PART I-DESCRIPTIVE

                 harness will remain locked until the lever (102) is moved
                 to the locked position and then back to unlocked.
                 by raising the left-hand grip (101) of the seat.

          33.    Anti-G suit provisions

                 An air pressure outlet connection (104) on the front of
                 the seat is provided for attaching an anti-G suit.  A valve
                 (99) on the left aft console has two settings HI and LO.
                 Accelerations above 1.75G (approx.) cause the valve to
                 open and inflate the suit.  For each additional force of
                 1G a corresponding 1 lb./sq. in. (LO setting) or 1½ lb./sq.
                 in. (HI setting) air pressure is exerted in the suit.  A
                 button (98) on top of the valve, when pressed, inflates
                 the suit momentarily and is used to lessen fatigue during
                 long flights

           34.   Cockpit lighting

                 Three rheostat switches, mounted on a panel on the cock-
                 pit starboard wall, control the cockpit lighting.  The
                 left-hand switch (89) controls the individual ring lights
                 fitted round each instrument, the centre switch (90) con-
                 trols the two auxiliary floodlights mounted on each side
                 of the cockpit, and the right-hand switch (91) controls
                 the lighting of the consoles and the central armament
                 panel.  This switch also acts as a master switch for the
                 light in the stand-by compass which can be switched on
                 and off by a switch (85) on the right forward console.
                 The auxiliary floodlights are operable at all times
                 irrespective of the position of the battery switch or
                 whether the engine is running or not.
                 
           35.   Exterior lighting

           (i)   Navigation lights and fuselage lights
                 The navigation lights on the wing tips and tail and the
                 two white fuselage lights, one at the back of the canopy
                 and the other below the fuselage are controlled by a
                 two-position dimmer switch (78) marked BRIGHT and
                 DIM, and a three-position selector switch (86) marked
                 OFF, STEADY and FLASH.  Both switches are on the
                 forward right console and when the selector switch is at
                 FLASH the wing tip lights go on and off and the tail
                 lights alternate from white to yellow but the fuselage
                 lights remain on.  With the switch at STEADY all the
                 lights remain on.
