Question: 3201 Subject Code: H300
The four forces acting on an airplane in flight are
A) lift, gravity, power, and friction.
B) lift, weight, thrust, and drag.
C) lift, weight, gravity, and thrust.

Question: 3202 Subject Code: H300
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.

Question: 3203 Subject Code: H300
(Refer to figure 1.) The acute angle A is the angle of
A) attack.
B) dihedral.
C) incidence.

Question: 3204 Subject Code: H300
The term "angle of attack'' is defined as the angle
A) between the wing chord line and the relative wind.
B) between the airplane's climb angle and the horizon.
C) formed by the longitudinal axis of the airplane and the chord line of the wing.

Question: 3205 Subject Code: H300
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.

Question: 3206 Subject Code: H300
How will frost on the wings of an airplane affect takeoff performance?
A) Frost will change the camber of the wing, increasing its lifting capability.
B) Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability.
C) Frost will cause the airplane to become airborne with a higher angle of attack, decreasing the stall speed.

Question: 3207 Subject Code: H300
In what flight condition is torque effect the greatest in a single-engine airplane?
A) High airspeed, high power, high angle of attack.
B) Low airspeed, low power, low angle of attack.
C) Low airspeed, high power, high angle of attack.

Question: 3824 Subject Code: J27
Wingtip vortices are created only when an aircraft is
A) operating at high airspeeds.
B) developing lift.
C) heavily loaded.

Question: 3825 Subject Code: J27
The greatest vortex strength occurs when the generating aircraft is
A) heavy, dirty, and fast.
B) light, dirty, and fast.
C) heavy, clean, and slow.

Question: 3826 Subject Code: J27
Wingtip vortices created by large aircraft tend to
A) rise into the traffic pattern.
B) rise into the takeoff or landing path of a crossing runway.
C) sink below the aircraft generating turbulence.

Question: 3827 Subject Code: J27
When taking off or landing at an airport where heavy aircraft are operating, one should be particularly alert to the hazards of wingtip vortices because this turbulence tends to
A) rise into the traffic pattern area surrounding the airport.
B) sink into the flightpath of aircraft operating below the aircraft generating the turbulence.
C) rise from a crossing runway into the takeoff or landing path.

Question: 3828 Subject Code: J27
The wind condition that requires maximum caution when avoiding wake turbulence on landing is a
A) light, quartering tailwind.
B) strong headwind.
C) light, quartering headwind.

Question: 3829 Subject Code: J27
When landing behind a large aircraft, the pilot should avoid wake turbulence by staying
A) above the large aircraft's final approach path and landing beyond the large aircraft's touchdown point.
B) below the large aircraft's final approach path and landing before the large aircraft's touchdown point.
C) above the large aircraft's final approach path and landing before the large aircraft's touchdown point.

Question: 3830 Subject Code: J27
When departing behind a heavy aircraft, the pilot should avoid wake turbulence by maneuvering the aircraft
A) above and upwind from the heavy aircraft.
B) below and upwind from the heavy aircraft.
C) below and downwind from the heavy aircraft.
