                           PART 1-DESCRIPTIVE

    (b)  Emergency operation

         If hydraulic pressure falls, the airbrakes may be operated
         by the handpump, after making the normal selection.


    24.  Wheelbrakes
    
         The pneumatically-operated wheelbrakes are controlled by
         a lever on each control column.  Differential braking is
         obtained by operating the rudder pedals with either of the
         levers pressed.  The pressure at each wheel (120 lb./sq.in.
         max) may be read on the triple pressure gauge (8) on the
         port wall of the front cockpit.  A parking catch is incor-
         porated on the front control column and, pre-Mod. 813, on
         the control column in the rear cockpit.


    25.  Flight instruments
    
    (a)  A.S.I. and associated instruments

           (i)   A combined pitot-static pressure head on the port
                 wing supplies pressure for the operation of the
                 A.S.I.s, V.S.I.s and altimeters.
                 
           (ii)  The pressure head can be electrically heated, the sup-
                 ply being controlled by a switch (61) on the starboard
                 switch panel in the front cockpit.

    (b)  Compass and direction indicators                 

           (i)   Remote indicating compasses

                 Pre-Mod. 1177, there is a remotely-indicating compass
                 in the front cockpit, the electrical supply being con-
                 trolled by a switch on the starboard switch panel in
                 the front cockpit.

           (ii)  Mk. 4F compass

                 Mod. 1177 introduces a MK. 4F compass (39) in the
                 front cockpit, together with an A.C. voltmeter (53)
                 below the main instrument panel and a corrector
                 control box (126) in the rear cockpit.  The electrical
                 supply is controlled by a master switch (59) and D.C.
                 (65) and A.C. (64) NORMAL-EMERGENCY
                 switches (see para. 16(c)).  When I.L.S. is installed, the
                 Mk. 4F compass is replaced by a Mk. 4FT.
