Detail Steps/Work Items Key Items/References
(1) Connect the test equipment. Refer to the equipment manufacturers' manuals.
(2) Set the airplane altimeter to 1013.25 hPa (29.92 inHg).
(3) Monitor the altitude code. Decrease the pressure until the output code just changes to 20,000 ft.
(4) Make sure that the altimeter reading is within ± 125 ft of the encoder reading. If not, press the increase button (behind slot A) or decrease button (behind slot B) until the encoder reading is within 30 ft of the altimeter reading. Lightly tap the panel next to the altimeter to prevent errors due to friction.
(5) Increase the pressure until the output code just changes to 0 ft.
(6) Make sure that the altimeter reading is within ± 125 ft of the encoder reading. If not, press the increase button (behind slot A) or decrease button (behind slot B) until the encoder reading is within 30 ft of the altimeter reading. Lightly tap the panel next to the altimeter to prevent errors due to friction.
(7) Do steps 2 to 5 again until both 20,000 ft and 0 ft values are within the ± 125 ft tolerance.
(8) Operate the system through the range -1000 ft to 20,000 ft. Make sure that the altimeter and the encoder are within the ± 125 ft tolerance. Lightly tap the panel next to the altimeter to prevent errors due to friction.
(9) Disconnect the test equipment and remove it from the airplane.
