Overall, given the intent of the supporting systems, the individual actions were predominately reasonable for the information the individuals had at the time. - Inhibited when centre tank quantity is less than 363 kg (800 lbs). Fuel tank capacity is indicated in Table 5. The FO of Velocity1384confirmed that this was consistent with their understanding of the Virgin flight following service for domestic operations. You should read the important information in these notes. Light winds becoming southwesterly 20 to 30 km/h during the morning then becoming light during the evening. Flight dispatch and flight following consisted of two modes. The flight crew of Qantas 735 queried the fog at Adelaide Airport with the en route controller in the sector prior to Tailem Bend, at around 0816. Landing below minima due to fog involving Boeing 737s, VH-YIR and VH-VYK, Mildura Airport, Victoria on 18 June 2013, forecasting and distribution of weather information by the Bureau of Meteorology, provision of weather and operational information by Airservices Australia to all aircraft that were affected by the reduced visibility at Adelaide, provision of weather and operational information to those aircraft by the operators. At this time, the Velocity1384 FO was out of the flight deck. They simply shout louder the same flawed (or worse) story. However, Jeppesen Air traffic rules and services,section 8.5 ATC initiated FIS did contain this advice. On board were six crew and 146 passengers. In addition, the BoM uses a non-standard method of recording temperatures from such devices. However, fuel uplift records from Sydney and Mildura, as well as flight plan fuel figures adjusted for taxi and auxiliary power unit fuel burn, enabled the ATSB to calculate if this requirement could be met. Often the reports were consistent with the forecast, or were triggered by an improvement in conditions. The estimated arrival time at Adelaide was 0917. As they taxied in, the captain told the cabin crew to stand down and normal arrival procedures resumed. This could be reduced to 1,133 ft if the actual aerodrome QNH was used (see below), although the visibility requirement remained at 6km. The B737-800 is equipped with three fuel tanks. Many factors (such as volume of traffic, controller workload, communications frequency congestion and limitations of radar equipment) may prevent a controller from providing this service. This imbalance was likely the result of the crossfeed valve being opened by the crew. 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. The FO reported a duty day on 16 June 2013 that included flying BrisbaneMelbourne and return with approximately 7 hours duty time. The flight crew of Qantas 735 conducted an instrument approach and landed below minima. This encapsulated the pre2009 FIS change through to the occurrence at Mildura. 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. 2 tank is integral with the right main wing and the centre fuel tank is located within the fuselage and extends into each wing. This advice is also available by dialling 1300 659 210. There was no corresponding guidance for application to crews in-flight planning. The information in amendment 58 was current at the time of the occurrence involving VHYIR and VHVYK. Data from the aircrafts flight data recorder (FDR) showed that at 0933, as Velocity 1384 was on descent to Mildura, a fuel imbalance developed between the main wing tanks (No.1 and No. Peters funding website is no longer accepting donations. The version of the AIP that was current on 15 March 2007 stated that, in relation to FIS, pilots were responsible for requesting information necessary to make operational decisions. The crew of Velocity 1384 reported using the observation reports to confirm their understanding of Milduras suitability as an alternate destination. In addition, pilots should note the potential benefits of informing the controller of a non-normal situation. The crew of Qantas 735 applied a revised minimum to the approach that was 200 ft lower than that published. 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. State and regional weather forecasts, current conditions, Bureau of Meteorology warnings, radar and satellite animations They do not adjust the data for differences in devices as they do not adjust the data for UHI. The B737 is equipped to conduct area navigation Global Navigation Satellite System (RNAV GNSS) approaches, which are classified as non-precision approaches. 2. As both aircraft were committed to landing at Mildura by this time this would not have influenced the occurrence. The broadcast is usually continuous with updates available on a minute by minute basis. The MATS also contained a section dealing with the provision of a hazard alert service. The forecasters then decided to amend the Adelaide TAF at 0700 to include a 30 per cent probability of fog. By filtering the above occurrences for those making some reference to ATC in the reporters text (870 occurrences), the ATSB found 171 occurrences with evidence that ATC provided assistance to the pilot, some of which was at pilot request. The observer advised the forecasting office that the mist and subsequent fog arrived rapidly from the south. Meanwhile, in the United States, (NASA boss and Mikey Mann champion) Gavin Schmidt and NOAA are busy adjusting the US surface temperature record to ensure its support for climate hysteria (while reflecting real world temperatures about as well as a fun house mirror). Chapter 6 Air Traffic Services, stated: Amended aerodrome forecasts shall be passed to aircraft within 60 minutes from the aerodrome of destination, unless the information has been made available through other means. 