Q

if an airplane weighs 3,300 pounds what approximate weight would the airplane structure be required to support during a 30 degree banked turn while maintaining altitude
(load factor for 30 degree is 1.154)

A

3,300 x 1.154 =3,808.2

16
Q

why is frost considered hazardous to flight

A

frost spoils the smooth flow of air over the wings thereby decreasing lifting capabilities

17
Q

what determines the longitudinal stability of an airplane

A

the location of the CG with respect to the center of lift

18
Q

the what flight condition are torque effects more pronounced in a single engine airplane

A

low airspeed high power high angle of attack

19
Q

the left turning tendency of an airplane caused by p factor is the result of the

A

propeller blade descending on the right producing more thrust than the ascending blade on the left
