Yes, when it reaches the point where the pull of gravity is stronger than the engines' ability to lift it up. A plane is able to remain aloft because of Bernouli's principle:
Bernoulli's principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. ... The high air pressure underneath the wings will therefore push the aircraft up through the lower air pressure.
Geez L I never heard of that before! "Bernoulli's principle" eh? So if the wing shape were different the plane would not get the "lift" it needs? Now I'm trying hard to understand how it is possible for the air the plane goes through can flow "faster" over the top of the wing and "slower" underneath. My brain can't seem to get there L. But thank you for the excellent explanation.Do YOU understand the why? Sigh! :) ((hugs))
It's the same air above and below. Why there would be any difference between the two I don't understand. AARRGGHH! Anyway thank goodness I don't have to understand stuff to have it work. The world would be a terrible shape if it did rely on me "getting it"! Thank you for your reply L! :)
Too many variables to give a precise answer...Mass of the aircraft, type of aircraft (Commercial, military fighter, personal small aircraft, etc.), skill of the pilot, speed and angle of approach.
This reminds of replies I'd get from OLD SCHOOL. He'd always start out with "it's complicated" and then proceed to tell me why. Thank you for your reply E! :)
