Ltd. (Virgin). For many nonmajor airports in Australia, flight crews of arriving aircraft can access current weather information using an Automatic Weather Information Service via very high frequency radio, which has range limitations. During the forum, it was apparent that there was an expectation by pilots that they would be told of any significant deterioration in weather by ATC. Based on the procedure that any current code grey is superseded by the 1800 to 2400 UTC TAF, the TAF issued at 1800 UTC for Adelaide would normally cancel the code grey forecast. The AIP ENR 1.10 paragraph 1.1 had a requirement for a pilot in command to consider forecasts and observation reports during their pre-flight planning. At 0954, the controller made another all stations broadcast with the latest TAF issued for Mildura, valid from 1000. This service responds to in-flight requests for operational information from pilots operating in all classes of airspace on air traffic control VHF frequencies or high frequencies (HF). Also details how to interpret the radar images and information on subscribing to further enhanced radar information services available from the Bureau of Meteorology. C. In response the forecaster contacted the BoM observer located at Mildura Airport. At the time that Velocity 1384 departed Brisbane, the TAF current for their arrival into Adelaide forecast fine conditions. The BoM observer at Mildura Airport advised the forecasting office that the mist and subsequent fog arrived from the south and resulted in a rapid deterioration in conditions. Distribute short AIREPs originated by general aviation pilots to: the MET office responsible for MET watch over the area, the briefing office associated with the area. Common Traffic Advisory Frequency is the frequency on which pilots operating at a non-towered aerodrome should make positional radio broadcasts. In order to proceed to an airport with a TEMPO for deterioration of weather conditions below the alternate criteria, crews must ensure they have sufficient fuel to hold for the duration of the deterioration and land with fuel reserves intact, or provide for flight to an alternate destination. [15] Generation of a routine TAF for Mildura Airport is also secondary to issuing trend forecasts (TTF) and amended TAFs for major international airports and category A airports (such as Canberra). The section of this version on the provision of FIS to pilots in flight indicated that the controller was to provide FIS to all aircraft that were being provided with an ATC service. Velocity1384 landed at Mildura at 1014, in fog conditions. In addition, changes regarding the 60minute time period in which amended aerodrome forecast information would be broadcast to aircraft that are being provided with an ATC service, aligned the MATS to the International Civil Aviation Organization (ICAO) Regional Supplementary Procedures. The controller could request specific SPECI reports for an airport if required; however, only those SPECI reports that covered airports without an ABS would be automatically sent to the controllers workstation. Finding an ideal family-friendly small hotel in Mildura does not have to be difficult. review the distribution, dissemination and sharing of operational information to the aviation industry as stipulated by the Civil Aviation Safety Authority, and enacted by Airservices Australia and the Bureau of Meteorology. While Velocity 1384 was en route to Adelaide, and while Qantas 735 was in the process of departing for Adelaide, an updated forecast was issued at 0700 including a 30 per cent probability of fog. In addition, the ATSB noted that the industry expectation for the provision of flight information services was not aligned with that provided by Airservices Australia (Airservices). At 0948 the crew of the Dash-8 asked Qantas 735 for their assessment of the weather. Distance measuring equipment or marker beacons along the approach provide distance information. Manual checking a Mercury thermometer is not my job. After scrutiny of the A8 forms actually provided, however, it appeared that the extent of parallel readings for the probe installed on 27 June 2012 would be limited to just the eight months July 2012 to February 2013 except that the BoM had omitted to scan September 2012 the one month that could provide a direct measure of the equivalence of the relevant probe for that time of year at that location. The AIP defined hazard alerts to include: observations, pilot reports, or amended forecasts indicating that weather conditions at the destination have unexpectedly deteriorated below the IFR or VFR alternate minima, and. These included updates of forecasts and observations and occurred frequently for the remainder of the flight to waypoint BLACK (48 NM or 89 km from Adelaide). In order to provide some airline operators an advance notice about such low probability weather conditions that may interrupt flight operations, the BoM issues an aerodrome weather briefing (AWB) product and, if applicable, a code grey forecast. If not, what did they record it for? This ATCinitiated flight information service (FIS) (see the section titled Airservices Australia) extends to aircraft within 60 minutes of the condition or destination. In addition, it was possible for fog to exist at nearby locations, such as at Edinburgh Airport, without operations at Adelaide Airport being affected. It allows for completion of the ILS and autoland following failure of any single system component after a specified alert height as determined by a number of safety parameters. It also influenced the decision making of the Virgin Australia flight watch personnel, who did not pass this weather to the flight crew of Velocity 1384. The availability of SPECI from an ABS meets the requirement for in-flight information service. And they fail! AIP GEN Section 3.3.1 stated that FIS will be provided whenever practicable to all aircraft that are known to be affected by the information. 