(21) GUN 001-050, 052-999; Ground Test - LRU - 04 MCP (Steps 13-20) (Fig. 19)
(a) MCP Test Steps 13-20 Description
1) Step 13 - Action message 04 PUSH DISENG BAR DN instructs the operator to position the disengage bar down. The CPU verifies that the AIM label 356, word 6, bit 14 is set to logic one. The CPU advances to the next test step.
2) Step 14 - Action message 04 PUSH DISENG BAR UP instructs the operator to position the disengage bar up. The CPU verifies that AIM label 356, word 6, bit 14 is set to logic zero. The CPU advances to the next test step.
3) Step 15 - Action message 04 SET BANK LIM TO 25 instructs the operator to position the bank limit selector switch to
25. The CPU verifies that AIM label 356, word 6, bit 18 is set to logic one. The test advances to the next test step.
4) Step 16 - Action message 04 SET BANK LIM TO 20 instructs the operator to position the bank limit selector switch to
20. The CPU verifies that AIM label 356, word 6, bit 19 is set to logic one. The test advances to the next test step.
5) Step 17 - Action message 04 SET BANK LIM TO 15 instructs the operator to position the bank limit selector switch to
15. The CPU verifies that AIM label 356, word 6, bit 20 is set to logic one. The test advances to the next step.
6) Step 18 - Action message 04 SET BANK LIM TO 10 instructs the operator to set the bank limit selector switch to 10. The CPU verifies that AIM label 356, word 6, bit 21 is set to logic one. The test advances to the next step.
7) Step 19 - Action message 04 SET BANK LIM TO 5 instructs the operator to set the bank limit selector switch to 5. The CPU verifies that AIM label 356, word 6, bit 22 is set to logic one. The test advances to the next test step.
8) Step 20 - Action message 04 SET BANK LIM TO AUTO instructs the operator to position the bank limit selector switch to AUTO. The CPU verifies that ARINC label 356, word 6, bit 23 is set to logic one. The test advances to the next test step.
