By the time that clearance was available, the remainder of the runway was obscured by fog. At 0816, the crew of Qantas 735 received information about the current conditions at Adelaide. Finding an ideal family-friendly small hotel in Mildura does not have to be difficult. The flight crews of Velocity 1384 and Qantas 735 had insufficient fuel to divert to another airport once they arrived at Mildura. In addition, the Virgin meteorologist reviewed other information sources to determine the probable impact of fog on the arrival of Velocity 1384. visibility is the average distance that distinguishing obstacles can be seen around the aerodrome. All rights reserved. If they revised the probe design several times there must have been some records kept of how, why and where. 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. Light winds. | Legal. The broadcast is usually continuous with updates available on a minute by minute basis. Altimeter barometric pressure subscale setting to provide altimeter indication of height above mean seal level in that area. VOLMET provides meteorological information for Australian major international airports and Townsville via high frequency (HF) radio transmission. This online flood map allows you to search for your property address and gives a better indication of where floodwaters may reach. similar occurrences to that at Mildura in June 2013. encounter with unforecast weather, including VFR flight into instrument meteorological conditions. The FDR recorded a LOW FUEL QTY message for both main wing tanks at about 0955. However, this reduced their options after the unexpected need to divert from Adelaide to a suitable alternate destination. Although no safety issue was identified by the ATSB, the Bureau of Meteorology advised of the following safety action in response to this occurrence: Although the TTF and TAF are forecasts for the same aerodrome, they convey different information concerning the probability and timing of meteorological phenomena. While the BoM has never released reports with parallel data supporting the claim of equivalence, in late October and early December 2017 a first and second lot of A8 forms were released to me this followed my request to Minister Josh Freydenberg on 26 September for parallel measurements, and more specifically on 22 October for these A8 forms immediately after I was informed by a whistle-blower that these forms contained the relevant information. On the day of the A320 occurrence, moisture levels were higher to the north of Adelaide, with fog forming at Edinburgh at 0730. This service was structured to support the responsibility of pilots to obtain information inflight on which to base operational decisions relating to the continuation or diversion of a flight.. A review of the relevant ATC recorded radio communication identified that the first opportunity was at 0816, when the crew of Qantas 735 requested further information from ATC regarding conditions in Adelaide. Section 1.1.2 of the Transport Canada manual was titled Flight Advisory and Information Services and outlined the elements of the in-flight information service. promulgated low visibility procedures for the conduct of CAT III ILS approaches. 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. Ltd. as Velocity 1384 and VH-VYK operated by Qantas Airways Ltd. as Qantas 735, were on scheduled flights to Adelaide, South Australia. The report on the Review of the Trend Forecast was released for comment on the 29September2015. **** The diversion of two 737 aircraft to an alternate airport due to inclement weather at the intended destination did not result in increased monitoring by ATC. They are not at the same site [about 2 klm apart] so it will be no comparison anyway but when they have this valuable historical data, why destroy it? As a consequence, the data for this period from the mercury thermometer is not normally distributed, as shown in Figure 1. 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. It stated that controllers were to consult a number of sources of information to assess if a hazard alert was necessary. C. In fact, Table 1 shows that for the last month of available parallel measurements the electronic probe (Tmax-Probe) often recorded considerably warmer than the mercury thermometer (Tmax-LIG). Why would you not have the 5 year comparison data available for validation or comparison? Forecast issued at 5:30 am EDT on Thursday 19 January 2023. Nothing in these instructions shall preclude officers from exercising their best judgement and initiative to assist pilots. provision of information to flight crews from Air traffic services (ATS), ATS policies and procedures affecting the flights, provision by the operators of information to the respective flight crews, the basis for the sequencing of the aircraft landings at Mildura, Bureau of Meteorology meteorological services and products as they applied to these flights. 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. An ATIS provides normal operational information for the airport terminal area. IDCJDW3051.202211Prepared at 16:01 UTC on Monday 16 January 2023. By providing SPECI information proactively, the risk of it being missed as a function of pilot workload, or limitations in the range of AWIS, is reduced. 256 km Mildura Radar Loop Provides access to meteorological images of the Australian weather watch radar of rainfall and wind. Readers are cautioned that new evidence will become available as the investigation progresses that will enhance the ATSB's understanding of the accident as outlined in this web update. Time: 1011 EST Velocity 1384 on final approach to runway 27 Mildura, lands at 1014 EST. - Digits on tank(s) with low fuel quantity turn amber. 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. 