gyroscopic Flashcards
what are the gyroscopic instruments
attitude, heading indicator, & turn coordinator
what are the two principles of a gyroscope
rigidity in space & precession
what is rigidity in space
it is the principle that a gyroscope will stay upright and continue to spin if it is in a vacuum
what is precession
a disk is spinning and when it is hit, the force of that hit will be felt 90° around the disk
what is the attitude indicator
shows BANK and PITCH
what principal does the attitude indicator operate on
rigidity in space
how long after starting the engine should the attitude indicator show correct attitude
5 minutes
gyros are vacuum driven in steam gauge but what does it use in the mga archers
MEMS
Micro
Electro
Mechanical
System
what are the errors of the attitude indicator
small accel/decel errors
- accel = slight pitch up
- decel = slight pitch down
rollout error
- following a 180 turn shows a slight turn in the opposite direction
what principle does the heading indicator operate on
rigidity in space
what does the turn indicator include
turn COORDINATOR
turn-AND-SLIP
what principle does the turn indicator operate on
precession
what does the turn COORDINATOR show
rate of turn AND rate of roll
what does the turn-and-SLIP indicators show
rate of TURN
