B. Ground Tests
(1)
Ground tests provide a means of verifying and amplifying on flight faults to aid in fault isolation. Ground test also provide fault indications when no flight faults were recorded.
(a)
Tests 01 thru 16 are LRU tests oriented towards specific components.
(b)
Tests 30 and 40 are system tests involving the entire autoflight system.
(c)
Tests 51 thru 69 are supporting tests oriented towards specific function involving several components.
(2)
01 FCC (Left, Right, and Center)
(a) Displays any FCC self-test faults and FCC interface faults from the associated system interfaces.
(3)
02 TMC
(a) Displays any TMC self-test faults and TMC interface faults from associated system interfaces.
