Hi All,


Imagine a plane in 2 conditions.


1) Climbing with full power
2) Descending fast with 50% power.


Waitaminute - how can a plane be in both conditions at the same
time!?


Both have constant rates of ascent and descent.


But are they the same rates or different?
What are the angles of attack on the wings in both cases?
What are the indicated airspeeds - the same or different?


Question A: Which wing is closer to stall?


The left one. I think. Except if it's a biplane and Tuesday, in which
case


it would be the red one.


Question B: A big updraft occurs, which is more likely to stall?


The one whose condition was closer to stall.
;-)


Aha, too deep for you eh? *:-P


Much too deep. But if you want a straight answer, I'd say a climbing plane
would be more likely to stall if a big updraft occurs. The plane's inertia
comes into play and causes the airflow to slow up over the wings (maybe
even reversing direction!?) coupled with the pilot's Hawaiian shirt all
conspire to cause the lift demons to depart. I least I think so.- Hide quoted text -


So, 1 vote for B1 and what about question A?

Cheers
