This prevents further degradation of these types of abnormal situations. In relation to the use of observation reports for in-flight planning, CASA noted that weather observations are not a legal instrument to determine if an alternate should be held or for fuel planning, unless the observation has a trend appended to it (eg TTF). Area Average Intensity . When Peter Ridd shows the world whats been going on in the scientific community, I hope the politicians who are sitting on their hands will start taking all these issues more seriously. 128 km Mildura Radar Loop Provides access to meteorological images of the Australian weather watch radar of rainfall and wind. Given the speed in which it developed, the fog was forecast to dissipate in about 12 hours. [8] As the AWIS for Mildura was not broadcasting due to an unserviceability, the inbound aircraft could not obtain this information from the AWIS (see the section titled Aerodrome weather information service). - Occurs when fuel quantity is less than 907 kg (2,000 lbs) in the related main wing tank. 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. Good girl Jennifer. Concerned about your property? As a consequence, the data for this period from the mercury thermometer is not normally distributed, as shown in Figure 1. Meanwhile, if we consider the residual available parallel data the very hottest days according to readings from the electronic probe (30 November 2012, 18 January 2013, 5 January 2013, 8 January 2013, 6 January 2013, 1 December 2013, highest to lowest) have no equivalent reading from a mercury thermometer. a PNR [Point of No Return]), if necessary. Despite not being passed the updated weather information from their flight operations centre, the crew of Velocity 1384 had two opportunities to become aware of the deterioration in Adelaide prior to being notified at 0844 by the Tailem Bend controller. 1 tank to supply both engines. A ground-based transponder station. This would indicate that the actions of the Mallee controller, which were reportedly influenced by workload, were not symptomatic of a systemic issue in the provision of flight information service (FIS). 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. At this time, the Velocity1384 FO was out of the flight deck. This workload was related to the five inbound aircraft, all of which required traffic information on each other, and other aircraft within the Mallee sector. The exchange between ATC and Qantas735was not captured on Velocity 1384s cockpit voice recording as it only recorded the 2hours preceding engine shutdown. 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 flight crews of Velocity 1384 and Qantas 735 planned for, and uploaded, sufficient fuel for the forecast conditions at Adelaide Airport in accordance with the respective operator's fuel policies. ATSB Recommendation No: AO-2013-100-SR-057. At interview, the first officer (FO) of Velocity1384 confirmed that this was their understanding of the flight following service for domestic operations. Knowing the value of the record as the basis for multi-trillion-dollar future policy decisions, how much is too expensive to leave a Stevenson box alone except to install a small remote camera to take the readings? These findings should not be read as apportioning blame or liability to any particular organisation or individual. Another Virgin aircraft then asked ATC to clarify if that report was for Melbourne, to which ATC responded negative, Adelaide. A number of information sources are available to assist this in-flight decision making in relation to assessing the weather affecting a flight and the need to divert to an alternate destination. Employed to minimise unnecessary distractions during critical phases of flight. Slight chance of a shower. I am dragging up my old university stats to understand what you are on about. . The forecasters then decided to amend the Adelaide TAF at 0700 to include a 30 per cent probability of fog. Typically, this means flying in cloud or limited visibility. The approach was being conducted in instrument meteorological conditions. In addition, some of these unforecast deteriorations were observed during approach, meaning the deterioration was only just prior to the arrival of the aircraft. 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. ATC, FSSs and, if applicable, AOCC [airline operations control center] VHF/HF voice remain as a redundant method of communicating aviation weather, NOTAMs, and other operational information to aircraft in flight. This resulted in the need for both Qantas 735 and Velocity 1384 to land in conditions that were below minima. This resulted in a significant increase in controller workload. Likewise, when the 0800 TTF was issued showing fog, both aircraft were still outside this 60minute arrival time. A further review of the ATSB occurrence database identified five occurrences that had happened since 1999 and were similar to this occurrence. Flight watch personnel at Virgin reported reviewing this TAF for applicability to Velocity 1384. The pilot reported weather conditions at the airport for the information of inbound aircraft. 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. Other formats To print this page, get the PDF version (one page, 45 kb ). That was, the FO was not expecting to necessarily be sent amended weather by flight following personnel. At the time that Velocity 1384 departed Brisbane, the TAF current for their arrival into Adelaide forecast fine conditions. The FDR recorded a LOW FUEL QTY message for both main wing tanks at about 0955. 