Hydraulics Flashcards
The following lights illuminate:
MASTER CAUTION
FLT CONTROL A LOW PRESSURE
HYD PUMPS ENG 1 LOW PRESSURE
HYD PUMPS ELEC 2 LOW PRESSURE
Q.4.1 What is your assessment of the problem?
Loss of system A hydraulics
FRM 13.1.3, 15.2.3.1
The following lights illuminate:
MASTER CAUTION
FLT CONTROL A LOW PRESSURE
HYD PUMPS ENG 1 LOW PRESSURE
HYD PUMPS ELEC 2 LOW PRESSURE
Q.4.2 Other than the above lights, what other indications can help you confirm loss of system A hydraulics.?
HYDRAULIC indications on MFD, A autopilot disconnected if in use
FRM 13.2.2, QRH 13.4
Q.4.3 What major systems are affected with the loss of system A hydraulics?
- Autopilot A
- Normal landing gear extension and retraction
- Ground spoilers
- Engine 1 thrust reverser normal hydraulic pressure
- Normal nose wheel steering
FRM 13.2.2, QRH 13.4
The following lights illuminate:
MASTER CAUTION
FLT CONTROL A LOW PRESSURE
HYD PUMPS ENG 1 LOW PRESSURE
HYD PUMPS ELEC 2 LOW PRESSURE
Q.4.4 What non-normal checklist is applicable?
LOSS OF SYSTEM A
QRH 13.4
Q.4.5 What does PWB take into account when computing performance data with a loss of system A hydraulic?
Increased landing distance due to:
1. Inoperative ground spoilers and
2. Slower-than-normal thrust reverser deployment on engine 1
QRH 13.4
Q.4.6 With the loss of system A hydraulics, can you continue to your destination?
Yes, unless you lose another hydraulic system
AOM 5.1.1
Q.4.7 With the loss of system A hydraulics, shat should you consider when in the terminal area?
When the gear has been lowered manually, it cannot be retracted. The drag penalty with gear extended may make it impossible to reach an alternate field.
QRH 13.4
The following lights illuminate:
MASTER CAUTION
FLT CONTROL B LOW PRESSURE
HYD PUMPS ENG 2 LOW PRESSURE
HYD PUMPS ELEC 1 LOW PRESSURE
Q.4.8 What is your assessment of the problem?
Loss of system B hydraulics
FRM 13.1.3, 15.2.3.1
Q.4.9 What major systems are affected with the loss of system B hydraulics?
- B autopilot
- Yaw damper
- Trailing edge flaps and leading edge devices normal hydraulic pressure
- Autobrake
- Normal brakes
- Engine 2 thrust reverser normal hydraulic pressure
- 2 spoilers each wing.
FRM 13.2.2, QRH 13.6
Q.4.10 With a loss of system B hydraulics, Why do you plan a Flaps 15 landing?
To improve go-around capabilities.
AOM 5.11.1
Q.4.11 After a loss of system B hydraulics, what would you do if you also had STANDBY HYD LOW QUANTITY?
Plan to land at the nearest suitable airport.
AOM 5.1.1
Q.4.12 With a loss of system B hydraulics, what should you consider prior to extending the flaps?
Leading edge devices cannot be retracted after extension with alternate flap extension system. The drag penalty with leading edge devices extended may make it impossible to reach an alternate field.
QRH 13.6
Q.4.13 Before pushback, which hydraulic system must be depressurized (both pumps OFF and LOW PRESSURE lights illuminated)?
System A
AOM 3.13
Q.4.14 The aircraft must not be towed forward unless both engines are shut down and which hydraulic system is depressurized?
System A
AOM 3.13
Q.4.15 How can the standby hydraulic pump be activated?
Manually: By moving either FLT CONTROL switch to STBY RUD or ALTERNATE FLAPS master switch to ARM.
Automatically: Inflight or on the ground with a loss of system A or B, under specific conditions, or Force Fight Monitor (FFM) activation.
FRM 13.2.3.1, 13.2.3.2
