bom mildura observations

The result of these reviews was reflected in changes to the AIP and to MATS in March 2009. The 0303 TAF for Adelaide on the morning of the occurrence forecast scattered cloud and light winds. Employed to minimise unnecessary distractions during critical phases of flight. Note: A Suitable Airport may be, in order of priority: an Alternate Airport, following an approach and missed approach at destination, if the destination requires an alternate; or. In addition, the section relating to the responsibilities of officers exercising their best judgement and initiative to assist pilots was removed from the section relating to the provision of flight information services. 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. 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. In my neck of the woods the BoM seem to be in the throes of replacing a long term, human attended, mercury thermometer and weather station with an AWS. Also details how to interpret the radar images and information on subscribing to further enhanced radar information services available from the Bureau of Meteorology. This service continuously broadcasts routine meteorological reports (METAR) on a network of VHF transmitters. With 1,500 kg of fuel remaining, the aircraft landed without incident in the fog with 250350 m visibility. This query was made on the same frequency as was being monitored by Velocity 1384 at the time. The BoM simply ignores the issues that have been literally documented. It also indicated that the FIS was for the provision of operational information, which included meteorological products and the existence of non-routine MET products. As a result, the crew then diverted to and landed at Wiluna. The aircraft was refuelled and the flight returned to Darlot once conditions improved. At 0844, when Velocity 1384 and Qantas 735 were both on the Tailem Bend sector frequency, the controller provided the following information: Qantas seven-thirty-five and Velocity thirteen-eighty-four you are probably both aware of the weather in Adelaide at the moment. At 0820, the aircraft reached its latest point of safe diversion back to Sydney. Sunny. On the same morning, another B737 aircraft, registered VH-VYK and operated by Qantas Airways Limited, was conducting a scheduled passenger service from Sydney, New South Wales, to Adelaide. The controller then offered to gather further information and get back to the flight crew of Qantas 735 but indicated there would be a slight delay. There is the potential that due to workload considerations, pilot requests may be redirected to another VHF frequency or Flightwatch HF. Both allowed aircraft to be dispatched without carrying alternate fuel if the weather forecast for the destination did not require an alternate. 2 tank were selected back to ON, with the crossfeed valve open. When opened, a cross-feed valve located in the centre tank and controlled by a switch on the cockpit forward overhead panel allows both engines to be supplied from one wing tank. At the time of release of this report, the BoM was progressing the action items from the report and will discuss the outcomes with CASA. An autoland is a precise, repeatable landing that can be conducted in poor weather conditions where insufficient visual cues are available to the pilots. The 0954 amended TAF was passed to Mildura traffic by the Mallee controller once it was released by the BoM. 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). Light winds becoming easterly 15 to 20 km/h during the day then becoming light during the afternoon. 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}. It is a bit hard to fathom. 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). MATS version7, effective on 11 March 2009, amended the examples of non-routine meteorological products to selected SPECI reports under the Scope of FIS section. Short haul domestic operations, particularly those under 90 minutes duration, were provided with updated weather and operational information on a workload permitting basis. Readers are cautioned that there is the possibility that new evidence may become available that alters the circumstances as depicted in the report. At 1014, Velocity 1384 landed at Mildura in foggy conditions with fuel below the required reserves. This map will be updated as more accurate modelling becomes available. visibility is the average distance that distinguishing obstacles can be seen around the aerodrome. At 1004, as they were not visual with the runway, the crew initiated a missed approach from 132ftAGL. They then continued to collect weather updates for various ports, including Mildura, Melbourne, Canberra, Sydney and Adelaide. READ MORE. This comprised flight fuel to Adelaide of 5,000 kg, variable and fixed fuel reserves of 1,600 kg and additional fuel of 1,300 kg. Automatic En Route Information Service (AERIS), Aerodrome Weather Information Service (AWIS), and. The ATSBs ongoing investigation will examine the: The information contained in this preliminary report is derived from the initial investigation of the occurrence. These reports: The on-request service is available to all aircraft in all classes of airspace on VHF or HF. The dispatch duty manager had oversight of the dispatch and flight watch functions at Qantas Airways Ltd. (Qantas). As a result of its increased understanding of events, the ATSB has expanded the scope of its investigation to examine both of these diversions and their broader context. Specifically, this included responding to changing conditions, passing operational information and responding to pilot requests. Flight dispatch and flight following consisted of two modes. Ltd. and Qantas Airways Ltd. This was the approach conducted by both Velocity 1384 and Qantas 735. 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. Keep at the BoM They need to understand that the comparison between technologies for temperature measurement are necessary public knowledge. At 0918, a special weather report (SPECI) observation was issued for Mildura, listing the cloud as broken at 200 ft, and visibility in excess of 10 km. The latest weather forecast is available at www.bom.gov.au/nsw/forecasts. The Mallee controller acknowledged the report but, at that stage neither Velocity 1384 nor Qantas 735 were on the Mallee frequency. set your location 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. However, on the day the fog did not clear as anticipated, which resulted in the forecast end period for the fog being inaccurate. 1 tank to supply both engines. This was the case for Adelaide Airport, which is affected by fog about four or five times a year. This information included the current TAF at the time the crew diverted to Mildura, which forecast a TEMPO period of low cloud covering their planned arrival time. The last 14 months of Daily Weather Observations for Mildura, Victoria are also here on this web site: Jan23Dec22Nov22Oct22Sep22Aug22Jul22Jun22May22Apr22Mar22Feb22Jan22Dec21. The AIP indicated that a hazard alert would be broadcast on appropriate ATC frequencies during the 60-minute period following the onset of the hazardous conditions, or would be directed to those aircraft in continuous communications with ATC within 60 minutes flight time of the hazardous condition. 