Roll Stabilization Inoperative - Honeywell Primus 880 Pilot's Manual

PRIMUSr 880 Digital Weather Radar System
In prolonged turns, gyro precession can occur that is tracked by the
stabilization system and appears as undesirable ground targets on the
indicator. For example, a 1°precession error (which would probably not
be noticed on the gyro horizon) moves the antenna beam
approximately 10,500 feet at a point 100 NM from the aircraft, If ground
targets between 50 and 80 NM depending on aircraft altitude and the
actual setting of the tilt control.