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. Subsequent TTFs were issued for Adelaide, each extending the predicted time for the fog to clear. As the wind was forecast to tend southerly, and fog and low cloud were rare in a southerly flow at Mildura, the decision was made to continue with the current TEMPO. The Pilot in Command may adjust the DPA to be a geographical point, other than a position on the Fuel Flight plan (i.e. In order to access information from an AWIS, an aircraft needs to be within VHF range. The aircraft landed on runway 27 with the required fuel reserves intact and the crew reported that the runway was visible once they descended below the cloud. Aviation is a complex, highreliability industry. If an ABS is not available, pilots may request weather information from ATS as part of the on-request flight information service. Readmore. At interview, a dispatch duty manager reported that flight plans are calculated using the relevant TAF rather than a TTF. The ATSB has been advised of the following proactive safety action in response to this occurrence. The FOs relevant aeronautical experience is outlined in Table 2. 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. View the current warnings for Victoria. PSS I shall probably add to the above post (by way of an update) in the next day or two, with my most recent correspondence to the Head of the Bureau, Andrew Johnson. 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 this instance, the controller did not pass the AIREP to incoming aircraft nor to their supervisor, who could have informed BoM of the deterioration. The BoM subsequently advised the ATSB that there was no procedure in place to require a forecaster to request multiple reports of deteriorating weather before amending a forecast. 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. The estimated time of arrival at Adelaide was 0920. 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 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. number of redundancies available in the event of a system component failure. The estimated arrival time at Adelaide was 0917. These flights were always provided with relevant updates regarding weather and operational information. The latest weather forecast is available at www.bom.gov.au/nsw/forecasts. At a number of the AWIS locations, the broadcast is pilot-activated via radio. 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. In. - Displayed until any imbalance is reduced to 91 kg (200 lbs). 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. 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. As a result of this development, the forecaster issued an amended TAF for Mildura at 0952 that was valid from 1000. The captain of Velocity 1384 reported that the required decision making and associated actions to return to Adelaide could be achieved in this timeframe. More. It caters predominately for aircraft operating in control areas within VHF range of the facility. #5 of 11 B&Bs / Inns in Mildura. While the increase in data was a benefit to BoM, an unexpected outcome was the production of numerous AUTO SPECI reports. The captain of Velocity 1384 similarly reported that they considered the option of an autoland at Adelaide. 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. - Digits on tank(s) with low fuel quantity turn amber. The chance of a thunderstorm in the afternoon and evening. Another Virgin aircraft then asked ATC to clarify if that report was for Melbourne, to which ATC replied negative, Adelaide. However, the calculation techniques and reporting frequency are different. Peters funding website is no longer accepting donations. In the case of Mildura, the quality and length of the available parallel data makes it difficult to draw any real conclusions about the equivalence of measurements from the electronic probe installed in July 2012, with measurements from earlier probes and/or the mercury thermometer first installed back in 1889. Cloud unexpected significant variations to amount, base or tops (by reference to QNH); Visibility reduced due fog, mist, hail, rain, snow or dust, improvement observed; Wind significant variation to forecast; Other Phenomena incidence of severe or moderate turbulence, thunderstorms, moderate or severe icing, hail, line squalls, standing waves or winds of 40 KT or more within 2,000FT of ground level. At that time, the mainstream media reported this as a new record for the state of Victoria, specifically claiming it was the hottest September day ever recorded all the way-back to September 1889. Almost immediately, the crew obtained visual reference with the runway, discontinued the missed approach procedure and landed. 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. The ABS and the on-request service remained as described in the previous version of the AIP. Finding an ideal family-friendly small hotel in Mildura does not have to be difficult. Light winds becoming west to southwesterly 15 to 20 km/h during the day. [2] The fuel on board at take-off from Brisbane was 8,800 kg as recorded on the flight data recorder. VH-VYK was fitted with a very high frequency (VHF)/ aircraft communications addressing and reporting system (ACARS), which was routinely used by Qantas flight operations and flight crew.
