                   essential and a descent in Manual is being made, control
                   is more comfortable at 175 knots.

A.L.2    (c)   Check and/or set the following:-

                  H.P. and L.P. cocks               OFF 
                  Booster-pumps                     OFF
                  Tailplane incidence               ½° nose-up
                                                               Tailplane switch OFF
                  All non-essential electrics     OFF
                  Aileron trim                           Safety lock off
                                                               Indicator zero
                  Elevator and aileron             Leave on temprorarily, but
                     power                                   select OFF
                                                              (1) Before electric power fails
                                                              (2) If a false anchorage occurs
----------------------------------------------------------------------------------------
     (d)  (i)  Engine failure may lead to either or both electrical
                and hydraulic failure.  Experience shows that at
                200 knots windmilling r.p.m. will create sufficient
                hydraulic pressure for limited use of the power
                controls, but large or frequent use of the controls
                or selection of any of the services may cause Manual
                reversion.  If pressure then rebuilds, false anchorages
                may occur
                
           (ii) Selecting Power off can only be accomplished
                whilst electrical power is available.  To avoid the
                danger of obtaining a false anchorage with no
                electrical power available and to prevent inadvertent
                Manual reversion at an inconvenient stage of the
                approach, select Power off before electrical failure
                occurs.  When gliding at 210 knots, windmilling
                r.p.m. at high altitude will be sufficient to keep the
                generators charging, but r.p.m. will decrease gradu-
                ally as height is lost.  Frequent checks on the gener-
                ator warning lights should be made, and after they
                come on, the batteries should not be relied on for
                more than 5 minutes.
