Notes:

EAP stands for "Experimental Aircraft Programme and was a technology demonstrator for what was to become the Eurofighter Typhoon. The sole aircraft (serial ZF534) first flew on 8 August 1986. The EAP aircraft was retired from service on 1 May 1991 and was then sent to the Aeronautical and Automotive Engineering department of Loughborough University but as of April 2012 it has been moved to the Royal Air Force Museum Cosford.
Marconi Avionics, in common with other suppliers, made equipment for the EAP at their own cost in anticipation of orders for the Typhoon. Around 6 to 8 sets of equipment were made and all were put through the full evaluation/qualification tests.
The Pilot’s Control Unit (PCU) drives into the Flight Control Computer and has a number of control functions which are marked slightly differently on the three units held.
‘Test and Reset’
‘Take-off Trim’ setting
‘Up/Down’ On the Unit Cat Nos. C0146 and C0147 this is marked as ‘Throttle Increment/Decrement’
‘Droop Lock/Unlock’
‘Emergency Trim’
‘Reversionary/Full/Reversionary’. This is a pull-to-turn switch. On the unit C0147 this is marked ‘Heavy/Medium/Light’
‘Yaw Trim’
‘Lift Dump/Off’

This unit is Ser. No. 001 and was the Qualification test unit hence the red banding ‘Not for Flight’ the controls are marked slightly differently from C0147 and C0910
