1.2 aerodynamic forces Flashcards
1
Q
the four forces acting on an airplane in flight are
A
lift, weight, thrust, and drag
2
Q
when are the four forces that act on an airplane in equilibrium
A
during unaccelerated level flight
3
Q
what is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight
A
lift equals weight and thrust equals drag
4
Q
which statement relates to Bernoulli’s principle
A
air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface
