-set a static pressure of 977.1 hPa (1000 ft or 305 m).
-Set a static pressure of 908.1 hPa (3000 ft or 915 m).
Make sure that the standby altimeterindicates 1000 ft (+ or - 20 ft) andthe metric altimeter indicates 305 m (+ or - 15 m).
-Make sure that the standby altimeterindicates 3000 ft (+ or - 30 ft) and the metric altimeter indicates 915 m (+ or - 20 m).

________ Subtask 34-21-00-860-054
 A. Put the aircraft back to its initial configuration.
 (1)
 Disconnect the ground pressure generator.

 (2)
 Remove the adaptor from the standby static probe.

 (3)
 Remove the cover from the opposite standby static probe.

 (4)
 Install the slip on covers on the static probes.

 (5)
 Close the LGCIU circuit breakers and put the aircraft back to its inertial cofiguration (Ref. TASK 32-00-00-860-002).

 (6)
 De-energize the aircraft electrical circuits
 (Ref. TASK 24-41-00-862-002).
