C) formed by the longitudinal axis of the airplane and the chord line of the wing. 6 H910 PVT (Refer to figure 1.) The acute angle A is the angle of A) incidence. B) attack. C) dihedral. 7 H912 PVT 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. B) Lift, drag, and weight equal thrust. C) Lift and weight equal thrust and drag. 8 H911 PVT When are the four forces that act on an airplane in equilibrium? A) During unaccelerated flight. B) When the aircraft is accelerating. C) When the aircraft is at rest on the ground. 9 H911 PVT The four forces acting on an airplane in flight are A) lift, weight, thrust, and drag. B) lift, weight, gravity, and thrust. C) lift, gravity, power, and friction. 10 H951 PVT How will frost on the wings of an airplane affect takeoff performance? A) Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability. B) Frost will change the camber of the wing, increasing its lifting capability. C) Frost will cause the airplane to become airborne with a higher angle of attack, decreasing the stall speed. 11 H911 PVT What force makes an airplane turn? A) The horizontal component of lift. B) The vertical component of lift. C) Centrifugal force. 12 H573 PVT VFR approaches to land at night should be accomplished A) at a higher airspeed. B) with a steeper descent. C) the same as during daytime. 13 H920 PVT In what flight condition is torque effect the greatest in a single-engine airplane? A) Low airspeed, high power, high angle of attack. B) Low airspeed, low power, low angle of attack. C) High airspeed, high power, high angle of attack. 14 H920 PVT The left turning tendency of an airplane caused by P-factor is the result of the A) clockwise rotation of the engine and the propeller turning the airplane counter-clockwise. B) propeller blade descending on the right, producing more thrust than the ascending blade on the left. C) gyroscopic forces applied to the rotating propeller blades acting 90�‹ in advance of the point the force was applied. 15 H920 PVT When does P-factor cause the airplane to yaw to the left? A) When at low angles of attack. B) When at high angles of attack. C) When at high airspeeds. 16 H917 PVT What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted? A) The CG shifts forward when thrust and drag are reduced. B) The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced. C) When thrust is reduced to less than weight, lift is also reduced and the wings can no longer support the weight. 17 H917 PVT What determines the longitudinal stability of an airplane? A) The location of the CG with respect to the center of lift. B) The effectiveness of the horizontal stabilizer, rudder, and rudder trim tab. C) The relationship of thrust and lift to weight and drag. 18 H917 PVT An airplane said to be inherently stable will A) be difficult to stall. B) require less effort to control.
