Revision - Gyro Instruments

What is the common name given to the airspeed indicator, altimeter, and vertical speed indicator?

• The static system

• The pressure trio

• The gyro pack

• The six pack

Which system do the attitude indicator, heading indicator, and turn coordinator use to give their readings?

• Pressure system

• Magnetic system

• Gyroscopic system

• Pitot-static system

What are the two main gyroscopic effects?

• Inertia and Momentum

• Rotation and Revolution

• Rigidity in space and Precession

• Centrifugal and Centripetal

What is directly proportional to the degree of rigidity of the gyroscope?

• The air pressure outside

• Its rotational speed or RPM and its moment of inertia

• Its weight

• The size of the gimbals

What type of gyro is used in the attitude indicator?

• Earth gyro

• Rate gyro

• Free gyro

• Tied gyro

How can gyroscopes in aviation be driven?

• By electricity or by air

• By hydraulic systems

• By solar power

• By manual winding

What is the main objective of having different systems to drive the gyro instruments in light aircraft?

• To reduce costs

• To save energy

• To increase accuracy

• To ensure redundancy

What happens to a gyro when it starts spinning?

• It consumes more power

• It stops moving

• It experiences gyroscopic effects

• It becomes lighter

What is the effect of precession in a gyro?

• It decreases the gyro's moment of inertia

• It increases the gyro's speed

• It stabilizes the gyro in space

• Any force applied is exerted at 90 degrees in the direction of rotation

What is the effect of a higher rotational speed on a gyro's precession?

• It has no effect on precession

• It makes the gyro more stable

• It increases the magnitude of precession

• It decreases the magnitude of precession
