Abstract:
An adjustable mounting tray for installation of an aircraft gyroscopic and/or inertial reference apparatus, comprises, a baseplate member mounted so that it is substantially level in roll and pitch on the equipment shelf or rack of a levelled aircraft. A top plate or tray member is pivotally mounted on the baseplate for azimuthal adjustment thereon. The aircraft is pitched up or down and the top plate rotated in azimuth to remove any roll/yaw cross-axis coupling thereby assuring precision longitudinal axis alignment.
