PART 1-DESCRIPTIVE

          (17) and GUNS/RP selector switches (59) (60) are on the
          port side of the instrument panel and the electrically-
          operated ranging control is incorporated in the throttle
          twist-grip. Circuit breakers (41) are provided on the
          instrument panel. A changeover switch (42) for the
          ranging control is on the starboard side of the instrument
          panel.

      46. G.G.S. emergency lowering

          Should either gunsight fail to lower by the normal
          method, emergency lowering may be effected by striking
          the knob (21) (36) adjacent to the gunsight, a hard blow.

      47. G.45 camera

      (a) The cine-camera automatically operates during both R.P.
          and gun firing when the camera master switch (at 40) is
          ON. An aperture switch (at 40) is positioned on the
          right-hand side of the instrument panel.

      (b) The test switch (43) is below the G.G.S. circuit breakers.

      48. Gun firing

      (a) