PART 1V-EMERGENCY HANDLING
85. Action in the event of electrical failure
(a) Single generator failure
If either generator fails, the supply of the other is sufficient
to keep the battery charged.
(b) Double generator failure
In the unlikely event of both generators failing, all elec-
trical services will be supplied by the batteries. Switch off
all non-essential elctrical services, including the L.P.
pumps.
86. Hood jettisoning
(a) Reduce speed as much as possible. Then check:-
Seat Fully lowered
Gunsight Lowered
Harness Tight and locked
Helmet Strap fastened and tight
Before jettisoning the hood assume a position with head
well forward and down.
NOTE:-Unless the aircraft is being flown solo, reduce
speed to 150 knorts before jettisoning the hood.
At speeds above 200 knots it is very difficult, if
not impossibkle, to fly the aircraft from the rear
seat with the hood jettisoned.
(b) In the air, the hood is jettisoned by pulling the jettison
handle in either cockpit. To open the hood on the ground,
one of the normal release levers should be used, thereby
swinging the hood over the side, the jettison handle being
used on the ground only if the hood is jammed and the
normal method fails. If the normal method fails, the jetti-
son handle should be pulled to its fullest extent to release
the side toggles. The handle should then be released and
this will cause the rear hooks to disengage. The hood
should then be pushed off to the starboard side to clear the
assister arm. If the rear hooks do not disengage they can
be operated by pulling on one of the toggles on the star-
board side of each cockpit or by the external release on the
port side of the fuselage.
(c) In view of the above, the hood should, if time permits, be
jettisoned in the air before a crash landing or ditching. 61
