Parallel data from Mildura preliminary findings. 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 flight crews of Velocity 1384 and Qantas 735 gave precedence to the aerodrome weather reports at Mildura over the aerodrome forecast when deciding to divert. These are useful, for example, for identifying fog and low cloud, which may not be visible in thermal infrared images because it has a similar temperature to the ground below. I am shocked that as late as the 90s and 2000s they were not taking every precaution in preservation of a national and world treasure. A standard ground aid to landing, comprising two directional radio transmitters: the localizer, which provides direction in the horizontal plane; and the glideslope, for vertical plane direction, usually at an inclination of 3. 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. As such, they did not always represent a significant or unforecast deterioration. 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. 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. 76 Deakin Avenue, Mildura VIC Australia As they taxied in, the captain told the cabin crew to stand down and normal arrival procedures resumed. This TEMPO meant that anyone flying to Mildura Airport required either 60 minutes of holding fuel to outlast the predicted deterioration, or needed to nominate an alternate destination airport. The MATS section on hazard alerting required ATC to prefix an FIS call with Hazard Alert in the case of a change to a component of FIS not described in a current meteorological product or NOTAM. accuracy of aviation meteorological products in Australia. At 1004, as they were not visual with the runway, the crew initiated a missed approach from 132ftAGL. ISO 17025) for any of its AWS. Given the meteorological conditions were less than the landing minima for a Boeing 737, this constituted an emergency. Changes in operational status of the aerodrome of intended landing, alternate aerodromes and deviations from the original flight plan, shall be taken into account. Prior to the changes to the AIP and MATS in March 2009, ATC notified pilots receiving an ATC service about all SPECI reports and amendments to forecasts. 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.. 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. You do not have a default location set visibility is the average distance that distinguishing obstacles can be seen around the aerodrome. 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). If the ETA is outside the validity of the TTF, then the weather requirements shall be determined from the current TAF. The controllers were supported by aisle supervisors and a systems supervisor. This was based on the knowledge that the cloud base would preclude becoming visual via a normal approach. 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). 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. Fog had not been forecast for Adelaide when the crew submitted their flight plan. 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. 2. 2 tank being selected OFF, leaving the No. Check and double check, review and test it. Web. The crew diverted to Mildura and the aircraft landed safely at Mildura Airport at about 1010following two instrument approaches. 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. The 0358 amended TAF for Mildura that morning forecast light winds and scattered cloud at 3,000ft and broken cloud at 6,000 ft. While conditions deteriorated after Qantas 735 landed, in different circumstances, the weather may equally have improved sufficiently to allow Velocity1384to hold, before landing in conditions above the minima. As their arrival time was 0917, the crew elected to continue to Adelaide at this point. Web. At 0922, Qantas 735 transferred to the same frequency and was also advised of the arriving traffic. There is no documentation, however, supporting this contention for Mildura or any of the other nearly 500 AWS spread across the Australian continent. At 0820, the aircraft reached its latest point of safe diversion back to Sydney. However, the airport and equipment had demonstrated the ability to support emergency landings below CAT I meteorological conditions during practice approaches. The crew of Qantas 735 asked ATC if the forecast improvement was likely to occur as expected. Forecasting fog for aviation purposes is known to present a number of challenges. An advanced hardware and software system that is used by Airservices Australia to help manage domestic and international flights in Australian airspace. The AIP did not contain a list of information that would constitute a Hazard Alert, or what constituted non-routine meteorological products. The size of the change was assessed as small and the magnitude of the change as reasonable. AIP GEN 3.3 sections 2.5.4 and 2.5.5 detailed the hazard alert service provided by ATC as part of ATC-initiated FIS. The ATSB also found that the forecasting process at Mildura Airport appeared to be conservative, with a high false alarm rate. This query was made on the same frequency as was being monitored by Velocity 1384 at the time. 