Re: [Aus-soaring] Training Value of 400 to 500 AGL flight: for a very rare reality...
I have been sitting on the sidelines hoping this thread would die, before someone. I can't help but think that low level aero tow cable breaks is a very rare problem that is about to be on the increase, just 'cause we are all talking about it. I have been gliding for 40 years and a tug pilot for 35. In that time I have never had a low level aerotow rope break for real! I have had 2 occasions when the rings pulled out of the eye splice in rough wave/rotor conditions well above 1,000 AGL. I have never broken the weak link. And as tuggie I was once told to expect a 300' release on tow. I went to idle cut off, got out of the tug and asked the instructor just where he thought the glider would go [from 300' over the far fence]. He agreed to defer the [asinine?] exercise to 600'. I learnt on winch and had plenty of low level cable breaks, but the only option there is to get the nose over fast, see 50 kts indicated and complete the landing ahead. So let's temper the discussion with the statistics of low level aerotow cable breaks. My guess it is way less than 1% of tows, whereas intentional training exercises may be 2%. I suggest that a low level aero tow cable break is a rare challenge, and the training exercise should be comparably rare. Alan Wilson Canberra. PS. I remember well a senior RAAF instructor telling me THE most dangerous time in an aircraft is with two instructors on a check ride.

Re: [Aus-soaring] Training Value of 400 to 500 AGL flight: for avery rare reality...
Alan, Basically some of this is what Mike B was saying earlier, and I certainly agree that an aerotow rope break is very rare, and it is most likely to occur (under normal circumstances), on taking up slack. Once upon a time, (as an early solo pilot), I had a launch behind a tuggie (in a 260hp Pawnee) whose side window opened inadvertently (I later learnt), just after I transitioned into flying mode. I think the window falling open may have scared the bejeezes out of him and he instantly cut the power. The situation then became interesting, especially as the particular strip we were using that day was rather short, with a recently subdivided and fenced estate ahead - read nowhere to land off aerodrome. Of course to add to the interest, I did not have the faintest idea what the tuggie would do next after cutting power! As a tuggie of vast experience, (as opposed to my tuggie at the time), what would YOU have instinctively have done here? Regardless of this, the lesson is very clear that any glider pilot, in command, has to be on the ball, and accept that he/she may have to cope with the unexpected. That is what instruction is (in part), about.

Cable breaks on aerotow are rare but low level emergencies extend beyond a breaking tow line. Tug problems requiring the glider to release are not uncommon. I've witnessed a tug starved of fuel at 200' (tug pilot forgot to change tanks), I know of tug engine failures occurring at low level, and I've had a student pull the bung at 100 feet when turbulence rocked the tugs wings (the kid thought it was a wave off and we OUTLANDED straight ahead). Then there are the engine failures on takeoff or failure to get airborne with self launching sailplanes. Misjudged circuits have also resulted in many accidents. It is a fact that almost all accidents occur to pilots who would normally be expected to know better, and all pilots need to be occasionally reminded of their vulnerability so they fly within the limitations of their knowledge, experience and ability. During check flights, instructors should make the effort to reproduce as carefully and realistically as possible the kind of stress that a pilot will encounter from time to time. Mike Valentine and others before (Howland), and after (Olerhead), were/are advocates of placing pilots placed under artificially induced-stress to facilitate the learning of how to manage both the flight itself and the stress level. This is sound practise in my view.

Why the 60 degrees bank for minimum height loss? Strictly you are correct, for minimum height loss you would have zero angle of bank, but the you would be able to get around. The 60 degree bank provides you with a smaller turn radius, it is a compromise between height loss and getting the aircraft back around.

Re: [Aus-soaring] Training Value of 400 to 500 AGL flight
Training Value of 400 to 500 AGL flight Energy management is what is being demonstrated. Any instructor / experienced pilot knows that. right? The instructor is there to ensure that the non-manoeuvring area is not entered etc and that the 'student' follows his/her pre determined plan (at least the basis of it), as well as determining if the pilot is maintaining co-ordinated flight throughout whilst 'under pressure'. 400' is not the place to think of numerous options and have a debate with yourself which one you should use. I have found it amazing the number of pilots who do not follow their 'plan' once presented with a launch failure. (Pre launch check is a good place to do 'the maths' Michael mentioned) 400' simulated launch failure, 100' over the finish line, first time 10km from the airfield at 1500'. All nice scenarios that most thinking people would like to have demonstrated to them before they have to work it out for themselves. There is at least one pilot, who on his first solo had a real launch failure and was pleased he knew what to do. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Colin Collyer Sent: Thursday, 11 September 2008 10:15 AM To: Discussion of issues relating to Soaring in Australia.

The plane doesn't know how far it is above the ground.

Re: [Aus-soaring] Training Value of 400 to 500 AGL flight
As an instructor, I only ever pull the bung if I am absolutely confident that I can handle the emergency if the student/pilot-on-check stuffs up or takes a poor option I hope so!! --- On Mon, 8/9/08, Peter Stephenson [EMAIL PROTECTED] wrote: From: Peter Stephenson [EMAIL PROTECTED] Subject: Re: [Aus-soaring] Training Value of 400 to 500 AGL flight To: Discussion of issues relating to Soaring in Australia. aus-soaring@lists.internode.on.net Received: Monday, 8 September, 2008, 4:53 PM I agree with MT as well. As an instructor, I only ever pull the bung if I am absolutely confident that I can handle the emergency if the student/pilot-on-check stuffs up or takes a poor option. My hand is almost on the stick to prevent an error. It is never below 300' AGL unless I can land ahead. Prior to being an instructor, I was always disappointed when the annual check instructor did *not* pull a low level release because I was confident that I could do them but was never tested.