2 tank were selected back to ON, with the crossfeed valve open. The BoM reported that the fog forecasting procedure for Adelaide Airport used various inputs, including a computer model, observed wind speed and direction at 2,000 ft, surface wind speed, recent precipitation, dew point depression, the position of high pressure systems, and dew point as a function of time of year. The B737-800 is equipped with three fuel tanks. Despite this, it was still providing data to the BoM that was generated by the Mildura Automatic Weather Station. Mildura - Victoria. In relation to a change in weather conditions after DPA, the manual contained the following note: It is recognised that there are occasions when a flight may pass DPA with the required fuel on board and a subsequent deterioration in forecast weather may then result in the minimum mandatory requirements above not being met. This guidance identified the need to take into account the traffic and weather conditions expected for the destination, along the diversion route and at the alternate (if applicable). This arrangement is consistent with the service provided by Airservices. However, it is also worth noting that the on-request service is workload dependent, and is therefore not guaranteed. An AWIS is a transmission of actual weather conditions, as measured by automatic weather stations (AWS),[25] via either telephone or radio broadcast from selected sites. This occurrence has highlighted the effect of various factors coming together to create and influence a rare event. Indeed, while it would seem reasonable to assume that there would be dozens of reports detailing the results from such parallel studies none have been made publicly available. Location. In this instance, the controller did not pass the AIREP to incoming aircraft nor to their supervisor, who could have informed BoM of the deterioration. 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. A Notice To Airmen advises personnel concerned with flight operations of information concerning the establishment, condition or change in any aeronautical facility, service, procedure, or hazard, the timely knowledge of which is essential for safe flight. The crew attempted two ILS approaches before using autoland to land on runway 21 in weather conditions that were below the prescribed landing minima for the ILS. At about 0951 the fuel imbalance reached a maximum of 573 kg, before reducing as the fuel quantity in the No. This imbalance was likely the result of the crossfeed valve being opened by the crew. Primarily this will be achieved through the on-request service, supplemented by the ATC-initiated FIS when possible. By this time, the flight crew had gathered the latest information about the conditions at Adelaide from multiple sources, which continued to state a forecast improvement from 0900. 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. In the case of short haul domestic operations, the flight watch service was typically limited to flights from the east to the west coast of Australia, to remote islands and in support of extended diversion time operations. Fuel required to enable the aircraft to fly from that point to 1500 ft above an adequate aerodrome, make an approach and land; and, Variable Reserve based on the point above but not more than the Maximum Variable Reserve; and, Fuel to provide for WX [weather] holding, if the weather at the selected adequate aerodrome is forecast to be below the applicable alternate minima or a probability of thunderstorms is forecast; and, Fuel to provide for any required TFC [traffic] holding at the selected adequate aerodrome; and. METAR/SPECI are observations, not forecasts, and as such cannot be used for Flight Planning purposes, other than as a reference to determine temperature for performance purposes. Forecast Areas Map Observations Melbourne Observations All Victorian Observations Rainfall & River Conditions QLD QLD Weather & Warnings Warnings Summary Forecasts Brisbane Forecast Qld. In May 2012, Airservices Australia (Airservices) published on its website an information paper for pilots about the provision of in-flight information services. As the TAF had a 30 per cent chance of fog and the TTF issued at the same time forecast no deterioration, they elected not to pass the amended TAF to the crew of Velocity1384through ACARS. 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. For example, a report showing an improvement in the weather may be useful to an aircraft in the holding pattern directly overhead the aerodrome, to decide on whether or not to fly the approach or not. Notwithstanding this industry view, there is a requirement for pilots to obtain all relevant weather information inflight to aid operational decision making. A number of other aircraft, in addition to the B737, returned to their departure airports or diverted to alternate airports as a result of the reduced visibility at Adelaide Airport. 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. Mildura, Victoria November 2022 Daily Weather Observations IDCJDW3051.202211 Prepared at 13:01 UTC on Friday 2 December 2022 Source of data Observations were drawn from Mildura Airport {station 076031}. 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. As such, they were not required to carry fuel to reach an alternate. As such, no analysis or findings are included in this report. In respect of the provision of SPECI information to pilots, MATS was amended to include the requirement that: Do not alert pilots to the availability of a SPECI that can be obtained from an Automatic Broadcast Service. On being informed by ATC that the latest trend forecast for Adelaide predicted a delay in the fog clearing of 30 minutes, and after gathering observation reports for Mildura, the crew of Qantas735also elected to divert there at 0913. This data could be accessed from ATC on request, or by pilots directly via a telephone number that was provided in the NOTAM. 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. You do not have a default location set 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. In terms of their in-flight decision making, it is reasonable to expect that such requests would occur prior to a decision point or point of no return. The blue shaded area represents what hydrologists estimate the extent of the floods may be based on historical information captured (for example: photos and gauge heights). In addressing those issues, the ATSB prefers to encourage relevant organisation(s) to proactively initiate safety action, rather than to issue formal safety recommendations or safety advisory notices. For further information on the history of the changes to FIS and hazard alerting, see appendix D. The AIP GEN 3.5 section 11 contained information for pilots in relation to broadcasting an air report (AIREP). We pay our respects to them and their cultures, and to elders both past and present. 