PART IV-EMERGENCY HANDLING
(b) Actions in the event1 of engine failure - hydraulics
serviceable:
(i) Engine windmilling: Sufficient hydraulic power
should be available for power controls provided that
unnecessary operation of airbrakes is avoided.
Reference should be made to the hydraulic accumu-
lator gauges to check the available hydraulic pressure
remaining. Select elevator and aileron Power off
before selecting normal or emergency undercarriage
and flap down, if a wheels-down landing is being
attempted.
(ii) Engine seized: Do not use the airbrakes to reduce
speed. As soon as the aileron and elevator accumu-
lators are exhausted the respective controls will
revert to Manual, but in any case select elevator and
aileron Power OFF before landing.

A.L.2 86. Undercarriage and flaps emergency operation
Page 86
(a) (i) (a) (i) Although the emergency lowering systems will operate
Page 76 irrespective of the position of their normal selectors, the
respective normal selector should whenever possible be
set to the Down position before operating the emergency
control. This will obviate any possibility of the service
subsequently retracting should a fault occur in the emer-
gency system.
(ii) Full flap only will be obtained regardless of the position of
the limit setting switch.
(b) If either service fails to operate due to an electrical failure the
appropriate emergency control should be operated. All other
hydraulic services will then continue to operate normally.
------------------------------------------------------------------
(c) [Line missing]
warning, power controls should be selected to Manual.
The undercarriage should be lowered by pressing the
emergency button on the rear face of the port console,
after which the flaps may be lowered by use of the
adjacent emergency flap lowering button.
(d) If the undercarriage lowers when selected normally but
three green lights are not obtained because of a micro-
switch failure or failure of an undercarriage lock to
engage, operation of the emergency system will lower
the hydraulic pressure available by approximately 1,00076