3.3.5 FIS does not diminish the responsibilities normally vested in the pilot of an aircraft, including that for making a final decision regarding any suggested alteration to flight plan. The Mallee en route sector comprised the airspace from 140 NM (259 km) to about 270 NM (500 km) to the east of Adelaide Airport and included the en route airspace above Mildura. Flight dispatch and following was similar to Virgin in that only international and selected short haul flights were actively flight followed. As a consequence, the data for this period from the mercury thermometer is not normally distributed, as shown in Figure 1. The AIP did not contain a list of information that would constitute a Hazard Alert, or what constituted non-routine meteorological products. The broadcast is usually continuous with updates available on a minute by minute basis. Alerting function of special weather reports (SPECI) is not met by the automatic broadcast services, Limited provision of flight information service for some non major airports, Information Publication Scheme - Agency Publication Plan, Human Factors for Transport Safety Investigators course, Transport Safety Investigation Regulations, Information for police and coronial officers, Railway accident guidelines for operators, Mandatory - Aviation accident or incident notification, Voluntary - REPCON Aviation Confidential Reporting Scheme, Mandatory - Marine accident or incident notification, Voluntary - REPCON Marine Confidential Reporting Scheme, Mandatory - Rail accident or incident notification, Voluntary - REPCON Rail Confidential Reporting Scheme. Aeronautical Information Publication (AIP) Australia GEN 3.3, Section 2 FLIGHT INFORMATION SERVICE contained information about the provision of a flight information service (FIS). Prior to this point, about 5 minutes after takeoff, the crew of Qantas 735 sent a request via the aircraft communications addressing and reporting system for the current Aerodrome Terminal Information Service at Adelaide Airport. A signal from an aircraft to the ground station is used to calculate its distance from the ground station. When the aircraft was at the decision altitude, the crew initiated a missed approach procedure as they had not obtained visual reference with the runway. At 0916, an air ambulance pilot who was departing Mildura Airport made a call to the Mallee sector air traffic controller, who was responsible for the airspace above Mildura. This alert is used to notify flight crew of a sudden change to a component of FIS, not described in a current MET product or NOTAM, having an immediate and detrimental effect on the safety of an aircraft. The 0800 TTF indicated fog as it was considered imminent and formed at 0804, which was reflected in a SPECI issued at 0805. The area GPS-based navigation Global Navigation Satellite System (RNAV GNSS) instrument approach to runway27 at Mildura required pilots to be clear of cloud at a minima of 660 ft (493ft AGL), reducing to 560 ft (393 ft AGL) using an actual aerodrome QNH[6] (see the sections titled Area navigation Global Positioning System navigation systemand Airport information). At around 0900, weather instrumentation at Mildura Airport started to indicate patches of low cloud around 400 ft AGL and a visual satellite image indicated a bank of low cloud south of the airport. Virgin Australia Airlines Pty. However, this service was not guaranteed and as such, the responsibility for checking the weather enroute remained with the pilot in command but may be assisted by the operators flight operations personnel in some cases. This project aims to develop a new national climatological interface for the display and interpretation of climate information at aerodromes and key aviation locations (due to be completed in 2017). Applicable to this occurrence, where the valid TAF indicated weather below landing minima at the destination, and a recent observation report indicated weather above the minima (without a trend specified, that is no TTF), CASA reported that: for in-flight planning considerations the decision making must be based on the forecast element so a pilot must hold an alternate and applicable fuel but is able to make a decision to attempt an approach at the destination should the flight crew calculate additional fuel is available to do so. The declaration of an emergency, including due to insufficient fuel, enables ATC to understand the nature and extent of the situation. Broadcast