Notes:

The Pilot's Display Unit is boresighted to the aircraft axes to ensure that the symbology is accurately aligned over the real world. The process starts with a Master Reference tool which is a precision mirror machined to register with the installation bolts on an Alignment Jig. This reference is transferred to an Alignment tool and thence transferred to the actual PDU. The jigs are made of a stable alloy casting.
In recent years the alignment transfer is carried out with a high resolution Camera.
