PART IV - EMERGENCY HANDLING
A.L.2 (h) If at altitude, delay opening the parachute for as long as
Para. 77 possible
and 78(i) (iii) For baling out below 2,000 ft., if the proper position on the seat
Page 59 can be maintained, the safety harness should be undone before
ejection.
78. Electrical system failures
(i) If for any reason it becomes necessary to turn off both battery
and generator the trimming controls will not work, the flaps will
not lower and most of the instruments will become unservice-
able. The fuel booster pumps will be inoperative which may
entail a reduction in r.p.m. and altitude to maintain satisfactory
engine running. Also some fuel (up to 170 lb.) may be trapped
in the aft fuselage tank and be unusable since the transfer pump
| is also inoperative. If complete electrical failure occurs the
| power controls alternate system will not operate either.
(ii) Generator failure
If the generator failure warning light comes on, switch
off all non-essential services immediately to reduce the
battery load. Hold the generator switch momentarily
at RESET and then turn the switch ON. If the generator
does not restart, the light will remain on, the switch
should be returned to OFF and a landing made as soon
as possible. When operating on the battery alone, power
is available for a period varying between 7 and 28
minutes depending on the services being operated and
the state of the battery.
(iii)Inverter failure
(a) If the single-phase inverter fails, the amber light (15)
comes on and the A.4 sight, the IFF, radar, the
cockpit temperature control system and the flow-
meter and totalizer will cease to function.
(b) If the main three-phase inverter fails, indicated by
the amber light (11) coming on, and the circuit
breakers are not tripped, the stand-by inverter
should be engaged by moving the instrument power
switch (113) to ALTERNATE, and the lights should
go out. If the stand-by inverter fails, the red light
(13) will come on and the A.C. operated flight
instruments will be unserviceable.
79. Power controls emergency operation
(i) If the normal power controls hydraulic system fails the
alternate system will automatically take over and the
alternate system indicator light will glow.
(ii) If the alternate system fails to take over automatically,
switch the flight controls switch to ALTERNATE ON.
(iii)If this fails to engage the alternate system, pull the
manual override handle.
80. Trimming controls emergency operation
If either of the normal aileron or tailplane trim controls
