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.

 I believe that there is some training value in such a flight:

 The ability to fly and manoevure confidently at low level without getting
ground fright. (i.e. if I had the option to do a low level circuit for a
safe landing on field after a rope break, that would my first option).

 Also low level flight is experience with ridge flying too.

 Also in still wind conditions, a 180 degree turn can be considered.

 Such manoevures need to be demonstrated at altitude, i.e. demonstrate a
180 degree change of heading with minimum height loss, in a Grob G103,
banked at 60 degrees,  60 knots airspeed, in still air, height loss in a 180
degree turn is 150', with a diameter of the turn of 120m

 Obviously needs to be done with a proper briefing, exercise at altitude,
exercise at 400' to 500' AGL, post flight de-brief.

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

  If the GFA accepts, mandates, hints at or even vaguely accepts that 60 degree 
banks at low level/half circuit height are the way to go when turning back from 
a rope break, I predict that the accident rate will soar (pardon the pun) with 
spiralling-in being the new buzzword  and more than half of 'em

rise, so it won't all be bad.

Re: [Aus-soaring] Training Value of 400 to 500 AGL flight: for avery rare reality...

2008-09-11 Thread Gary Stevenson

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.

Regards,
Gary

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.

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.

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.

To be subjective, the maths need to be done  AT 400ft and counting !!

 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.
 
 I will do the maths for it.

Further to this email, I have just remembered the last quite 
experienced pilot that I pulled the bung on at 400'.  He attempted to 
turn with the nose above the horizon which I stopped, and then 
proceeeded to become indecisive and I had to take over as the option 
he was going to take could have put us into the fence at the end of 
the cross-strip.  His pre-take-off checks were impeccable but when it 
came to the real thing, he was out of his depth.


At the subsequent de-briefing when I asked him why he was going to 
turn with the nose above the horizon,  he said: but we had 60 knots 
on the clock!.  He had forgotten about inertia and airspeed 
indicator lag and that a steep turn in a climbing vector can quickly 
become a stall turn if not executed precisely. The last time he had 
performed a low level rope break was seven (7) years previously.


We had another normal check flight that he passed, and he thanked 
me for waking him up from his complacency.


PeterS



Well then again maybe he had a plan which you stuffed up. I'd have 
told you to fly the damn thing yourself. Maybe he just went along to 
get along and you are delusional.


Mike

No he did not have a plan as I asked him more than twice what he was 
planning to do and only when I was out of my comfort zone did I take over.

[Aus-soaring] Training Value of 400 to 500 AGL flight

2008-09-10 Thread Geoff Kidd
If the GFA accepts, mandates, hints at or even vaguely accepts that 60 degree 
banks at low level/half circuit height are the way to go when turning back from 
a rope break, I predict that the accident rate will soar (pardon the pun) with 
spiralling-in being the new buzzword  and more than half of 'em 
will be Instructors ... but the value of any in-tact sailplanes will 
rise, so it won't all be bad.___

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.  I have had an AEI 
ask to practice a 300' release in a strong wind, as he felt the same.


Recently at Caboolture we had a power pilot who lost power on take off  
at a very low height and he just pushed the nose forward and pancaked 
his beautifully restored aircraft. Obviously he had a habit of hanging 
on the prop on take off and learned the hard way.

I believe that there is some training value in such a flight:

The ability to fly and manoevure confidently at low level without getting 
ground fright. (i.e. if I had the option to do a low level circuit for a safe 
landing on field after a rope break, that would my first option).

Also low level flight is experience with ridge flying too.

Also in still wind conditions, a 180 degree turn can be considered.

Such manoevures need to be demonstrated at altitude, i.e. demonstrate a 180 
degree change of heading with minimum height loss, in a Grob G103, banked at 60 
degrees,  60 knots airspeed, in still air, height loss in a 180 degree turn is 
150', with a diameter of the turn of 120m

Obviously needs to be done with a proper briefing, exercise at altitude,  
exercise at 400' to 500' AGL, post flight de-brief.

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