The operation of the solenoid valves can be summarized as follows:
Deviation From
Limit Exceedance Programmed Limit Solenoid Valves Actuated
Altitude
± 1000 ft, 350 m SV1A, SV1B
Airspeed ± 50 kts, 100 km/hr SV1A, SV1B, SV3A
VSI ± 500 ft/min, 150 m/min SV1A, SV1B, SV2A, SV2B
Mach ± 0.2 mach SV1A, SV1B, SV3A
Note: It is imperative that the operator monitors the displayed parameters closely to avoid
excessive differential pressures between the test set and the aircraft systems once the
solenoid isolation valves are actuated. Refer to Operations paragraph
D.
