The gyrocompass error resulting from your vessel’s movement in OTHER than an east-west direction is called().
A、damping error
B、ballistic deflection
C、quadrantal error
D、speed error
A、damping error
B、ballistic deflection
C、quadrantal error
D、speed error
A、accurate only in the Polar regions B、accurate electronic servomechanisms C、hand operated D、accurate only if the vessel is underway

A、A.The readings are too low (small numerically) and the amount of the error must be added to the compass to obtain true B、B.The readings are too low and the amount of the error must be subtracted from the compass to obtain true C、C.The readings are too high (large numerically) and the amount of the error must be added to the compass to obtain true D、D.The readings are too high and the amount of the error must be subtracted from the compass to obtain true
