2 Q's on Remote Inidicating Compass
Would appreciate some comment on these two Q's which have gotten me confused. With regard to 1.(a) I am thinking 'Whatever keeps it horzontal' - but don't seem right.
Q1: Remote indicating compass: rotor of slaved gyro prevented from wandering:
a) In vertical plane by ... ?
b) In horizontal plane by .. ?
Q2: Notes I have contain phrase 'DG flag appears on Pilot's gyro unit'. What does the 'DG' stand for?
Many thanks in advance.
