GENERAL FLYING

  10.      Stability and control

      (i)  This aeroplane is stable.  With metal covered ailerons
           the lateral control is much lighter than with the
           earlier fabric covered ailerons and pilots accustomed
           to the latter must be careful not to overstress the
           wings.  Similar care is necessary in the use of the
           elevators which are light and sensitive,

     (ii)  For normal cruising flight the radiator shutter should
           be in the minimum drag position.

    (iii)  Change of trim

           Undercarriage down		-	nose down
           Flaps down			-	nose down

     (iv)  Maximum range is obtained with WEAK mixture,
           1,700 r.p.m. and at 160 m.p.h. A.S.I.R.

      (v)  Maximum endurance is obtained with WEAK mixture,
           1,700 r.p.m. and at the lowest speed at which the
           machine can be comfortably flown.

      (vi) For combat manoeuvres, climbing r.p.m. should be used.

     (vii) For stretching a glide in the event of a forced
           landing, the airscrew speed control should be pulled
           right back and the radiator flap put at the minimum
           drag position.
           
                                 STALLING
   
  11.  (i) At the stall one wing will usually drop with flaps
           either up or down and the machine may spin if the
           control column is held back.
             
      (ii) This aeroplane has sensitive elevators and, if the
           control column is brought back too rapidly in a
           manoeuvre such as a loop or steep turn, stalling
           incidence may be reached and a high-speed stall
           induced.  When this occurs there is a violent shudder
           and clattering noise throughout the aeroplane, which
           tends to flick over laterally and, unless the control
           column is put forward instantly, a rapid roll and
           spin will result.
           
     (iii) Approximate stalling speeds when loaded to about
           6,250 lb. are:-
           
           Flaps and undercarriage UP	73 m.p.h. A.S.I.R.
             "    "        "       DOWN	64   "       "
