barit1,

Thanks for understanding my poor aviationese.

Consider this then:

The helo can fly horizontally (IAS) at altitudes HIGHER than it can hover (at a given weight, conditions, etc). So when the helo is moving, why does it get extra lift???

This is what I've trying to figure out.

One physics instructor told me that it had to do with heat in the air, something about "adibatic (?) and Pascal."

Hmmm, can anybody tell me if two identical aircraft in identical conditions (weight, alt, etc etc) EXCEPT for temp, does the one in colder air require more pitch up to maintain altitude????
