Can anyone, anywhere, tell me how to contact the owner of a Diamont

Kurragong Drive in Alice Springs. Any details on the owner or the

That's interesting.
Pete,
It's no myth, but it can be subtle and shows-up most strongly at high power
and angle-of-attack (eg final approach.)
If you think of a lift/drag curve, there is a hump in the centre. So there
is usually two points on the curve which correspond to the lift you need,
one at low AoA (and low
Andrew
GFA extracts a modest fee for each Form 2 that's completed. Presumably
amongst the paperwork sent to the GFA are the details of the owner and
inspector. Suggest you give GFA a call.
Otherwise, a call to the Club secretary / president of Alice Springs Gliding
Club may reveal some furth
The fact that there are two points on the curve with the same lift isn't my idea of
hysteresis. To get hysteresis, as used in electronics, the whole curve would have to
shift depending upon whether the plane reached a point on the curve by slowing the
plane to that speed or by increasing the pl
Thanks Jason.
You are quite right. I got in contact with Mike Valentine at the
GFA and he had the answers to all my question. "Problem solvered"
PS Once again the GFA has come to the rescue. In every dealing
I have with the GFA I am very impressed with the level of service I get

Stephen,
I'd have to look at some curves to confirm the mechanism, but there is
definitely a "step" at cruising speeds.
In a C172 at cruise power (23" from memory) you'll get at around 100k when
you've got things right - and about 95k if not. I was trained to check the
airspeed and push the nose
