PART IV - EMERGENCY HANDLING
but should a false anchorage occur and in any case
before landing, switch OFF elevator and aileron
Power.
AL1 Mods. 452 and 502 are not embodied and
(iv) If^a partial hydraulic failure occurs subsequent to
complete electric failure when the controls are still
in Power, the landing is likely to be extremely
hazardous, and it is recommended that the aircraft
be abandoned.
92. Engine failure and flame-out
(a) Engine seizure
Engine seizure will involve both hydraulic and electric
supply failure. If the engine has failed due to obvious
mechanical causes do not attempt to relight. Proceed as
follows:-
(i) Close the throttle. Turn off the H.P. and L.P. cocks
and switch off the booster-pumps.
(ii) Reduce speed and glide at 210 knots.
AL1 (iii) Switch off all unnecessary electrics and tailplane.
AL1 (iv) Set tailplane incidence to ½° nose-up. Release aileron trim
safety lock and check that trim indicator is at zero.
(v) The controls may be left in Power, but Manual
reversion must be expected.
(vi) Carry out forced landing procedure (see para.94) or
abandon.
(b) Flame-out
AL1 (i) If flame-out occurs, when the engine is at or above
cruising power it will be indicated by the r.p.m.
decreasing at approximately 1,000 r.p.m. per second
initially. A relight may be attempted immediately,
while the r.p.m. are decreasing, by holding the relight
switch at RELIGHT for two seconds and then
releasing it, leaving the throttle at its set position. A
successful relight will be indicated by the r.p.m.
stabilizing and then commencing to rise. The j.p.t.
gauge should be checked to ensure, by throttling
