The Buccaneer Pilot's Display Unit was an element of the Strike Sight System; the weapon aiming and release system. The PDU was aligned to the aircraft axes using an alignment telescope which was sighted on a remote target board. The aircraft was levelled and the alignment offset read from an elevation and azimuth vernier. The Test Equipment was initially only intended to have one 1st and one 2nd Line Test Set. Every 1st Line Test Set was weather sealed in a cast aluminium box with "scupper holes" so that any water that might land on it would drain away. Each of the units was put through a dunking test to ensure that it was watertight.
Another alignment Fixture is also described in "The Avionics Story: The Buccaneer S2, RN and RAF" by Alex W Duncan. This is called the Periscope Strike Sight Alignment Jig. This unit was designed to fit onto the three alignment spigots that located the Nose Section of the Aircraft when it was brought back into line. It carried two Collimators, the upper was used to align the Head-Up Display the Aircraft Centreline, and the lower to align the Strike Sight Gyro Unit.
