The two fundamental properties of gyroscopes are?
Rigidity - Property to resist any force tending to change the plane of rotation of its rotor
Precession - Angular change in direction of the plane of rotation under the influence of an applied force
The rigidity of the gyroscope is affected by?
Its rotational speed, rotor mass, and gyration radius
An Altimeter is more sensitive when it responds to?
1000 ft of change in one revolution of its dial
A resistance thermometer uses Nickel for measuring temperatures up to ____ and platinum for up to _____
Uses Nickel for measuring temperatures up to 300C, and uses Platinum for up to 600C
he Shock Mount is used to _______ of the main instrument panels
Reduce vibration
Why are Instruments sealed in Nitrogen and Helium?
Inert gases which protect instruments from atmospheric effects
