4. What is the full form of VFR?
a) Visual flight rules
b) Visual flying rules
c) Virtual flight rules
d) Virtual flying rules

Answer: a
Explanation: VFR refers to Visual flight rules. These are a set of rules that a pilot operates under so as to fly the aircraft in generally clear weather conditions.

5. By correcting the indicated airspeed for nonstandard temperature and pressure, we obtain ___________ airspeed.
a) Actual
b) Virtual
c) True
d) Relative

Answer: c
Explanation: By correcting the indicated airspeed for nonstandard temperature and pressure, we obtain true airspeed. True airspeed may also be referred to as TAS.

6. What is the frequency at which aircraft equipment’s operate?
a) 350Hz
b) 450Hz
c) 400Hz
d) 40Hz

Answer: c
Explanation: Aircraft equipment’s operate at 400Hz. They operate at high frequency in order to reduce the core size of equipment’s used.

7. What is the full form of IAS?
a) Implied airspeed
b) Indicated airspeed
c) Incident airspeed
d) Immediate airspeed

Answer: b
Explanation: IAS refers to Indicated airspeed. It is the airspeed that is read directly from the airspeed indicator on an aircraft. The indicator is located on the instrument panel.

8. What does the attitude indicator display?
a) Aircraft’s relation to the horizon
b) Aircraft’s relation to the ground
c) Aircraft’s relation to the wind flow
d) Aircraft’s relation to the atmospheric pressure

Answer: a
Explanation: The attitude indicator displays the aircraft’s relation to the horizon. It is a primary aircraft instrument and is also useful in conditions of poor visibility.

9. TAS shows airspeed in ___________
a) Miles per hour
b) Knots
c) Nautical miles
d) Kilometer per hour

Answer: b
Explanation: TAS shows airspeed in knots. The airspeed is usually in the range from 200 knots and higher, and is the actual air speed of an aircraft, in accordance with external conditions.

10. The compass instrument shows the aircraft’s heading relative to magnetic ___________
a) West
b) North
c) South
d) East

Answer: b
Explanation: The compass instrument shows the aircraft’s heading relative to its magnetic north. The accumulated errors in the instrument include the actual difference present between magnetic direction and true direction.
