Quote:Ground-breaking aviation research to reduce unforecast weather risks
ATSB senior research analyst Dave Wilson is working on a research investigation that will raise awareness of potential weather-related risks among pilots and also examine the effectiveness of rules that have been in place for more than 30 years.
Weather planning rules in Australia are unique compared to countries in Europe and North America. Because weather in Australia is generally good, risks are very low. But when weather is unsuitable for landing, these differences can have a real world effect on aircraft operations. It is these effects that Dave’s research aims to quantify.
A number of unforecast weather episodes relating to flights into major Australian airports have led to unforeseen diversions, holding and, in some cases, landing below published safe limits. Dave’s research is seeking to understand how the reliability of weather forecasts affects the ability of flight crew to conduct safe landings.
“I want to help decrease the likelihood of pilots being exposed to unexpected and unsuitable conditions for landing,” Dave said. “The likelihood of an accident happening because of conditions unsuitable for landing is low. But in making it even lower, the probability of a major accident happening reduces considerably.
“Initially I’m looking at Mildura and Adelaide airports. At Mildura, 99 per cent of the time, the weather is suitable to land a large aircraft. But based on the data I’ve looked at, there is still a remote possibility you may have an unreliable forecast. With the volume of air traffic, this could affect up to four aircraft per year.
“If you look at Adelaide, the chances of a single flight crew being exposed to an unreliable forecast are lower. However, when you take into account fluctuations in weather reliability, and the aircraft traffic arrival patterns (around 50,000 per year), the potential to result in a catastrophic accident increases. That’s what we want to avoid.
“If you’re in the air and you get to the point of last safe diversion—where you’ll be committed to landing at the planned destination—if the current forecast predicts marginal conditions, questions are raised as to whether continuing to the planned destination or diverting to an alternate destination should be required. This scenario has been a particular focus of this research.”
Dave has a vested interest in his research. Several actually. He’s a pilot who first flew solo when he was a 15-year-old student at Caringbah High in Sydney—well before he could legally drive. The opportunity of subsidised flying with the Australian Air Force Cadets was too good to knock back. He has since flown aerobatics out of Bankstown Airport but has undertaken little flying over past two years while pursuing this research.
Dave also has degrees in Aeronautical Engineering and Physics from Sydney University. It was there he attended a guest lecture by Pierre Blais from the Directorate of Defence Aviation and Air Force Safety (DDAAFS), which set him on a path to the ATSB.
“It was then that I thought investigating aviation safety would provide the ultimate career path for me. I find it both meaningful and challenging,” Dave said.
The research was initially going to secure Dave a Master’s degree. But he is now upping the ante and aiming to pursue a Doctorate. A stumbling block is finding reviewers with sufficient expertise in a related field. When you’re breaking new ground, this is often the case.
After first working at the Department of Infrastructure as a vehicle compliance engineer, Dave came to the ATSB to embrace his love of aircraft, engineering and how things work. Now with six years under his belt, Dave is also considering his future. “I’m happy as long as I’m being challenged,” he said. “But after this research is completed, I wouldn’t mind also undertaking a broader range of transport safety investigations.”
Research on Adelaide and Mildura aerodromes is expected to be published by the end of 2016. Progressive reports for each major aerodrome in Australia and four of our remote island aerodromes (Norfolk, Cocos, Christmas and Lord Howe) will be progressively released over the next year or two.

Quote:New research doubles chances of landing safely in unforecast weather
New ground-breaking research released by the ATSB is expected to double the chances of aircraft landing safely during times of unforecast weather. This is the first report in a series covering Australian airports supporting regular passenger transport operations.
The ATSB investigator leading the research project, Dave Wilson, has analysed an enormous amount of weather and aerodrome data to identify weather-related safety risks for Adelaide and Mildura airports.
Mr Wilson said there were around 50,000 arrivals at Adelaide each year. The likelihood of encountering unforecast weather and having to adopt a contingency plan, such as diverting, was a rare occurrence—about one in 3000.
By developing sophisticated algorithms from the data, the research makes arrival without sufficient warning even rarer—perhaps as low as one in 10,000.
In so doing, the predictive nature of the research means enhanced safety for the travelling public in Australia.
“By reducing the number of aircraft being caught out, we significantly reduce the chance that something will go wrong,” Mr Wilson said.
“As an example, if you take mornings in Adelaide, retrieving a forecast an hour out from landing could double the chance of a safe arrival compared to three hours out,” Mr Wilson said.
