In addition, both had a flight following (flight watch) service for long haul operations (typically international) and limited following for short haul domestic operations. The CVR recorded discussion between the crew about the position of the fuel pumps and crossfeed valve. **** They are typically used in long haul operations due to the extended flight time between departure and arrival. Twenty of those years were as duty manager. Pilots can ask ATC for any relevant weather information via the onrequest service. At this time the aircraft was about 156 NM (289 km) to the east-north-east of Adelaide Airport. The availability of SPECI from an ABS meets the requirement for in-flight information service. Until late last year when as a consequence of my badgering Minister Frydenberg, backup by Alan Jones on radio 2GB and then a whistleblower telling me to ask for the A8 forms, we now finally have access to some parallel data for Mildura. Given the sleep obtained and rest opportunities available, it is not considered likely that FO fatigue was a factor in the occurrence. In assessing the magnitude of the change, Airservices identified a potential failure of the pilot does not obtain in-flight information, with the effect that the pilot is not aware of significant weather information. As a result, neither crew was required to carry additional fuel to that calculated for the flight to Adelaide, which included the mandatory fuel reserves. The ATSB identified that both flight crew uploaded sufficient fuel for the originally-forecast conditions in accordance with their operators fuel policy and the Civil Aviation Safety Authority requirements. IDCJDW3051.202211Prepared at 16:01 UTC on Monday 16 January 2023. As their planned arrival time was 0917, the crew elected to continue to Adelaide. AIP GEN3.3 section 2.5.2 stated that: When providing FIS, ATC will not alert pilots to the availability of aerodrome weather reports that are available from an automatic broadcast service. 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). The manual contains the rules that relate to the provision of air traffic services. The FO held an Air Transport Pilot (Aeroplane) Licence with a Boeing 737-300 to -900 endorsement and a current Class 1 Aviation Medical Certificate with no restrictions. A Boeing 737 aircraft had been able to land on runway 05 following a VOR/DME approach, so the A320 crew attempted to conduct a similar approach. 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. If an ABS is not available, pilots may request weather information from ATS as part of the on-request flight information service. As such, both crews were able to land under the provisions of CAR 257(5). The trend was for visibility to decrease to 500 m in fog before clearing at 0900to a visibility in excess of 10 km and few cloud. The controller then offered to gather further information for the crew of Qantas735but indicated there would be a slight delay in doing so. However, the calculation techniques and reporting frequency are different. During the period prior to the occurrence involving VH-YIR and VH-VYK, there were several amendments to the AIP regarding the provision of FIS. Other sections of the information paper repeated the information that was contained in the AIP. As with the broadcast of weather observations via ATIS, an AWIS does not append the words METAR or SPECI to weather observations that are broadcast via AWIS. 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. Nevertheless, the underpinning principle that the primary function of ATS is the safe separation of aircraft, with weather avoidance as an additional service subject to workload, is consistent with the system in Australia. 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. This predicted clearing time was also used by the flight following personnel at Virgin to inform their decision not to pass the 0800 TTF to the crew of Velocity 1384. 76 Deakin Avenue, Mildura VIC Australia 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. At about 0951 the fuel imbalance reached a maximum of 573 kg, before reducing as the fuel quantity in the No. However, it is also worth noting that the on-request service is workload dependent, and is therefore not guaranteed. The operational information required to be provided by ATC to pilots was amended to require the provision of information about meteorological conditions and the existence of non-routine meteorological products such as SPECI reports and amended TAFs. In certain conditions, provision for flight to an alternate airport will be required.

