Default Gentle take-offs at high speed

MX -

One of the things I think your theory is fundamentally neglecting is
the fact that most light GA aircraft cruise at a substantially lower
deck-angle than they sit on their wheels - this means if you try to do
anything near cruise speed while still on the ground, you'll be driving
your nosewheel into the ground whether or not your actively holding the
bird on the ground with elevator down pressure.

Vr exists for a reason... I was trained with the general consensus on
this board - begin pullback at VR, get the plane off the ground in
ground effect (you can clearly 'feel' the wheels leave the ground), and
then release the back-pressure until the aircraft accellerates to Vy
(or Vx, as the case may be) in ground effect, before setting up in a Vy
attitude climb.

Its interesting though - While most pilot's I talk too (including my
instructor) swear by this technique, I haven't seen much 'formal'
mention of it in the literature... It strikes me as being a cross
between a traditional and 'soft-field' takeoff. The FAA pilot's manual
warns that "premature rotation" can lead to settling back down on the
runway, and suggests a 'proper' takeoff is simply to set the Aircraft
in Vy attitude initially and let it fly off the runway, but my
instructor has warned me against becoming dependent on that technique,
especially if I ever hope to fly out of high DA airports...

I guess this is one of those areas where I'm still actively learning a
great deal.

Y'All,
To learn something that is basically incorrect presents TWO problems. If
this is the first way you learned to perform it will be your first selection
of options when under stress.

Secondly, the greatest single quality of knowing something that has
fundamental faults is that
unlearning such a fault is the most difficult part of you knowledge to
remove.

Learning to do something correctly FIRST is the most important part of all
performance.
Think on it,

I'm sure that pushing the stick forward works well. If there were no
way to keep a Baron on the ground at 100 kts, then no Baron could ever
crash at a speed of more than 100 kts, since its intense desire to fly
would keep it from contacting the ground.
