HYD G RSVR LO AIR PR

Question 1

Triggering conditions:

Answer 1

When the hydraulic reservoir air pressure is equal to or less than 22psi.
The alert resets when the reservoir air pressure is equal to or greater than 25psi

Question 2

If pressure fluctuates:

Answer 2

PTU OFF

GREEN ENGINE 1 PUMP OFF

Question 3

ASSOCIATED PROCEDURES

G SYS LO PR

Answer 3

Fuel consumpt incr
-Triggered by a change in the nominal aerodynamic characteristics of the aircraft.

FMS predictions unreliable
-Disregard FMS fuel predictions and refer to QRH/PER-B for fuel penalty tables.

Question 4

STS

APPROACH PROCEDURES.

The probability of cavitation increases with altitude, therefore descending to a lower altitude may:

Answer 4

Reset the system.

Question 5

APPROACH PROCEDURES:

Answer 5

G Eng 1 Pump ON

     * *If HYD not recovered 
         - L/G Grvty Extn
         - Ldg dist proc apply

Fuel consumpt incr
FMS predictions unreliable
Altn Y brake with A/skid
-Braking uses this mode when green system
pressure is insufficient and:
-Yellow hydraulic pressure is available
-A/SKID, N/W STRG switch is on
-The parking brake is not on.

Slats/Flaps Slow
CAT 3 single only

Question 6

STS

INOP SYSTEMS:

Answer 6

Green HYD
SPLR 1 and 5
CAT 3 Dual
Autobrake 
Normal brake
L/G retract
Reverser 1 (hydraulically actuated via G SYS)
Yaw damper 1 (FAC 1 uses G SYS pressure)
