PART IV - EMERGENCY HANDLING
(ii) At normal gliding speeds, with a windmilling engine, the
generator r.p.m. is too low to provide power and the
battery is the only source of power. Switch OFF the
engine master switch (L.P. cock), IFF, radar, radio,
armament equipment, pressure head heater and unneces-
sary lighting to conserve the battery.
(iii) If engine damage prevents windmilling, causing failure
of the normal flying control system, the alternate control
system will come into operation. This will impose the
maximum drain on the battery power, resulting in the
minimum usable battery life.
(iv) If committed to a forced landing the recommended
procedure is as follows:-
A.L.1 (a) Jettison all external stores or drop tanks,
open or jettison canopy.
(b) The best range gliding speed for the clean aircraft
is 185 knots.
(c) On reaching the landing area, decide whether to
lower the undercarriage and, if suitable, lower it.
(d) Position the aircraft, using the flaps as required,
maintaining a speed of at least 160 knots.
(e) At the same speed turn onto the final approach
aiming to have the flaps fully down on the final
approach.
(f) Prior to crossing the boundary of the landing area,
open the air brakes and touchdown at any speed
below 160 knots.
(g) If undershooting, maintain 160 knots for as long as
possible, then reduce the speed to 120 knots to gain
distance. Delay the opening of the air brakes.
(h) When landing with the undercarriage up. the aircraft
should be flown onto the ground at about 150 knots.
At lower speeds the marked nose-up attitude may
cause the aircraft to cartwheel immediately after the
initial touchdown.
87. Ditching
(i) Whenever possible the aircraft should be abandoned as
the ditching characteristics are not good.
(ii) If ditching is inevitable the following is the recommended
procedure:-
(a) Jettison all external stores, and open the hood at
less than 215 knots.
(b) Keep the wheels up and air brakes in and close the
throttle to OFF.
