              86.  Landing in Manual

              (a)  Until pilots have considerable experience of flying in Manual control,
                   practice landings should be made only in ideal conditions, i.e. a
                   steady wind down the runway.  Because any asymmetric lowering of
                   the undercarriage is liable to cause lateral control difficulties, the
                   undercarriage must be lowered at a safe height.  A wider than normal
                   circuit should be made, followed by a long straight powered approach.
                   When the airspeed is below 150 knots with undercarriage and full
                   flap down, appreciable aileron buffet can be felt on the control
                   column.  If an overshoot has to be made, the undercarriage should
                   not be raised until a safe height is reached.  Flaps must only be selected
                   up to a mid-position because of a nose-up change of trim, full retrac-
                   tion being deferred to a safe height.
                     
              (b)  With external stores (See also para. 85 (b))
                   If the drop tanks are full or partly full they must be jettisoned before
                   landing.  Landing with any asymmetric loading other than one empty
                   inboard drop tank must not be attempted.  Trials have shown that
                   with a nominal 1,000 lb. weight on an inboard pylon the wings cannot
                   be held laterally level at speeds below 180 knots.  In turbulent condi-
                   tions asymmetrically-loaded RP's must be released if practicable; if
                   this is not possible great care must be taken when landing and not
                   more than 38° flap must be selected.
                    
              87.  Reselecting power
                     
                   Before reselecting aileron and/or elevator Power, the aircraft must
                   be trimmed, laterally and longitudinally, in straight and level flight
                   at the same airspeed and approximate altitude as when Manual was
                   selected.  Immediate reengagement is more likely on the elevator than
                   on the ailerons;it is therefore preferable to reselect elevator before
                   ailerons.  After reselection check that the appropriate magnetic
                   indicators are black.
                   
              88.  Clearing false anchorages (ailerons)
              
              (a)  If power is reselected below 10,000 ft. and a false anchorage occurs,
                   immediately switch Power OFF and either
                   
                   (i)   Return to base and land in Manual, or
                   
                   (ii)  Climb above 10,000 ft. before making any further attempts to
                         re-engage Power.
                         
              (b)  If Power is reselected above 10,000 ft. and a false anchorage occurs,
                   it may be cleared as follows:-
                   
                   (i)  One-way restriction
                   
                        The control column should be moved rapidly over its full move-
                        ment in the direction of unrestricted travel.  If the airspeed is
                        below 250 knots, this can be done without producing excessive
                        aircraft roll.