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. At 0946 the crew of Qantas735broadcast that they had landed at Mildura. However, the timely dissemination of such information optimises the likelihood of effective flight crew planning and decision making. The flight crews of Velocity 1384 and Qantas 735 had insufficient fuel to divert to another airport once they arrived at Mildura. Quality checks on data are not normally performed. The captain of Velocity 1384 reported that the required decision making and associated actions to return to Adelaide could be achieved in this timeframe. set your location User Guides Weather Link to Mildura Observations on BoM, or for more detailed weather and climatic conditions log in to Order Water. That is, there was an expectation that the crew would have been told about the fog in Adelaide when the condition commenced. a forum for the discussion of issues concerning the natural environment. This role included liaison with flight dispatch to update flight plans and manage diversions as applicable. The actual weather conditions encountered by the flight crews of Velocity 1384 and Qantas735 on arrival at Mildura were below landing minima and significantly worse than the aerodrome forecast and weather reports used by both flight crews to assess its suitability as an alternate destination to Adelaide. The captain had also held Training Captain/Approved Testing Officer approvals since April 2003. As such, the action to not pass this information to Velocity 1384 was provided for by the Virgin dispatch manual. At 0700, when the amended TAF for Adelaide was issued, Velocity 1384 was established at flight level (FL) 400 in the cruise. The increased number of automatically-generated weather observations increased the amount of weather being delivered to controllers consoles for various airports. It is the responsibility of the Tower to identify and coordinate Hazard Alert information relating to destination aerodrome(s) within activated civil or military control zones. The review determined that, because the TAF had only a 30 per cent chance of fog and the TTF issued at the same time forecast no deterioration, the amended TAF would not be passed to the flight crew. During the telephone call with the company meteorologist, the BoM supported the content of the 0800 TTF that the fog would clear at 0900. Light winds. The crew of Velocity 1384 (who were not authorised to conduct an autoland at Adelaide as Virgin did not have the appropriate approval from CASA to conduct an autoland) also used the observations at Mildura as the basis of their decision to divert to that airport. Light winds becoming west to southwesterly 15 to 20 km/h during the day. In response the forecaster contacted the BoM observer located at Mildura Airport. Various supervisors in Melbourne Centre advised that they were aware that the weather in Adelaide was deteriorating. Unless otherwise indicated, all times in this report are quoted in EST. AIP GEN 3.5 paragraph 4.1 defined aerodrome weather reports as: reports of observations of meteorological conditions at an aerodrome. These include increased monitoring and support as required and the potential to reduce pilot workload in stressful situations. The MATS that was valid at the time of the occurrence stated that if ATC is providing both controlling and FIS, precedence was to be given to the provision of air traffic control over FIS. You should read the important information in these notes. This project aims to develop a new national climatological interface for the display and interpretation of climate information at aerodromes and key aviation locations (due to be completed in 2017). 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}. The bureau needs a big shake-up from the top down. From this time, the imbalance began to increase again. Close menu. http://www.bom.gov.au/fwo/IDV60801/IDV60801.94693.json. Council continues to monitor flooding throughout the rivers that pass through the municipality.For the latest information, including flood warnings, road closures and support available, or to access our Community Relief and Support Service please click on the link below. [19] At that time, they were about 150 NM (278 km) south-west of Brisbane. Evidence from the relevant ATC enroute sector recorded radio communication showed that controllers were providing inbound aircraft within 60minutes of Adelaide Airport with advice of an amended TAF and of ongoing SPECIs. At certain airports, an Aerodrome Weather Information Service (AWIS) provides actual weather conditions via telephone or broadcast on VHF radio. The only section in the AIP that defined hazard alerting procedures stated: A sudden (not forecast NOTAMed) change to a component of FIS having an immediate and detrimental effect on the safety of an aircraft will be communicated by ATC using the prefix Hazard Alert. However, on the day the fog did not clear as anticipated, which resulted in the forecast end period for the fog being inaccurate. The AIP Australia detailed the various elements of flight information service (FIS), including that pilots are responsible for obtaining information necessary to make operational decisions. 