What is the primary function of the flux gate system in an aircraft?
To continuously sense the earth's magnetic field
What is the benefit of slaved gyros in an aircraft?
They reduce pilot workload by eliminating the need for manual realignment

To process the gyro unit until it is aligned with the transmitter signal
What is the purpose of the magnetic slaving transmitter in an aircraft?
To amplify the signal from the flux gate system
What is the trend in instrument panel design?
To combine instruments to reduce pilot workload
What is the primary function of the Directional Gyro (DG) in an aircraft?
To provide a visual display of the aircraft's heading
What is the primary function of the gyroscope in a Horizontal Situational Indicator?
To establish an inertial platform that remains fixed in space
What is the purpose of the knob on the front of the Horizontal Situational Indicator?
To engage the gimbals and allow the pitot to rotate the gyro and card
What is the term for when the gyro in a Horizontal Situational Indicator becomes distributed and needs to find its axis again?
Tumble indicator
How is the gyroscope in a Horizontal Situational Indicator typically powered?
All of the above
What is the name of the line on the Horizontal Situational Indicator that the number opposite it must agree with the magnetic compass?
Lubber line
In what type of flight profile is the tumble indicator most likely to occur?
Aerobatic flight
What is the primary purpose of a heading indicator in an aircraft?
To aid the pilot in navigation by determining aircraft direction
What is the difference between True North and Magnetic North?
True North is based on the North Pole, while Magnetic North is based on the Earth's magnetic field
What is the main advantage of gyroscopic heading indicators over magnetic compasses?
Gyroscopic heading indicators are more reliable and less prone to errors
What is the purpose of a self-erecting mechanism in a gyroscope?
To apply a precessing force to the gyroscope
Why do gyro heading indicators need to be manually set to the appropriate heading?
Because they are not north-seeking
What is the significance of the gimbal system in gyroscopic heading indicators?
It allows the gyroscope to rotate freely about the vertical axis