“Every year there are circumstances where forecasts don’t provide sufficient warning for pilots. This means they have to divert or, in some rare cases, land below specified limits with critically low fuel levels.”
This occurred in 2013 when two Boeing 737-800 aircraft were forced to divert to Mildura from landing at Adelaide, where poor weather was also encountered. One of these aircraft landed below the specified safe limits with limited fuel remaining.
The research will benefit all aviation operators but, purely due to the number of flights, will be more useful for high capacity commercial transport. Operators will be able to use the research to help guide operational staff such as dispatchers, who support their pilots by helping to focus attention on high risk times of day and seasons of the year.
It will also be of strategic use to the Civil Aviation Safety Authority, Airservices Australia and the Bureau of Meteorology.
“We can identify high-risk locations and high-risk times of day and year, and when this is used with flight planning and operational rules for landing, safety can be enhanced. It will also allow for better decision-making with respect to the prioritisation of investment decisions about aircraft and aerodrome navigational equipment,” Mr Wilson said.
This research is tangible evidence of the direction in which ATSB Chief Commissioner Greg Hood wants to take the organisation.
“The ATSB is committed to becoming a data-driven, predictive transport safety investigator,” Mr Hood said. “We will continue to source data nationally on aviation transport safety occurrences and events and use that data to identify and communicate safety risks and emerging trends.”
Over the next two years Mr Wilson will expand his research and evaluate billions of rows of data to produce a series of reports documenting weather-related safety risks for regions around Australia. The research ultimately has the potential to be applied not only in Australia, but around the world.

The cynical beast roars WTF in protest as I read the latest ‘puff piece’ from ATSB. The urge to vomit at the soft sell of ‘Dave the Saviour’ reads as though it was written to be inserted between recipes and advice on how best to remove stains from underwear in one of those journals for the mentally challenged, they leave lying about in waiting rooms (does anyone actually pay hard earned for that crap?).
Anywhere else on the planet the simple rule of 1, 2, 3 applies to your pre flight fuel planning (in broad terms)
IFR Alternate Airports (1-2-3 Rule).
When filing an IFR flight plan, you must include an alternate destination airport when the weather forecast at your original destination predicts conditions below those specified in CFR 91.169. To help remember those conditions, you can use the 1-2-3 rule.
1 - During the time 1 hour before to 1 hour after the estimated arrival time
2 - Ceiling less than 2,000 feet
3 - Visibility less than 3 miles
If the above conditions exist, an alternate airport must be filed.
The alternate airport also has requirements that it must meet.
• If the airport has an instrument approach published, the weather must be forecast to be (at the ETA) better than the alternate airport minima specified in that approach or the following standard conditions:
o Precision Approach: 600ft ceiling and 2SM visibility
o Non-Precision Approach: 800ft ceiling and 2SM visibility
Not in Australia – crew are hung out to dry, forced to make all decisions and be legally responsible for ‘getting it wrong’. The BoM factor something like 70% +/- error on their forecast conditions, let the computers do the modelling and waltz off, Scot free, whenever they get it wrong; or, the system fails to get the 'new' information delivered in time for that information to be of any value.
But no matter, our latest new best mate ‘Dave’ is going to do an ‘academic’ study for his degree and we must have the good manners and patience to wait for the results, until he has finished buggering about editing and refining his ‘thesis’, to impress other academics and further his own CV, while we pay him to do so. Bollocks - we don't have the time to fanny about, waiting on his pronouncements.
Pel-Air and the Mildura cock-up tell the tale of organizational and systematic errors very clearly. Only a degree in common or garden sense is required to see the gaping holes in not only the safety net, but in the lines of responsibility. No one has offered a solution, but all, except the flight crew, have gilt edged ‘get out of jail cards’. A company like Qantas have been operating a system of ‘cut out’ points for making diversion decisions for donkeys years now; all the expertise we will ever need is contained within the collective wisdom of their system. Why not ask them, politely, to share that ‘wisdom’ and adopt that advice into law?
I could, if I tried, care a little less about ‘Dave’s’ ambition and his aerobatic experience. This fluffy little bit of scripted bullshit typifies the standard approach to any and all ‘operational’ problems. Anything will do but address the problem head on and sort it out, quickly, effectively and properly.
I tire of the Hood ‘touchy- feely’, soft –softly, apologetic approach: that ducking ‘correcting the record’ thing they do is too pathetic to even be risible. Does he not realize that the organization he runs is a sad, sorry, failed, bloodless imitation, a sick parody of what it is meant to be.