1968 Total Observations 10% 20% 30% Calm 3% . - Displayed until quantity is increased to 1,134 kg (2,500 lbs). The Bureau of Meteorology advised of various system changes and improvements in response to this occurrence. The BoM advised the NOC that conditions were unlikely to improve in the next 15 minutes. In order to use Mildura Airport as an alternate, the forecast cloud and visibility were required to be above the alternate minima. At about 1015 EST on 18 June 2013 air traffic control advised the ATSB of a fuel related occurrence involving a Boeing 737-8FE (B737), registered VH-YIR, at Mildura Airport, Victoria. The BOM are employing clowns? However, it is often not practical to provide for a further alternate once a diversion has been initiated. The information in amendment 58 was current at the time of the occurrence involving VHYIR and VHVYK. The ATSB also found that in certain weather patterns and at certain locations, fog is both rare and difficult to forecast reliably. The BoM simply ignores the issues that have been literally documented. In this occurrence, the forecast extension of the fog at Adelaide occurred after DPA, which limited the available options. The BoM Aeronautical Services Handbook (ASH), which is available as guidance for staff, lists the priorities for the provision of services. The meteorological information obtained from an Aerodrome Weather Information Service (AWIS) is operationally equivalent to that provided in routine (METAR)/special weather (SPECI) reports. The submissions were reviewed and where considered appropriate, the text of the report was amended accordingly. These included a low bank of cloud coming across the field, with a base of 400 ft. They were provided with two routine (METAR) reports for Mildura, which indicated conditions were suitable for an approach, with cloud above the landing minima and visibility in excess of 10 km. MILDURA AIRPORT . The BoM reported that their assessment of Mildura at around 0830 showed that low cloud was more likely to occur than fog. Qantas maintained a sterile cockpit from push back until established above 10,000 ft above mean sea level in the climb. It is a bit hard to fathom. The section relating to the provision of FIS was substantially the same as version 7 of the MATS. For regional airports, such as Mildura, the BoM relied on satellite imagery, in addition to other data, to provide indications of fog. After issuing the 0952 amended TAF, the BoM received a call about the weather at Mildura from the BoM meteorologist located at the Airservices national operations centre. On this basis, and the additional information gathered by the meteorologist, flight operations did not pass the 0800TTF to the crew of Velocity 1384. At 0940 the crew of Qantas 735 contacted Velocity 1384 to advise that they were commencing the RNAV GNSS approach due fuel. The visibility then fluctuated before dropping below 1,000 m at 0947. The aircraft was due at Perth at 0020 WST so in accordance with the operator's fuel policy, fuel was not specifically carried for a diversion to an alternate aerodrome. 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. It defined a hazard alert as information assessed by ATC to be of an unexpected and critical nature. A review of recorded radio communication between Qantas 735 and ATC identified that this frequency was also being monitored by the crew of Velocity1384 at this time. Close menu. 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. 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. These included the following products: US AIP GEN 3.5 section 7 described two basic types of FIS, broadcast only, which was called FIS-B and two-way request/reply. To supplement the information already provided, the crew asked ATC for the latest observation reports for Mildura. 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. 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). It is also worth noting that the separation workload is generally greater than normal when weather disrupts the usual flow of traffic. While the BoM had additional sources from which to obtain information about the developing deterioration at Mildura Airport, including an on-site observer, this may not be the case for all airports. In response to this occurrence, the ATSB also initiated research into the reliability of weather forecasts in Australia, initially at Adelaide and Mildura Airports (see the section ATSB research investigation). The No. This included the 0800 TTF, which indicated fog that was predicted to clear at 0900. At the time Qantas 735 made this request, the flight crew of Velocity 1384 was on the same frequency, but remained unaware of the fog in Adelaide until they were alerted by the Tailem Bend controller. On 18 June 2013, two Boeing 737 aircraft, VH-YIR operated by Virgin Australia Airlines Pty. Virgin Australia Airlines Pty. At that stage, the No. So why are they doing the parallel observations? The supervisors were also aware that the weather was similarly deteriorating and, in some cases, additional traffic holding requirements were affecting other ports such as Melbourne, Canberra and Albury. Despite the Bureau of Meteorology (BoM) knowing of the deteriorating weather at Mildura from other sources, by not passing on the in-flight weather report of deteriorating weather from the departing air ambulance pilot, the controller removed an important source of information for use by the BoM. Where is the data and analysis for these sites? Given that at 0800 neither aircraft was within 60 minutes flight time of Adelaide, a potential misinterpretation of FIS by industry was indicated. 