If power must be re-established to navigation equipment to continue flight: If the faulty compo-
nent can be determined, pull the associated circuit breaker if not tripped already. Do not close the
open breaker to re--establish power to the failed circuit.
If the faulty component cannot be determined, pull all essential circuit breakers, switch the Mas-
ter switch ON and Alternator switch ON; then close circuit breakers one at a time. Permit a short
time to elapse before closing the next circuit breaker.
EMERGENCY DESCENT PROCEDURE
In the event an emergency descent from high altitude is required, rates of descent of at least
3,000 feet per minute can be obtained in two different configurations:
1.
With landing gear and flaps retracted, an airspeed of 194 KIAS will be required for maximum
rate of descent.
2.
With the landing gear extended and flaps retracted an airspeed of 164 KIAS will also give
approximately the same rate of descent. At 164 KIAS and the gear extended, the angle of
descent will be greater, thus resulting in less horizontal distance traveled than a descent at
194 KIAS. Additionally, descent at 164 KIAS will provide a smoother ride and less pilot work
load.
THEREFORE; The following procedure is recommended for an emergency descent:
