What is used as a reference for range marking instruments?
Aircraft specification or TCDS and flight manuals
What does a yellow arc on an instrument dial indicate?
Caution
Why are slippage marks used on instrument glass covers?
To indicate glass rotation in the bezel
When range markings are placed on an instrument glass, what precaution must be taken?
The glass must be marked for slippage indication
What indication errors may be found in altimeters?
Scale errors, Hysteresis, friction, and Installation
What can be used to static check a manifold pressure indicator
Current atmospheric pressure

What methods are used to drive turn-and-bank/ slip indicators?
Vacuum, air pressure, and electricity
What causes an electric driven gyro rotor to tilt when the aircraft is turned?
Gyroscopic precession
What is a synchro type remote indicating system?
A system that transmits information from one point to another point.