Light winds becoming southeasterly 15 to 20 km/h in the morning then becoming light in the middle of the day. The action by the crew of Qantas 735 at 0816 to seek additional information from ATC in relation to the clearance of the fog at Adelaide was to inform their decision-making as they approached the DPA. Boeing 737-800 aircraft were unable to use Broken Hill due to runway pavement limitations. Orasanu, JM 1993, Decision-making in the cockpit, in EL Wiener, BG Kanki & RL Helmreich (Eds.) Alternate fuel is calculated as sufficient fuel to approach the destination, conduct a missed approach and proceed to the nominated alternate airport for landing. During the missed approach, the crew noticed that the threshold area of runway 05 was clear and requested an immediate visual approach to runway 05 before the fog drifted further to the southwest. At 0952, Velocity 1384 updated ATC that they were still holding due to the low cloud at Mildura. This included that a special AIREP should be made when requested, or as soon as practicable after encountering a condition which is likely to affect the safety or markedly affect the efficiency of other aircraft. In this occurrence, the forecast extension of the fog at Adelaide occurred after DPA, which limited the available options. The first SPECI indicating the presence of fog was issued at 0948, showing visibility as 900 m in fog and cloud overcast at 100 ft. Note that the approved BoM observer input is optional and, if not actioned, will result in an AUTO METAR or SPECI. Consequently, the aircraft did not carry fuel for holding at Adelaide or for diversion to an alternate airport. In this case, pilots can still access the source weather data from the AWIS, although there is no verbalisation in the respective weather observations of the trigger term SPECI. To supplement the information already provided, the crew asked ATC for the latest observation reports for Mildura. The crew of Velocity 1384 were unaware of the fog and from this point commenced collecting further information and planning their diversion to Mildura. The airport runway has the capability to handle aircraft such as the . 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. Really? In addition, Virgins pilot weather requirements have been clarified and enhanced. Prior to this flight, the captain was on stand-by on 17June 2013 without being called out and had a rostered day off on 16 June 2013. The PF does most of the flying, except in defined circumstances; such as planning for descent, approach and landing. It is important that pilots understand what will be provided under Airservices provision of flight information service and that they are also able to request weather and operational information from air traffic control. Somewhat surprisingly, the automatic weather stations at Mildura for these three Septembers recorded statistically significantly cooler temperatures than the mercury thermometers. In May 2012, Airservices Australia (Airservices) published on its website an information paper for pilots about the provision of in-flight information services. This encapsulated the pre2009 FIS change through to the occurrence at Mildura. However, the accuracy of the on-board equipment meant that Qantas 735 and Velocity 1384 were aligned with the runway centre-line during the final part of their respective approaches. I have watched Peter Ridd on Sky and his revelations are very troubling but, to me, unsurprising. 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. As the Mildura AWIS was not broadcasting, application of the lower minima could only be applied if the actual QNH was obtained from ATC. This was the approach conducted by both Velocity 1384 and Qantas 735. 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. The manual gave the following guidance to crew in order to ensure compliance: Once airborne, the amount of fuel onboard the aircraft at any point inflight should not be less than: In relation to in-flight fuel checks, it further stated: If sufficient fuel does not remain on board at the PNR [Point of No Return] to allow continued flight to the destination in accordance with the inflight fuel requirements, a diversion shall be made to an aerodrome which satisfies the inflight fuel requirements. The initial public version of these safety issues and actions are repeated separately on the ATSB website to facilitate monitoring by interested parties. Ltd. as Velocity 1384 and VH-VYK operated by Qantas Airways Ltd. as Qantas 735, were on scheduled passenger flights to Adelaide, South Australia. The implementation of the next generations of TAF verification, AVS2, aims to: Climatology Interface Development Project. Qantas 735 departed Sydney, New South Wales at 0727 and had six crew and 146 passengers on board. The meteorological conditions at Adelaide Airport deteriorated below the landing minima while Velocity 1384 and Qantas 735 were en route to Adelaide. #5 of 11 B&Bs / Inns in Mildura. The flight plan provided to the crew of Velocity 1384 included the weather and NOTAMs for Mildura, as Mildura was listed as a diversion port in the event of an en route depressurisation. If the ETA is outside the validity of the TTF, then the weather requirements shall be determined from the current TAF. 0. This includes available information regarding nominated alternate aerodromes and unattended aerodromes enroute at which a landing is planned. This resulted in enhancements to Virgins flight planning and flight following policies, re-organisation of the flight following section and expansion of communication infrastructure across the Virgin fleet. Engine shutdown was at about 1019. You should read the important information in these notes. 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. Their arrival at Mildura Airport in the now deteriorated weather meant that they had insufficient fuel to divert to another airport. TCZMONTH Page 1. Of the 160 occurrences, 36 resulted in the declaration of a PAN or other emergency by the crew to facilitate either a diversion (particularly to a military airport) or priority landing. Whether or not the ATSB identifies safety issues in the course of an investigation, relevant organisations may proactively initiate safety action in order to reduce their safety risk. Additionally, the AWB for Adelaide included the potential for fog by way of a code grey, but the TAF issued at 1800 did not forecast fog. As a result of stakeholder input during the report review process, the ATSB considered the potential safety benefit of the installation of CATIII B autoland facilities at all Australian major airports. Copyright 2014 - 2022 Jennifer Marohasy. This information will include data concerning unfavourable flight conditions and other known hazards; which may not have been available to the pilot prior to takeoff or which may have developed along the route of flight. Slight chance of a shower. This research investigation will initially examine the reliability of the aerodrome forecasts for Mildura and Adelaide Airports, before expanding to cover other major Australian airports. Automatic weather stations (AWS) provide data to the BoM that is used to generate observation reports and forecasts at various locations throughout Australia. Highreliability industries are characterised by highconsequence but very low likelihood of an adverse outcome. These services did not provide for the recognition and active dissemination of special weather reports (SPECI) to pilots, thereby not meeting the intent of the SPECI alerting function provided by controller-initiated flight information service. Fog had not been forecast for Adelaide when the crew submitted their flight plan. The day previously (17 June 2013), the FO was on stand-by without being called out. They also cautioned that observations should only be used if the arrival time was proximal to the observation and, if the forecast indicated conditions below minima, the forecast would have precedence over observations. 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. 2 tank supplying the majority of the fuel to both engines and therefore being used at a higher rate. Due to limited information, the ATSB was not able to validate the crew of Qantas 735s calculations. definition of notifiable updates) and removal of the differentiation between passive and active flight following such that all flights are now flight followed. As such, they were not required to carry fuel to reach an alternate. Oh dear Dr Marohasy, BoM must be triggered by this post: https://thewest.com.au/news/weather/bureau-of-meteorology-staff-step-up-industrial-action-ng-b88757610z. Also details how to interpret the radar images and information on subscribing to further enhanced radar information services available from the Bureau of Meteorology. It was also noted at the forum that, while ACARS equipment is widely fitted and used on large jet aircraft, not all Australian airline fleets are equipped with ACARS. Madden Avenue Service Centre108 Madden Avenue, Mildura VICAustralia The distance at which flight crew can access the relevant AWIS is limited by the range of VHF but is typically within about 30 minutes flight time for large jet aircraft at normal cruising altitudes. This decision took into account the observations at Mildura, which indicated the weather there was suitable for landing. At 1002, Velocity 1384 transmitted that they were on a 4 NM (7 km) final for the RNAV GNSS approach. In support of this decision, the flight following personnel understood that as this flight was not being actively flight followed, the flight crew would, as part of their normal responsibilities, be actioning any weather updates. In addition, a notice to airmen (NOTAM)[14] listed holding requirements for Melbourne. Weather Wind Rainfall Sun Moon UV Tides Swell. The chance of a thunderstorm, possibly severe. The reviews, and subsequent procedural amendments, resulted in a number of changes in the way in which SPECI reports were handled by the air traffic control system and the way in which this information was relayed to pilots in flight. This included amendments to meteorological products such as: The provision of this service is limited to aircraft within 1 hours flight time of the condition or destination, or 2 hours for a SIGMET. Virgin advised that a review of their operations identified no systemic issue in relation to flight crew seeking weather information. A trend forecast is defined as an aerodrome weather report to which a statement of trend is appended. The captain reported their recent sleep as normal. Given the nature of the emergency, this allowed the crew to land despite the low visibility conditions. AWIS allows for the actual weather conditions at suitably-equipped locations to be accessed by telephone and, at some locations, the information is also broadcast on VHF. Finding an ideal family-friendly small hotel in Mildura does not have to be difficult. This map will be updated as more accurate modelling becomes available. The ATSB commenced an investigation at about 1100 on 18 June 2013 and the cockpit voice recorder and flight data recorder were removed from the aircraft and forwarded to the ATSBs facilities in Canberra for download. In order to better quantify the residual risk, specifically the likelihood of unforecast weather deterioration, the ATSB is examining the reliability of aerodrome forecasts as part of research investigation AR-2013-200 Reliability of aviation weather forecasts.
