RAT GEN FEED
Emergency AC power is supplied by the ram air turbine (RAT) in flight, rated at 115volts, 9 kVA,
3−phase. With a dual−engine failure, the RAT will deploy automatically, regardless of slat/flap handle
position. The RAT can also be manually deployed by pulling RAT manual deploy handle, located on
the center pedestal.
With engines running, the RAT will deploy with a 14−second time delay following the loss of all AC
power, if the slat/flap handle is at the in/zero position. And if the flaps/slats are deployed, with a loss
of all AC power, the RAT will deploy immediately and will supply power to AC ESS within 6 seconds
of deployment.
The RAT will supply power to AC ESS within 6 seconds of deployment. This delay is implemented to
allow the pilot to regain GEN 1−2−3 or 4 or APU GEN power.
In the event that an operating generator is restored, select the RAT GEN switch to OFF with the RAT
manual deploy handle in the stowed position. The RAT GEN will remain in a standby mode.