system components comprised a ground- or spacebased transmitter, an aircraft receiver and a portable or installed cockpit display device. The BoM Aeronautical Services Handbook (ASH), which is available as guidance for staff, lists the priorities for the provision of services. observations list type; observations; sky observations; Sunday January 8, 2023. choose date: local weather; observations; sky conditions; daily summaries; climate; When the aircraft touched down, the No. These findings should not be read as apportioning blame or liability to any particular organisation or individual. When the amended TAF for Adelaide Airport was issued at 0700, neither Velocity 1384 nor Qantas 735 were within 60 minutes of Adelaide. The BoM reported that the fog conditions at Adelaide were particularly unusual and that, based on their experience, they did not initially expect it to form. Given the 2-minute time period between the air ambulance pilots report of the deterioration and the production of a SPECI, the opportunity for a hazard alert to incoming aircraft was effectively negated. However, CAR 257(5) specified that if an emergency arises that, in the interests of safety, makes it necessary for an aircraft to land at an aerodrome where the meteorological minima is less than that determined for that aircraft operation at that aerodrome then CAR 257(4) did not apply. The Centralised-AWIS (C-AWIS) project aims to deliver a cost effective and reliable replacement to the current AWIB/AWIS that will centrally process AWS data. On the morning of the occurrence, the upper air wind flight at 0300 measured the 2,000 ft wind as being outside the fog formation envelope of the fog forecasting procedures. The BoM reported that their review of the forecasting used for Mildura on the day of the occurrence showed that the conditions (including wind direction) were not conducive to fog developing at that time of day and were more consistent with the possibility of low cloud. Critical to the assurance of safe flight, all elements of the aviation system including weather services, air traffic services, aircraft operators and flight crews need to have a clear understanding of their roles and responsibilities in that system. It is also worth noting that the separation workload is generally greater than normal when weather disrupts the usual flow of traffic. Airservices advised that monitoring of a flight will increase if flight crew declare an emergency. Provides access to Australian weather forecasts, weather observations, flood warnings and high sea forecasts from each state and territory provided by the Bureau of Meteorology. About 10 minutes later, the TTF was amended to forecast fog to occur before the aircraft's arrival time. Flight planning was required to take into account the requirements for holding fuel in lieu of the requirement to nominate an alternate. And I noted that some of the temperature variations were within the range of the warming attributed to global warming over the second half of the 20th century. PS The silence accorded the Bureau by the mainstream media for all of their indiscretions is much more complete than that ever accorded Barnaby Joyce. On the same morning, another B737 aircraft, registered VH-VYK and operated by Qantas Airways, was conducting a scheduled passenger service from Sydney, New South Wales, to Adelaide. Irrespective, the extent and duration of the deterioration meant that even meeting the TEMPO fuel requirement, this would not have provided sufficient fuel to hold until the fog and low cloud at Mildura cleared sufficiently. 2 main wing tank remained constant. These included the need for distance vision correction to be worn. The METAR observation reports issued for Mildura at 0830 and 0900 showed light winds, visibility in excess of 10 km and the cloud lifting from broken at 3,400 to broken at 3,900 ft. This service continuously broadcasts routine meteorological reports (METAR) on a network of VHF transmitters. There was only one occurrence found where the pilot believed they should have received greater assistance from ATC, however that occurred in the context of high controller workload and potential miscommunication between the pilot and ATC about the situation. definition of notifiable updates) and removal of the differentiation between passive and active flight following such that all flights are now flight followed. CASA responded that a pilot is able to use a valid forecast and observation information. Bureau Home > Australia > Victoria > Forecasts > Mildura Forecast. The ATSB examined the training and guidance material available to air traffic controllers relating to the provision of air traffic services. Given the prevalence of AWIS at many nonmajor airports in Australia, there remains a risk that, given this 30-minute gap in the availability of weather reports, pilots will not be made aware of significant weather deteriorations at these airports in sufficient time to support their in-flight decision making. The team leader on the day was a qualified dispatcher with over 20 years of experience. The Virgin operations manual, volume 1A, section 9.1.3 outlined the post-dispatch fuel requirements for flight crew. A number of reviews of the ATSB occurrence database were carried out in an effort to understand the potential operational and other factors in this occurrence. The flight crew of Qantas 735 asked ATC if this improvement appeared likely as forecast and, as a result, the en route controller contacted Adelaide Tower to ascertain the current conditions. Madden Avenue Service Centre108 Madden Avenue, Mildura VICAustralia Why would any bureau not use worlds best practice to measure temperatures? Centre of Australian Weather and Climate Research. It also noted that: To ensure that accurate information is obtained in adequate time, pilots must take into consideration that ATC initiated FIS is limited to aircraft within one hours flight time of the condition or destination at time of receipt of the information by ATC. However, Jeppesen Air traffic rules and services,section 8.5 ATC initiated FIS did contain this advice. Within the hour, the weather conditions deteriorated below the landing minima at Adelaide Airport due to fog. It stated that FIS was to include operational information about meteorological conditions and hazard alerts. The AIP outlines the elements of ATC-initiated FIS. In particular, if a SPECI report was available from an automatic broadcast service (ABS) then it would not be made available to the pilot by ATC. This includes river heights. As such, there is still a reliance on services such as FIS to provide pilots with an appreciation of deteriorations in weather at certain airports. Their arrival at Mildura Airport in the now deteriorated weather meant that they had insufficient fuel to divert to another airport. These requests for forecasts and observations ceased when Qantas 735 reached holding waypoint BLACK. If there is no AWIS, or it is a major airport, ATC will advise the availability of a SPECI report as FIS, workload permitting. 1 tank is integral with the left main wing, the No. On 23 September 2017, a new record hot day for Victoria was claimed at the Mildura airport using an electronic probe in an automatic weather station (AWS) housed in a Stevenson screen. While the 0700 amended TAF and 0800 TTF were not required to be sent to the crew under Virgins flight following procedures, not passing the weather removed an important source of information regarding the deteriorating conditions at Adelaide. The validity time for the actual aerodrome QNH is listed as 15 minutes from the time of receipt. The aircraft was certificated for autoland approaches, but the ground equipment was not. At the time the amended TAF was issued at 0700, Velocity 1384 was at FL 400 in the cruise, about 150 NM (278 km) from Brisbane. 9669 4082, by fax on (03) 9669 4515, or by email on climatedata@bom.gov.au We have taken all due care but cannot provide any warranty nor accept any liability for this information. The March 2009 changes to the AIP were communicated to the aviation industry by three methods. AIP GEN 3.5 Section 10.2.1 stated that to the extent possible, controllers will issue pertinent information of weather and [stipulated] areas and assist pilots in avoiding such areas if requested. As such, when the crew of Velocity 1384 initiated the diversion to Mildura Airport, they had not confirmed sufficient fuel to meet the TEMPO requirement. While the increase in data was a benefit to BoM, an unexpected outcome was the production of numerous AUTO SPECI reports. The aircraft tracked to the north-east of the aerodrome and the crew informed ATC that they would conduct an instrument landing system (ILS) approach to runway 23 and then land using the aircraft's autoland system. This data could be accessed from ATC on request, or by pilots directly via a telephone number that was provided in the NOTAM. In addition to training in core ATC competencies, controllers received training in the classroom and simulator that covered aircraft operational aspects including, but not limited to: Additionally, assessment was made in simulators and onthejob in relation to controllers management of nonroutine events. In such cases there is a residual risk that the aircraft may be compelled to land in conditions below the landing minima. This speaks volumes about their integrity and character. The amendment further indicated that the use of the prefix hazard alert was only to be used until such time as the updated meteorological product, such as a report or forecast, or NOTAM on which the alert was based, became available to pilots by other means. On 20 August 1999, as the Airbus A320 aircraft, registered VH-HYO, approached runway 23 at Adelaide Airport, South Australia for landing, the crew observed a bank of fog drifting toward the aerodrome from the north-east. The visibility then started to increase, with the first SPECI showing no fog, but with mist and overcast cloud at 100 ft being issued at 1048. Concurrently, the TTF for Adelaide showed light winds with few clouds with no significant changes expected over the forecast period. When the TTF for Adelaide was issued at 0800 and showed fog, flight watch again reviewed the situation for applicability to Velocity 1384. have the term METAR or SPECI appended to the report by the BoM before their distribution, including to ATC, via the Aeronautical Fixed Telecommunication Network. I am dragging up my old university stats to understand what you are on about. In response, in December 2008, Airservices conducted a Safety Case Assessment and Reporting Determination (SCARD), which was required whenever: changes to service levels, procedures or equipment, which will affect the performance, functional or technical specification of a system or service; and organisational changes affecting safety accountabilities. Given the nature of the emergency, this allowed the crew to land despite the low visibility conditions. 