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. Post:PO Box 105 Mildura VIC 3502Australia, Deakin Avenue Service Centre Qantass Flight Dispatch manual stated that information to prepare a flight plan included various sources of weather and operational information, including TAFs. The aircraft had departed Brisbane at about 0630 that morning and carried sufficient fuel for the flight to Adelaide. This display, together with an explanation of the LOW FUEL, FUEL CONFIGURATION and FUEL IMBALANCE indications, is expanded at Figure 5. Information on the provision of hazard alerts was amended to require controllers to: Communicate a sudden (not forecast or NOTAMed) change to a component of FIS having an immediate and detrimental effect on the safety of aircraft by using the prefix Hazard Alert. The captain was the pilot flying and the first officer (FO) was the pilot monitoring. - Occurs when fuel quantity is less than 907 kg (2,000 lbs) in the related main wing tank. When the TTF for Adelaide was issued at 0800 and showed fog, flight watch again reviewed the situation for applicability to Velocity 1384. 3.3.6 Where ATC units provide both FIS and ATC service, the provision of ATC service will take precedence over the provision of FIS whenever the provision of ATC service so requires. The FDR recorded a LOW FUEL QTY message for both main wing tanks at about 0955. 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. Given electronic probes generally respond more quickly to fluctuations in air temperature than mercury thermometers, it follows that this method instantaneous recordings from an electronic probe would result in new temperature maxima under the same weather conditions. observations list type; observations; sky observations; Sunday January 8, 2023. choose date: local weather; observations; sky conditions; daily summaries; climate; 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 Figure 1: Approximate aircraft positions at 0700, when the amended forecast for Adelaide was issued with a 30 per cent probability of fog, Figure 2: Approximate aircraft positions at 0800, when the trend forecast for Adelaide was issued with fog conditions forecast to lift at 0900, Figure 3: Approximate aircraft positions at 0900, just prior to initiating the diversion to Mildura. The section went on to state the prevention of collisions and expediting of traffic will take precedence over this service. The initial public version of these safety issues and actions are repeated separately on the ATSB website to facilitate monitoring by interested parties. Mildura - Archived Radar - Rain Close menu Home Radar Observations Satellite Forecasts Video Map Login Register Account Logout 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. The TAF also included TEMPO periods between 0500 and 1000 in which the cloud base was forecast to reduce to 600 ft AGL. View the current warnings for Victoria. Nothing in these instructions shall preclude officers from exercising their best judgement and initiative to assist pilots. The forecasters then decided to amend the Adelaide TAF at 0700 to include a 30 per cent probability of fog. The aircraft, operated by Virgin Australia, was en route from Brisbane, Queensland, to Adelaide, South Australia, with five crew and 86 passengers on board when the crew diverted the aircraft to Mildura. Instead, pilot awareness of the implications for the flight of the reported weather conditions is crucial to effective in-flight decision making. About 5 minutes after take-off, the crew sent a request through ACARS for the current Automatic Terminal Information Service (ATIS)[21] at Adelaide. In September 2015 the BOM implementation of Himawari 8 satellite data. Mildura, Victoria January 2023 Daily Weather Observations IDCJDW3051.202301 Prepared at 00:36 UTC on Monday 16 January 2023 Source of data Observations were drawn from Mildura Airport {station 076031}. During the investigation, the ATSB became aware that the En Route Supplement Australia (ERSA), which is a supplement to the AIP, and the Jeppesen Australian Airways Manual contained incomplete information on hazard alerting. Identify what items make you the most money and which items don't. Quickly view your stock levels and even see what's on order and when you can expect it.

Overall, given the intent of the supporting systems, the individual actions were predominately reasonable for the information the individuals had at the time. As a result, the systems supervisor contacted the BoM to advise them of the unexpected deterioration and that the current Mildura TAF did not reflect the severity of the conditions. Before departure from Singapore, the TAF for Perth Airport predicted a 30 per cent probability of fog after 0200 Western Standard Time[23]. This includes available information regarding nominated alternate aerodromes and unattended aerodromes enroute at which a landing is planned. Mildura Weather. It seems like a nasty trick may have been played on you because it is likely that all the data was available in electronic form. The BoM reported at the time that this was not unusual, as records showed that in the previous 20 years, fogs formed at both Adelaide and Edinburgh on about 50 per cent of occasions that it was forecast, with Edinburgh proving to be the greater risk. As the flight crew of Qantas 735 was preparing to depart Sydney, just prior to leaving the gate, the 0700 amended TAF for Adelaide was issued.
