Engine and Hydraulic Emergency Procedures
b.
At 1,660 + 110 psi
(1) MSTR ALERT light flashes and caution
tone sounds
(2) HYD 2 PRESS caution light illuminates
c.
Ram air turbine (RAT) extends at 1,500 psi, and
HYD 2 pressure cycles between 2,500 and
3,000 psi
NOTE: If the failure of HYD 2 results from an
engine-driven pump (EDP) failure (with no
leak), then pressure is supplied by the RAT
through the Emergency Hydraulic system. If
the failure includes a complete or continuing
loss of fluid, then cycling pressure (indicative of
RAT operation) may be only temporary, if it
occurs at all.
d.
RAT continues to operate normally--i.e., gauge
continues to fluctuate between approximately
2,500 and 3,000 psi

hydraulic pumps and the RAT, the latter being highly
unlikely. Proper handling of this emergency and thorough
knowledge of the system is essential to the safe outcome
of this emergency.
