Pedal Shaker Assembly
Modification Record 1
The shaker's 1.65m screened cable is included in its weight but excluded from its size.
The year of manufacture is based on the date of EAP's first flight.
This Unit is part of the Flight Control system and is put into operation when the onset of a stall is detected. The system uses the Angle of Attack Transmitter mounted on the nose and other inputs such as gear and flap position and when it senses an impending stall it will activate the Shaker. The Shaker is an electric motor with an eccentric or cam built in that causes it to vibrate rather coarsely. On the EAP the Shaker is attached to one Rudder Pedal to provide the pilot with a physical warning that the aircraft is approaching a stall.
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.
