FAA Private Pilot Practice Test

Why is frost considered hazardous to flight?

Frost changes the basic aerodynamic shape of the airfoils, thereby increasing lift.

Frost slows the airflow over the airfoils, thereby increasing control effectiveness.

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

Correct! Wrong!

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

decrease as the true airspeed decreases.

decrease as the true airspeed increases.

remain the same regardless of altitude.

Correct! Wrong!

What is the purpose of the rudder on an airplane?

To control yaw.

To control overbanking tendency.

To control roll.

Correct! Wrong!

What is one purpose of wing flaps?

To enable the pilot to make steeper approaches to a landing without increasing the airspeed.

To relieve the pilot of maintaining continuous pressure on the controls.

To decrease wing area to vary the lift.

Correct! Wrong!

What does the red line on an airspeed indicator represent?

Maneuvering speed.

Turbulent or rough-air speed.

Never-exceed speed.

Correct! Wrong!

Loading an airplane to the most aft CG will cause the airplane to be

less stable at all speeds.

less stable at slow speeds, but more stable at high speeds.

less stable at high speeds, but more stable at low speeds.

Correct! Wrong!

Changes in the center of pressure of a wing affect the aircraft’s

lift/drag ratio.

lifting capacity.

aerodynamic balance and controllability.

Correct! Wrong!

What is ground effect?

The result of the interference of the surface of the Earth with the airflow patterns about an airplane.

The result of an alteration in airflow patterns increasing induced drag about the wings of an airplane.

The result of the disruption of the airflow patterns about the wings of an airplane to the point where the wings will no longer support the airplane in flight.

Correct! Wrong!

Which color identifies the normal flap operating range?

The lower limit of the white arc to the upper limit of the green arc.

The green arc.

The white arc.

Correct! Wrong!

Upon encountering severe turbulence, which flight condition should the pilot attempt to maintain?

Constant altitude and airspeed.

Constant angle of attack.

Level flight attitude.

Correct! Wrong!

The maximum speed at which the airplane can be operated in smooth air is

100 KTS.

165 KTS.

208 KTS.

Correct! Wrong!

When are the four forces that act on an airplane in equilibrium?

During unaccelerated flight.

When the aircraft is accelerating.

When the aircraft is at rest on the ground.

Correct! Wrong!

When landing behind a large aircraft, which procedure should be followed for vortex avoidance?

Stay above its final approach flightpath all the way to touchdown.

Stay below and to one side of its final approach flightpath.

Stay well below its final approach flightpath and land at least 2,000 feet behind.

Correct! Wrong!

Wingtip vortices are created only when an aircraft is

operating at high airspeeds.

heavily loaded.

developing lift.

Correct! Wrong!

After takeoff, which airspeed would the pilot use to gain the most altitude in a given period of time?

VY.

VX.

VA.

Correct! Wrong!

Which statement relates to Bernoulli's principle?

For every action there is an equal and opposite reaction.

An additional upward force is generated as the lower surface of the wing deflects air downward.

Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface.

Correct! Wrong!

If an airplane weighs 4,500 pounds, what approximate weight would the airplane structure be required to support during a 45° banked turn while maintaining altitude?

4,500 pounds.

6,300 pounds.

7,200 pounds.

Correct! Wrong!

VNO is defined as the

normal operating range.

never-exceed speed.

maximum structural cruising speed.

Correct! Wrong!

VNO is the maximum structural cruising speed (airspeed indicator upper green arc limit). VNO should only be exceeded in smooth air. FAR 1.2. Answer A is incorrect because the normal operating range is indicated by the entire green arc on the airspeed indicator. Answer B is incorrect because the never-exceed speed is VNE, (the red radial line on the airspeed indicator).

Which V-speed represents maximum landing gear extended speed?

VLE.

VLO.

VFE.

Correct! Wrong!

VSO is defined as the

stalling speed or minimum steady flight speed in the landing configuration.

stalling speed or minimum steady flight speed in a specified configuration.

stalling speed or minimum takeoff safety speed.

Correct! Wrong!
