Read the following technical passage:

During pre-flight pressure testing of an aircraft's pitot-static system, technicians connect a calibrated field test set to the fuselage pitot probe adapter. To prevent rupture of the internal airspeed indicator diaphragms, the pitot line pressure must not exceed 25 inches of water before the static equalization valve is opened. If the test set displays an unexpected differential pressure spike, the technician must immediately vent the pneumatic manifold using the manual dump valve rather than cycling the electrical pump switch. This ensures that moisture and pressurized air escape without straining the sensitive aneroid wafers.

According to the passage, what action must a technician take if an unexpected differential pressure spike occurs?

  1. A
    Cycle the electrical pump switch to reset system flow
  2. B
    Disconnect the field test set from the fuselage probe adapter
  3. Vent the pneumatic manifold using the manual dump valveCevap
  4. D
    Adjust the pitot line pressure to exceed 25 inches of water

Cevap

Vent the pneumatic manifold using the manual dump valve
The author explicitly states that if the test set displays an unexpected differential pressure spike, the technician must immediately vent the pneumatic manifold using the manual dump valve.

Adım Adım Çözüm

1
