Functional Test of the ADM Accuracy
WARNING:
MAKE SURE THAT ALL THE CIRCUITS IN MAINTENANCE ARE ISOLATED BEFORE YOU SUPPLY ELECTRICAL POWER TO THE AIRCRAFT. UNWANTED ELECTRICAL POWER CAN BE DANGEROUS.
WARNING:
MAKE SURE THAT THE SAFETY DEVICES AND THE WARNING NOTICES ARE IN POSITION BEFORE YOU START A TASK ON OR NEAR:
- THE FLIGHT CONTROLS
- THE FLIGHT CONTROL SURFACES
- THE LANDING GEAR AND RELATED DOORS
- COMPONENTS THAT MOVE.
WARNING:
MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
CAUTION:
TO PREVENT DAMAGE TO INSTRUMENTS, OBEY THESE PRECAUTIONS WHEN YOU DO THE TEST:
- THE PRESSURES SET MUST NOT BE MORE THAN 1050 hPa (31 in Hg) OR LESS THAN 115 hPa (3.39 in Hg)
- CHANGES IN STATIC AND TOTAL PRESSURES MUST NOT BE MORE THAN 6000 FEET/MINUTE
- DO NOT SUDDENLY OPEN LINES TO AMBIENT AIR WHILE THE PRESSURE GENERATOR IS CONNECTED.
CAUTION:
THE TOTAL PRESSURE IN THE PITOT SYSTEM MUST NEVER BE LESS THAN THE STATIC PRESSURE. THE DIFFERENCE BETWEEN THE PITOT AND THE STATIC PRESSURE CIRCUITS MUST NEVER BE MORE THAN 368 hPa (10.86 in Hg).
1. Reason for the JobRefer to the MPD TASK: 341300-13

G. Installation of the Ground Pressure Generator
(1) When you operate the ground pressure generator, use the parameters that follow:
(3) (a) The static probes with the ADAPTER STATIC PROBE (4):
1 For the CAPT circuit (Air Data/Inertial Reference Unit 1 (ADIRU 1)) and the F/O circuit (ADIRU 2):
1 For the standby circuit (ADIRU 3):
1 For the CAPT circuit (ADIRU 1):
(b) Make sure that you can see the adhesive tape from the ground.
(5) Seal the opposite static probe of the standby ADM with the ADAPTER STATIC PROBE.
(6) Set the Angle Of Attack (AOA) sensors to the high stop position
(a) Slowly turn the vanes of the three AOA sensors to the high stop position.
(b) Keep the vanes in position with the adhesive tape.
(7) Start the ground pressure generator.
4. Procedure(1) When you operate the ground pressure generator, use the parameters that follow:
- The altitude between -1000 ft. (-304.79 m) and 50000 ft. (15239.72 m) (accuracy +/- 0.1 hPa (0.00145 psi)) or the values in feet that follow, in relation to the altitude level:
Sea level: +/- 3 ft. (0.91 m)
5000 ft. (1523.97 m): +/- 4 ft. (1.22 m)
30000 ft. (9143.83 m): +/- 8 ft. (2.44 m)
50000 ft. (15239.72 m): +/- 18 ft. (5.49 m). - The speed between 0 and 500 kts.

CAUTION:
WHEN YOU SEAL THE DRAIN HOLE IN THE PITOT PROBE, DO NOT SEAL THE HOLE DIRECTLY WITH THE COLORED ADHESIVE TAPE. ALWAYS PUT A PIECE OF PLASTIC ON THE HOLE FIRST AND USE THE COLORED ADHESIVE TAPE TO ATTACH THE PLASTIC.
IF YOU SEAL THE DRAIN HOLE DIRECTLY WITH THE ADHESIVE TAPE, THERE IS A RISK THAT SOME OF THE ADHESIVE WILL STAY ON THE HOLE AND COLLECT PARTICLES. THIS CAN SUBSEQUENTLY CAUSE BLOCKAGE OF THE HOLE AND THUS INCORRECT OPERATION OF THE PROBE.
(a) Seal the drain holes of the pitot probes with the SHEET - PLASTIC and the color TAPE - ADHESIVE.(b) Make sure that you can see the adhesive tape from the ground.
(5) Seal the opposite static probe of the standby ADM with the ADAPTER STATIC PROBE.
(6) Set the Angle Of Attack (AOA) sensors to the high stop position
(a) Slowly turn the vanes of the three AOA sensors to the high stop position.
(b) Keep the vanes in position with the adhesive tape.
(7) Start the ground pressure generator.
