The Tornado had a unit called the Throttle Box Control Quadrant located on the left console of the front cockpit. This unit has Throttle Controls for the two RB199 engines, a control for the Flaps and another for the Wing Sweep.
The Object in the Collection was used by Marconi-Elliott Avionic Systems Ltd when developing the Tornado RB199 Main Engine Control Unit (MECU). There may have been two such units one for each engine - mounted side by side.
The scale markings are ‘Idle’, ‘REHEAT, ARM’ & ‘COMBAT’ which are not fully those of the operational unit fitted namely ‘HP SHUT’ in the full aft position to ‘COMBAT’ in the full forward position, passing through ‘IDLE’, ‘MAX DRY’ and ‘MAX REHEAT’ positions. The -29° to +15° scale would imply the setting for the wing sweep angle but here again the actual lever selects wing sweep angles between 25 degrees (fully forward position) and 67 degrees (fully aft position).
The given height is with the lever upright.
