Hm, well, the Aerodynamics for Naval Aviators" was a bit over my
head at the time and the instrument flying one was a bit confusing
with the pics of giants holding up the wings of Wildcats!

I read through it for the first time (prior I had picked my way
through) while watching the NFC and AFC playoffs this Sunday. It
was the perfect 10 minutes at a time read -- more than that and it
was just too much info to process.

Most was a review of things I had read elsewhere, but written in a
much more succinct and authoritative manner.

The landing performance section confirmed earlier posts about
arriving at the runway with minimal energy -- 1.3-1.5 Vso.

Seems as if this rule would be doubly critical to conventional
gear.

Well, yeah, becase you generaly three point them anyway, arriving
with any more than that just extends your flare. It's not what I'd
call critical, more pointless.

Bertie

Well, isn't it critical in the sense that excess speed increases the
possibility of a ground loop?


ell, not if you land three point. If you land three point the speed is
pretty much always exactly the same for a given weight. For a wheel
landing, though, you'd be correct, if the wheel landing was done by
driving the airplane onto the ground, which would be poor technique. A
wheel lnding should also be made in the same attitude each tie and that
will give you the same touchdown speed eahc time regardless of the
approach speed. You will float, though!


Bertie

you can improve on that.

the secret to a successful landing is to have the longitudinal axis of
the aircraft aligned in the direction of flight, to have no sideslip,
to have no vertical speed at the point of touchdown and to have no
excess of speed.

if you have any excess of speed and some vertical speed on touchdown,
unless your tyres are pretty flat, you'll bounce back into the air in
a balloon. guaranteed.

speed does not increase the possibility of a groundloop if the
aircraft is kept aligned with the direction of flight.