1 tank to supply both engines. The article did not contain a definition of non-routine MET products but did contain the following practical example of what ATCinitiated FIS would not include: you will not automatically receive routine TAF information showing deteriorating weather conditions if you are en route to a location [bolding in original]. Review of Flight Watch/Following activities across several carriers to obtain best practice for this activity Virgin America and Westjet were visited. Madden Avenue Service Centre108 Madden Avenue, Mildura VICAustralia IN September 2017, the Australian Bureau of Meteorology (BoM) claimed a series of new record hot days across south eastern Australia, including on 23 September at Mildura. Mildura - Archived Radar - Rain Close menu Home Radar Observations Satellite Forecasts Video Map Login Register Account Logout However, it can be difficult to differentiate between fog and low cloud when using satellite imagery. The Mallee controller acknowledged the report but, at that stage neither Velocity 1384 nor Qantas 735 were on the Mallee frequency. The BoM reported that their assessment of Mildura at around 0830 showed that low cloud was more likely to occur than fog. This resulted in the need for both Qantas 735 and Velocity 1384 to land in conditions that were below minima. The captain was the pilot flying and the first officer (FO) was the pilot monitoring. They should be taking, and reporting, parallel measurements to confirm that the probes are measuring the same temperatures as a mercury thermometer would. Email:mrcc@mildura.vic.gov.au At 0800, the TTF for Adelaide showed visibility had reduced to 1 km to the north-west and that patches of fog and shallow fog were present. ATC radar limitations and frequency congestion may also be factors in limiting the controllers capability to provide additional service. The changes were specifically introduced to reduce controller workload. Bureau Home > Australia > Victoria > Forecasts > Mildura Forecast. The controllers were supported by aisle supervisors and a systems supervisor. The AIP outlines the elements of ATC-initiated FIS. Area Average Intensity . (i) other activities likely to affect safety. They also obtained the TAF showing a TEMPO and reported calculating that they could meet this additional fuel requirement for Mildura. As such, the TAF that was valid at the time reflected a temporary period of low cloud that was expected to last between 30 and 60 minutes (TEMPO), rather than fog. This emphasises the importance of the BoMs ongoing efforts to improve the accuracy of meteorological forecasting. Cloud cover is normally reported using expressions that denote the extent of the cover. Additionally, in this occurrence, the observations showed the weather at Mildura was better than forecast at the time the diversion was initiated. 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. The SCARD determined that a safety case was not required as there was no change to the Air Traffic Services Provider Certificate. Both allowed aircraft to be dispatched without carrying alternate fuel if the weather forecast for the destination did not require an alternate. FL400 equates to 40,000 ft. The flight watch dispatcher was responsible for maintaining flight watch services, either by actively monitoring, or passively following various assigned flights (see the section titled Flight dispatch and following). About Latest Weather Observations and Fail operational capability is the minimum capability to conduct Cat IIIB, and some Cat IIIA ILS approaches. 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. Taking into account the forecast fog and these holding requirements at Melbourne, neither Velocity1384nor Qantas 735 had sufficient fuel to proceed to Melbourne from Adelaide. As a result, significant weather deteriorations may remain unnoticed unless the pilot: The inherent passivity of the ABS increases the risk that potential landing options will unknowingly reduce in critical situations. 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. 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. The ATSB also found that in certain weather patterns and at certain locations, fog is both rare and difficult to forecast reliably. Im of the view, having casually observed the BoM 7-day forecasts vs actuals during this summer that theres a constant 2C to 3C over-forecast by the BoM to the point that it has become a bit of a joke in our household. While runway 16 at Melbourne Airport met the requirements of flight instrument procedures requiring autoland capability, on the morning of the occurrence, the forecast for Melbourne was for low cloud and a 30 per cent chance of fog until 1000. The river height will reach 38.3 metres at the Mildura Weir 113 millimetres higher than the . 