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. the potential consequences of an unforecast fog are high. As a result, the ATSB sought clarification from CASA on the extent to which pilots are able to use observation reports for in-flight planning decisions, such as to continue to the destination or initiate a diversion. This contingency in the case of an emergency was permitted under Civil Aviation Regulation 257(5). However, as the Mildura AWIS was not broadcasting the actual weather conditions, which were consistent with the SPECI, it could be considered that ATC should have provided this SPECI information to incoming aircraft as ATC-initiated FIS. Jennifer, you have raised an extremely important point here about side by side verification testing, I wonder if any of the other bureau have the data? If you are using these pages, you are deemed to have understood the important information in these notes. The arrival time of Velocity 1384 was planned for 0920, which was after the forecast clearance of the fog. interviews with the flight crew of this and other affected aircraft, review of the relevant radio and radar data. This advice is also available by dialling 1300 659 210. 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. However, this reduced their options after the unexpected need to divert from Adelaide to a suitable alternate destination. All rights reserved. Jennifer has hit onto an important point worldwide, especially the changes in sea surface temperature instrumentation and protocols (70% of the globe). 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. 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). 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. For those interested in checking out popular landmarks while visiting Mildura, Kar-Rama Motor Inn is . 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 controller on duty on 18June2013had 9 years of experience in the operations department at Virgin. The flight crew continued collecting weather updates for various ports as the flight progressed, including Mildura, Melbourne, Canberra, Sydney and Adelaide. The ILS transmitter was a Category 1 unit with a minimum visibility of 1,200 m required for landing. imagine a nearby lightning strike producing a believable pulse. ATC radar limitations and frequency congestion may also be factors in limiting the controllers capability to provide additional service. number of redundancies available in the event of a system component failure. 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. The FOs roster showed that 16 and 17 June 2013 were rostered days off. They cover how the data are obtained, how they are processed, and what each column means. 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. The Velocity 1384 FO replied that they were in the same boat but, after discussion between the captain and FO of Velocity 1384, they elected to hold and allow Qantas735to continue with the approach. Latest Weather Observations for Mildura IDV60801 Issued at 9:22 am EDT Monday 16 January 2023 (issued every 10 minutes, with the page automatically refreshed every 10 minutes) About weather observations | Map of weather stations | Latest weather observations for VIC | Other Formats Station Details ID: 076031 Name: MILDURA AIRPORT Lat: -34.24 IDCJDW3051.202211Prepared at 16:01 UTC on Monday 16 January 2023. The forecasters then decided to amend the Adelaide TAF at 0700 to include a 30 per cent probability of fog. As a result, the crews were compelled to land at Mildura in conditions below the minima permitted for landing, with Velocity 1384 also landing below their required fuel reserves. This was because the Aeronautical Information Publication (AIP) Australia stated that a TAF that is valid for 30minutes prior to the arrival must be used for flight planning purposes. Aviation Verification System (AVS) 2 (due to be completed in 2017). ISO 17025) for any of its AWS. 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. In addition, it was noted that: Flight information will be made available, whenever practicable, to any aircraft in communication with an ATC unit, prior to takeoff or when in flight, except where such service is provided by the aircraft operator. This included clarification of the minimum requirements of the service provided (i.e. This encapsulated the pre2009 FIS change through to the occurrence at Mildura. 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. Given the TAF only had a 30 per cent probability of fog, and as the aircraft was in the sterile cockpit phase of flight, flight watch did not pass the TAF to the crew at this point. inadvertent flight below the minimum permitted altitude. This change came about, in part, due to the introduction of more automatic weather stations, which increased the amount of data available for various airports. Cloud cover is normally reported using expressions that denote the extent of the cover. It is broadcast automatically and continuously and contains information required for takeoff and landing. On this basis, the decision was made that, given Velocity 1384 was planned to arrive at Adelaide at 0920, they would not be affected by the fog. The forecast TEMPO was still considered by BoM to be appropriate for the conditions; however, at around 0930, the visibility at Mildura abruptly decreased. Conversely, if crew are not aware, or primed, of a situation they may not recognise relevant information that could assist their decision making. A further article in the Flight Safety Australia, MarchApril 2012 edition, outlined the provision of ATCinitiated flight information services. Change location Start typing (town, city, postcode or lat/lon), . Trial Automation of Observations at Cairns and Canberra (TAOCC) Project. This magazine was produced by the Civil Aviation Safety Authority and distributed to pilots and other aviation personnel. The bureau needs a big shake-up from the top down. 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. At that stage, the No. For the remaining short haul domestic operations, primarily under 90 minutes flight time, the flight following service was considered as available, and was dependent on flight watch personnel workload at the time.

For the deterioration at Adelaide, ATC did not need to use the Hazard Alert prefix as the deterioration was in a current meteorological product. The systems supervisor was completing the final day of a 2day endorsement check for the position, and operating under supervision at the time of the occurrence. There is also a note stating METAR QNH does not meet this requirement. Chance of any rain: 20% Partly cloudy. 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. These conditions were reported back to Qantas 735 as including a visibility of 700 m in fog. In order to access information from an AWIS, an aircraft needs to be within VHF range. 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). There is no regulatory requirement to carry alternate aerodrome fuel in the case of a code grey forecast and they are not routinely referred to by short haul flight crew or in the construction of flight plans for short haul domestic operations. Aerodrome Forecasts are a statement of meteorological conditions expected for a specific period of time, in the airspace within a radius of 5 NM (9 km) of the aerodrome. 159166.
