-TEST
R (Ref. Fig. 012) This function is to be activated after any maintenance action on the aircraft. Its purpose is to re-configure the BSCU (if necessary) and to check its correct operation and the continuity with the different peripherals. Its system is separately actuated. The test control must trigger: *the power-up test of the system concerned *the peripheral continuity test (permanent monitoring and specific test for the ALTERNATE and NWS servovalves, through transmission and check of calibrated currents).
-PIN PROG SELECTION
R (Ref. Fig. 009) This function is to be performed after removal/installation of the BSCU. Its purpose is to adapt the BSCU pin programming to the aircraft pin programming (strap connection). At the end of the Menu mode, the system must be set to OFF then to ON to be correctly reset. Moreover, the pin programming selection must also be performed on the second BSCU system. The various configurations available depend on the parameters below: . aircraft type, . brake type, . wheel type (different diameters), . deceleration rate in special automatic braking mode.
-STEERING DATA (Ref. Fig. 013) The purpose of this function is to present the main parameters of the nose wheel steering system. The parameters are: . SELV ORDER: Nose Wheel Steering (NWS) electro-distributor status (OPEN or CLOSED), . SSV CURRENT: NWS servovalve current (-10 mA < SSV CURRENT < +10 mA), . STEER ORDER: Commanded steering angle (-75 deg. < STEER ORDER < +75 deg.), . CAPT ANGLE: CAPT steering handwheel angle (-75 deg. < CAPT ANGLE < +75 deg.), . FO ANGLE: F/O steering handwheel angle (-75 deg. < FO ANGLE < +75 deg.), . PEDAL ANGLE: ELAC angle (-75 deg. < PEDAL ANGLE < +75 deg.),
