nother way of looking at air racing - to go fast you need to reduce
LIFT to the absolute minimum required to keep the plane at the desired
altitude - so the LIFT REQUIRED is only the weight of the plane. The
lift PRODUCED increases dramatically with airspeed.


Clare... (sigh...) When, exactly, did you encounter any situation in
straight and level flight were one needed more lift than the weight of
the plane (or less)?

Level flight _describes_ a situation where lift is equal to weight.

It doesn't matter what speed range you're considering... you don't
"reduce lift" to fly level, you keep it constant.


Yes, but lift increases with airspeed - to a point - and if trimmed
for level flight at X000 feet at , say 300 mph, if you do not change
trim you will NOT be at X000 feet at 500MPH

The only part of what you said that made any sense at all was that you
may have to reduce the angle of attack to keep the lift constant at
higher speeds.

Hey LLoyd - what part of "so the LIFT REQUIRED is only the weight of
the plane. The lift PRODUCED increases dramatically with airspeed."
didn't you catch? You increase speed, you increase lift - so as you
speed up you need to - get this - REDUCE LIFT - to stay at the same
level.
