Notes:

The Tornado Navigator's main aid for updating the navigation system is CRPMD. This provides the facility to superimpose the ground mapping radar video on a moving map. The map is driven from the IN system and uses 35mm film. Three scales are available: 1 mile; ½ mile and ¼ mile. The map provides:-

● Normal present-position indication;
● North oriented display;
● Ground stabilized display;
● Look-ahead.

The unit was fitted to the rear cockpit of the Tornado, quite high on the glareshield in the centre. The CRPMD was made by Ferranti and it had initial system trials on Buccaneer XT272 in 1980 at Warton.
