B.
Each of the tests can be done separately as necessary to do an operational check of that part of the system. All of the tests can be done to do a complete operational check of the system.
C.
It is necessary to operate test switches on the Antiskid/Autobrake Control Unit (M102) in the Main Equipment Center to do this test. You can get access to the control unit through the electronics access door, 119AL (AMM 06-41-00).
D.
These indicator lights and EICAS displays give fault indications for the system:
(1)
An ANTISKID light on the pilot's overhead panel P5.
(2)
An AUTOBRAKES light on the pilot's center instrument panel (P1-3).
(3)
Two EICAS display units on panel P2 to give the caution and advisory message, and the status and maintenance formats.
