LEADING EDGE AUTOSLAT SYSTEM - TROUBLE SHOOTING
_______________________________________________
1. General_______
A. This trouble shooting procedure uses the BITE feature of the stall management computer (SMC) to isolate faults in the stall warning system and the autoslat system. All interface with the BITE is through the maintenance control panel on the front of each SMC.
B. The SMC will allow entry into BITE only when one or both of these conditions exist:
(1)
Engines off. For SMC 1: Engine 1 N1 < 15%, Engine 2 N2 < 50% For SMC 2: Engine 2 N1 < 15%, Engine 1 N2 < 50%
(2)
Airspeed < 60 knots AND flaps fully retracted.
2. BITE Control and Display________________________
A. The maintenance control panel on the front of the SMC has two 8-character displays and 6 buttons for fault isolation and for checks during ground maintenance.
(1)
The ON/OFF button activates and deactivates the BITE feature. The All buttons on the SMC are normally inactive until the ON/OFF button is pushed to activate BITE.
(2)
The MENU button displays the current menu at any point in BITE. Pushing the MENU button interrupts any active test mode and returns to the most recently selected option of the current higher level menu.
(3)
The up arrow and down arrow buttons are used to sequence through the items under each menu.
(a)
If the up button is pushed when a list item or a menu option is shown, the previous item/option will be displayed.
NOTE:____ A list item does not have a question mark (?) at the end. A menu option has a question mark at the end.
______
(b)
If the up button is held down, approximately 4 items/options per second will be shown in sequence until the button is released or until the first item/option is shown; at this time the display will show BEGIN OF LIST.
