The TFR in the TSR 2 was unique to that aircraft
at that time in that it would automatically fly the aircraft via autopilot at a set height above ground. I think a later version was fitted to Tornado GR1/4.
The radar in the F111 was 'terrain avoidance' not 'terrain following'; it would warn the pilot of reduced vertical separation from the surface and the pilot then had to take action to correct.