128 km Mildura 5 min Rainfalls. The priority reflects the need to create forecasts and warnings in relation to time critical activities, such as ditching reports and search and rescue activities. Qantas maintained a sterile cockpit from push back until established above 10,000 ft above mean sea level in the climb. The third method was an article in the Flight Safety Australia magazine, March-April 2009 edition. They considered this was a sufficient buffer if the fog did not clear by 0900. The 0358 amended TAF for Mildura that morning forecast light winds and scattered cloud at 3,000ft and broken cloud at 6,000 ft. AIP GEN 3.5 section 6 outlined the inflight weather broadcasts available to pilots, including weather advisory broadcasts. Anything that impacts on the provision of SPECI reports and other operational information to pilots increases the risk that pilots will not be aware of the changes at the destination in sufficient time to support in-flight planning and effective decision making. As part of that process, each organisation was asked to communicate what safety actions, if any, they had carried out or were planning to carry out in relation to each safety issue relevant to their organisation. At about 2350 WST, when the flight crew commenced descent, the aircraft passed the point where it had sufficient fuel to divert to Learmonth, Western Australia. The BoM claims that measurements from such devices are comparable to measurements from traditional mercury thermometers, which were used to measure official air temperatures at Mildura from 13 June 1889 until 1 November 1996. 2 tank 18 kg remaining, with an imbalance of 576 kg. This page was created at 00:41 on Thursday 19 January 2023 (UTC), Copyright Commonwealth of Australia 2023, Bureau of Meteorology (ABN 92 637 533 532) | CRICOS Provider 02015K | Disclaimer | Privacy | Accessibility, http://www.bom.gov.au/fwo/IDV60801/IDV60801.94693.axf, http://www.bom.gov.au/fwo/IDV60801/IDV60801.94693.json. Engine shutdown was at about 1019. BoM weather radar, satellite and synoptic charts. This was despite the fact that the AWIS was not broadcasting, as communicated in the NOTAM. The estimated time of arrival at Adelaide was 0920. accuracy of aviation meteorological products in Australia. Employed to minimise unnecessary distractions during critical phases of flight. A LOW fuel indication and/or fuel IMBAL indication would normally result in the flight crew actioning the appropriate nonnormal checklist in the aircrafts Quick Reference Handbook (QRH). In addition, the Virgin meteorologist reviewed other information sources to determine the probable impact of fog on the arrival of Velocity 1384. The forecaster then issued an amended TAF at 0952 with a 30 per cent probability of fog, visibility 500 m and broken cloud at 200 ft AGL for 2 hours. Light winds. However, appropriate meteorological data was not available at the time to support such an examination and potential safety recommendation for the widespread installation of equipment of this magnitude and complexity. The amendment also introduced the following change regarding the availability of aerodrome weather reports (METAR/SPECI): In addition, when there was a sudden change in pertinent operational information that was not described in a current meteorological product or NOTAM, and the change had an immediate and detrimental effect on the safety of an aircraft, ATC would communicate this change to pilots with the prefix Hazard Alert. The investigation is continuing and will involve: The Australian Transport Safety Bureau acknowledges the traditional owners of country throughout Australia, and their continuing connection to land, sea and community. data from an electronic probe and mercury thermometer operating side-by-side for a period of time.

The FO of Velocity 1384 was absent from the flight deck and the captain reported preparing for the approach into Adelaide at that time. In the meantime, Airservices has updated the Manual of Air Traffic Services to ensure dissemination of weather information from locations with an Automatic Weather Information Service should that service be unavailable. examination of the relevant weather observations and forecasts. Just considering the values for September, the mean difference is statistically significant at the 0.05 level of probability, and is +0.34 C, +0.27 C and +0.28 C for the years 1997, 1998 and 1999, respectively. A draft of this report was provided to the flight crews of Velocity 1384 and Qantas 735, Airservices Australia, the Bureau of Meteorology, the Civil Aviation Safety Authority, Virgin Australia AirlinesPty.