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. And they fail! The TTF predicted that the fog would clear at 0900and the company meteorologist called the BoM to determine the forecasters confidence that the fog would clear at 0900. A ground-based transponder station. To 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. Furthermore, controllers were to notify the pilots of aircraft affected by non-routine meteorological products at the time that the products were identified in the form of a directed transmission to the pilots and within 60 minutes flight time of the conditions notified. 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. In addition, a notice to airmen (NOTAM)[14] listed holding requirements for Melbourne. The investigation is continuing and will: The information contained in this Interim report is released in accordance with section 25 of the Transport Safety Investigation Act 2003 and is derived from the ongoing investigation of the occurrence. Forecast for the rest of Saturday Summary Partly cloudy. [2] The fuel on board at take-off from Brisbane was 8,800 kg as recorded on the flight data recorder. During the flight, the conditions deteriorated below those forecast for the area, requiring a diversion first to Leinster, where the conditions were worse than forecast. The reasons for reviewing Trend Forecast services include: Aviation Cameras for Forecasters (AvCam). That discussion did not result in a change to the valve position and it remained open. This TAF forecasted a visibility of 3,000 m in mist, with scattered cloud at 300ft AGL and broken at 4,000 ft AGL. Many non-major airports in Australia have an AWIS and, as this is classified as an ABS, ATC will generally not alert pilots to significant deteriorations or improvements in specified weather condition (SPECIs) at those locations. Ltd. as Velocity 1384 and VH-VYK operated by Qantas Airways Ltd. as Qantas 735, were on scheduled flights to Adelaide, South Australia. The onset of fog at Perth Airport at the estimated time of arrival was not forecast until after the aircraft had passed the point in the flight when it had insufficient fuel remaining to divert to a suitable alternate airport. The DME or GNSS arrival had a circling minima of 980 ft for large jet aircraft. The chance of a thunderstorm, possibly severe. In part, these included: (b) FISE: the exchange on the FISE [flight information service en route] frequency of information pertinent to the en-route phase of flight. Wouldnt it be possible to simply put an electronic probe and a classic thermometer into a Stevenson enclosure or a temperature controlled environment for comparison? At 1012, ATC initiated a distress phase. Virgin advised that a review of their operations identified no systemic issue in relation to flight crew seeking weather information. They then continued to collect weather updates for various ports, including Mildura, Melbourne, Canberra, Sydney and Adelaide. In particular, in relation to this occurrence, it was noted that pilots would have expected the crews of Velocity 1384 and Qantas 735 to have been told of the fog at Adelaide prior to changing to the Tailem Bend sector frequency. At the time of the A320 occurrence on 20August1999, there had been 11 fog events recorded at Adelaide Airport during 1999. The dispatch duty manager had oversight of the dispatch and flight watch functions at Qantas Airways Ltd. (Qantas). 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). Check and double check, review and test it. Light winds. The visibility then fluctuated before dropping below 1,000 m at 0947. The electronic probe that measured the record hot day on 23 September 2017 was installed on 27 June 2012 and I was initially told that there was parallel data only available through until January 2015. The aircraft was positioned for a second approach, during which the cabin crew were briefed and prepared for an emergency landing, briefing the passengers to brace accordingly. The aircraft was refuelled and the flight returned to Darlot once conditions improved. The next warning will be issued by 03:00 pm EDT on Thursday 19 January 2023. The Pilot in Command may adjust the DPA to be a geographical point, other than a position on the Fuel Flight plan (i.e. During the latter stage of the flight, unforecast fog developed at Sydney, which resulted in the deterioration of visibility to below the landing minima. On board were 6 crew and 146 passengers. In addition, the onset time of fog at Adelaide Airport that day was 40minutes later than any recorded onset time at that location in the preceding 30 years. This is particularly the case if the sole report is consistent with the current forecast, as in this instance, when the low cloud at Mildura as reported by the air ambulance pilot was already forecast. The inaccuracy of the forecast clearance of the fog at Adelaide Airport compelled the flight crews of Velocity 1384 and Qantas 735 to either conduct an emergency landing at Adelaide or divert to Mildura Airport. The BOM are employing clowns? Partly cloudy. 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. As the crew of Velocity 1384 did not obtain the updated weather for Adelaide Airport while en route, they remained unaware of the deterioration until quite close to Adelaide. The crew diverted to Mildura and the aircraft landed safely at Mildura Airport at about 1010following two instrument approaches.
