Page 53 (f)  The supplementary spin recovery action is:- 
Para 70         (i)  Check that correct full anti-spin control has been applied, 
(cont.)                ensuring that the rudder is opposed to the indicated yaw.
A.L.3           (ii)  Apply full aileron in the direction of roll.

                The recovery with aileron in the direction of roll may be characterised
                by a sharp increase in the rate of rotation for about three turns
                before the spin suddenly changes to a spiral dive. The ailerons
                should be centralised immediately to avoid the development of a
                tight spiral with rapidly increasing airspeed.

         (g)  If an unintentional spin is entered recover in the incipient stage by
               centralising the controls and closing the throttle. If this is ineffective
               full spin recovery action must not be applied until the spin has
               developed in a downward direction.

               Note :-1.  If at 15,000 feet the aircraft is still spinning, jettison
                                  the canopy. This may aid recovery.
                          2.  If the spin is not under control at 10,000 feet the aircraft
                                must be abandoned. (Altimeter errors and fast rate of
                                descent leave no time for hesitation).
                          3.  The risk of disorientation may be reduced by looking at
                                the horizon through the canopy instead of the ground
                                through the windscreen.

   71.  Aerobatics

   (a)  Until experience is gained, the following speeds, in knots,
        are recommended:-

                 Roll	..	..	250-270
                 Loop	..	..	300-320
                 Roll off the top ..	340-360
                 Vertical roll		370 and above

   (b)  The centre tank collector box should ensure a supply of
        fuel for approximately 15 seconds flight under negative G
        conditions.

   (c)  Aerobatics are not permitted when carrying external
        stores.

   72.  High speed flying

   (a)  The high speed characteristics vary with altitude and
        individual aircraft, and machmeter errors may be con-
        siderable. The following compressibility effects are
        therefore quoted against approximate indicated mach
        numbers and reliance should be placed more on the
        behaviour of the aircraft than on machmeter readings.
        It is recommended that the performance of the aircraft
