Hydraulic Subsystems Malfunctions
MOTIVATION
Although these malfunctions are presented separately, one malfunction might
well cause another. Likewise, multiple, unrelated malfunctions could occur
simultaneously. In the simulator, they certainly will. Later in the curriculum,
you’ll learn the precise emergency procedures to take in response to each of
the malfunctions described in this lesson.
OVERVIEW
This lesson will help you to recognize and analyze hydraulic subsystem
malfunctions in a logical cause-and-effect sequence, beginning with a visual
review of how the subsystem should function and addressing the malfunctions
in three phases:
*
Indications
*
Verifications
*
Effects on flight safety
This lesson presents the following hydraulic subsystem malfunctions:
*
Unsafe gear on retraction
*
Gear door malfunctions
*
Wheel brake failure
*
Wheel brake/emergency flap accumulator failure
*
Anti-skid failure
*
Parking brake failure
*
Nose wheel steering (NWS) failure
*
Launch bar failure
*
Tail hook malfunctions in the landing phase
REFRESHER
