 FLAPS ELECTRICAL CONTROL AND MONITORING - DESCRIPTION AND OPERATION
___________________________________________________________________
 1. General_______
 The electrical control and monitoring system of the flaps has:
 -
a manually operated slat/flap control lever

 -
a Command Sensor Unit (CSU) 51CV

 -
two Slat and Flap Control Computers (SFCC1 and SFCC2) 21CV, 22CV

 -
two electrically controlled valve blocks 23CV(24CV) installed on the flaps Power Control Unit (PCU) 6201CM (Ref. 27-54-00)

 -a Feedback Position Pick-Off Unit (FPPU) 27CV
 -
two Asymmetry Position Pick-Off Units (APPU) 29CV(30CV)

 -
two Wing Tip Brakes (WTB) 33CV(34CV)

 -
two flap interconnecting struts, each with two flap-attachment failure detection sensors 37CV, 39CV (38CV, 40CV).

 The functions of the flaps electrical control and monitoring system are:
 -
to control the valve blocks electrically

 -
to control the WTBs electrically

 -
to receive data from and send data to the related systems

 -
to monitor the power transmission for correct operation

 -
to monitor the control system and power transmission for component failure