2 tank being selected OFF, leaving the No. The crew of Qantas 735 applied a revised minimum to the approach that was 200 ft lower than that published. The content of MATS is intended to be consistent with the content of the AIP so that procedures and practices used by pilots and air traffic controllers are standardised. For those interested in checking out popular landmarks while visiting Mildura, Kar-Rama Motor Inn is . Automatic Terminal Information Service (ATIS). In particular, the sections on hazard alerts were amended, with other sections relating to the provision of significant information and a hazard alert service, and the associated responsibilities, being deleted from the manual. For the 3 days preceding the occurrence, they advised going to bed by 2000. At 0948 the crew of the Dash-8 asked Qantas 735 for their assessment of the weather. This meant that Qantas 735 continued to Adelaide with the expectation that the fog would clear prior to their arrival, which did not occur. As such, there was no requirement for the crews of Velocity 1384 or Qantas 735 to obtain or account for a code grey forecast in their fuel planning for Adelaide. Copyright 2014 - 2022 Jennifer Marohasy. The captain had also held Training Captain/Approved Testing Officer approvals since April 2003. Common Traffic Advisory Frequency is the frequency on which pilots operating at a non-towered aerodrome should make positional radio broadcasts. In relation to the provision of ATC-initiated FIS at Mildura, the controller responsible for the Mallee en route sector reported that workload initially precluded them from passing information on the weather deterioration at Mildura Airport. The United States (US) AIP that was current at the time of the occurrence listed the various areas of FIS that were provided to pilots in the US. About 5 minutes after take-off, the crew sent a request through ACARS for the current Automatic Terminal Information Service (ATIS)[21] at Adelaide. Light winds becoming west to southwesterly 15 to 20 km/h during the day. For the 201516 financial year [FY] the BoM will install weather cameras at 1520 locations at major capital city aerodromes, including Adelaide airport, and key regional aerodromes. Under Part 4, Division 2 (Investigation Reports), Section 26 of the Transport Safety Investigation Act 2003 (the Act), the ATSB may provide a draft report, on a confidential basis, to any person whom the ATSB considers appropriate. In addition, CASA clarified that there was no strategic difference between an in-flight scenario and a pre-flight plan in relation to the use of forecasts. The FO reported a duty day on 16 June 2013 that included flying BrisbaneMelbourne and return with approximately 7 hours duty time. The FOs relevant aeronautical experience is outlined in Table 4. A new routine TAF was issued for Mildura at 0902 that was valid from 1000. The crew of Velocity 1384 reported using the observation reports to confirm their understanding of Milduras suitability as an alternate destination. The MATS also outlined the responsibility of air traffic service officers in relation to how information was to be communicated to relevant aircraft. This limited their options and the time available to plan a diversion to a suitable alternate airport. For in-flight FIS, the service consisted of three elements: ATC-initiated FIS allowed for the provision to crews by ATC of pertinent operational information. Magnificent inventory management Accounts Hosted lets you record, track and reconcile everything you buy and sell. Good girl Jennifer. 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. The BoM reported that their assessment of Mildura Airport at around 0830 showed that low cloud was more likely than fog, and that improved conditions could be expected from 1000. A number of these challenges have been identified by the Centre of Australian Weather and Climate Research and include that: At interview, the BoM similarly stated that as fog is a very rare event for most airports, it is difficult to accurately forecast. Ultimately the responsibility for collecting information, such as weather updates, to support in-flight decision making remains with the pilot in command. The captain reported hearing this transmission while preparing for the approach into Adelaide. In other words, considering the forecasts that did not predict conditions below the alternate minima (0.09 per cent), and all observations below the landing minima (0.99 per cent), in the period 20092013, 10 per cent of the time that the observations were below the landing minima at Mildura Airport, those conditions were not forecast (0.09/0.99). The second was the issue of an Aeronautical Information Circular, effective 12 March 2009 that was intended to provide education on changes to the delivery of the SPECI and ARFOR elements of the ATC initiated Flight Information Service (FIS). This information is sourced from the airports AWS and is generally broadcast continuously and updated every minute. a 'live' flight plan), the TTF shall be used in the first instance, providing the flight's scheduled ETA [estimated time of arrival] is within the validity time of the TTF. The Airservices investigation into this occurrence noted that the Mallee controller did not consider the air ambulance pilots report significantly different to the forecast TEMPO conditions in the 0158TAF for Mildura. Post:PO Box 105 Mildura VIC 3502Australia, Deakin Avenue Service Centre These were triggered by a change in one of the recorded parameters meeting the requirements for a SPECI (see the section titled Automatic weather station). You should read the important information in these notes. AIRMETs (advisories of significant weather phenomena), the number of unforecast weather occurrences reported since the changes to the provision of FIS in Australia were introduced in 2009, the level of assistance provided by ATC to flight crew in response to a number of nonroutine events. It uses a number of automatic flight control systems on board the aircraft, combined with specific ground-based instrument landing system (ILS)[13] and runway environment requirements (Table 6).
