GPC - Glider Pilot Certificate Aircraft Systems and Instruments Questions and Answers

Question 1

A glider's pitot-static system provides data for which combination of instruments?

Accepted Answer

Airspeed indicator, altimeter, and vertical speed indicator (variometer)

Answer

Airspeed indicator, compass, and variometer

Answer

Altimeter, attitude indicator, and airspeed indicator

Answer

Vertical speed indicator, yaw string, and altimeter

Question 2

During a pre-flight inspection, you notice the yaw string is frayed and partially detached. What is the primary consequence of flying with a malfunctioning yaw string?

Accepted Answer

Difficulty in maintaining coordinated flight.

Answer

Inaccurate airspeed readings during turns.

Answer

Incorrect altitude indications in windy conditions.

Answer

The variometer will show a constant climb.

Question 3

What is the primary function of a total energy compensated variometer?

Accepted Answer

To indicate the rate of climb or descent due only to the movement of the surrounding air mass.

Answer

To show the glider's vertical speed relative to the ground.

Answer

To measure the potential energy of the glider based on its altitude.

Answer

To provide an audible warning of excessive airspeed.

Question 4

A pilot in a glider without flaps or a retractable undercarriage needs to significantly increase the rate of descent without a corresponding increase in airspeed. Which control system should be used?

Accepted Answer

Spoilers/Air Brakes

Answer

Rudder

Answer

Ailerons

Answer

Elevator

Question 5

While performing a coordinated right turn in a glider, how are the primary flight controls manipulated?

Accepted Answer

Stick moves right, right rudder pedal is pressed.

Answer

Stick moves right, left rudder pedal is pressed.

Answer

Stick moves left, right rudder pedal is pressed.

Answer

Stick moves back, right rudder pedal is pressed.

Question 6

If the static port on a glider becomes blocked during flight, how will the altimeter and airspeed indicator be affected?

Accepted Answer

The altimeter will freeze at the altitude where the blockage occurred, and the airspeed indicator will be inaccurate.

Answer

The altimeter will be unaffected, but the airspeed indicator will read zero.

Answer

Both instruments will read zero.

Answer

The altimeter will indicate a continuous climb, and the airspeed indicator will read higher than actual.
