(b) System Tests Description 1) 30 CURRENT FAULT REPORT a) Displays all LRU and interface faults detected and stored in the FCCs and TMC while the MCDP operates in the ground test mode. Ground fault messages and diagnostic codes are the same as flight fault messages except the flight deck effect and intermittent bit status are not displayed. b) Provides interaction message to allow operator to skip Interface Fault messages. c) Provides interaction message to allow operator to select current Ground Fault display. 2) 40 AUTOLAND a) Displays the current ground faults and interface faults related to the autoland system. The autoland related interfaces are automatically monitored. It automatically performs LRU and support tests related to the autoland system that do not require interaction with the operator. b) Automatically performs LRU and support tests related to the autoland system that require no manual preconditioning except for applying electrical power. c) Automatically performs LRU and support tests related to the autoland system that require manual preconditions but no hydraulic power.
d) Performs manual interface checks related to the autoland system. e) Performs manual LRU and support tests related to the autoland system. f) Performs A/P servo and stab trim tests.
(c) Support Test Description 1) 51 AIR/GRD RLY a) Displays any FCC and TMC self-test faults and any interface faults related to air/ground relay. b) Interaction test of the landing gear system 1 air/ground relay and its interface to the FCCs and TMC.
c) Interaction test of the landing gear system 2 air/ground relay and its interface to the FCCs.
