(forward)


Drag (Backwards)


Lift (Up)


Weight (Down)

unaccelerated flight


What is the relationship between the forces on an airplane? - ANSWER✔✔-thrust =

drag


lift = weight


Bernouli's Law/Principle - ANSWER✔✔-Air travels faster over curved upper surface

which causes lower pressure on the top of the surface (high pressure under the wing,

low pressure above the wing)

, Critical Angle of attack - ANSWER✔✔-The angle of attack at which an airfoil stalls

(loses lift) regardless of the aircraft's airspeed, attitude, or weight.


Angle of attack - ANSWER✔✔-"Acute angle A"


the angle between the chord line of the wing and relative wind


As altitude increases, the indicated airspeed at which a given airplane stalls in a

particular configuration will - ANSWER✔✔-remain the same regardless of altitude


The angle of attack at which an airplane wing stalls will - ANSWER✔✔-remain the

same regardless of weight


In what flight condition must an aircraft be placed in order to spin? - ANSWER✔✔-

stalled (Both wings must be stalled)


During a spin to the left, which wing(s) is/are stalled - ANSWER✔✔-both wings are

stalled


How will frost on the wings of an aircraft takeoff performance? - ANSWER✔✔-Frost

will disrupt the smooth flow of air over the wing, adversely affecting its lifting

capabilities


Why is frost considered hazardous to flight? - ANSWER✔✔-Frost spoils the smooth

flow of air over the wings, thereby decreasing lifting capability.


How does frost affect the lifting surfaces of an airplane on takeoff? - ANSWER✔✔-Frost

may prevent the airplane from becoming airborne at normal takeoff speed
