G. Do the Test for the Air Mode
S 042-058
WARNING: DO THE PROCEDURE TO PREPARE THE SAFETY-SENSITIVE SYSTEMS FOR
_______ AIR MODE SIMULATION. IF YOU DO NOT DO THE PROCEDURE BEFORE YOU SIMULATE AIR MODE, INJURY TO PERSONS OR DAMAGE TO EQUIPMENT CAN OCCUR.
(1)
Do the task to Prepare the Safety-Sensitive Systems for Air Mode Simulation before you simulate the air mode.
S 862-059
(2)
Put the actuators and deactuators on the proximity sensors of the landing gear to simulate the air mode.
NOTE: See the task to Put the Air/Ground Relay System in the Air
____
Mode.
S 862-060
(3)
Supply electrical power (AMM 24-22-00/201).
S 762-047
(4)
Do a continuity check for the air/ground relay.
NOTE: Refer to Table 201 for the condition of the relay
____ (energized or de-energized). When you do the continuity check, make sure the electrical power is removed from the system connected to the relay.
S 712-048
(5)
On relay K142 or K202, do the MCDP test(s) 51 AIR/GND RLY to make sure the Autopilot/Flight Director and the Thrust Management System Interface operates (AMM 22-41-00/501).
H.
Put the Airplane Back to Its Usual Condition
(1)
Do the task to put the air/ground relay system in the ground mode.
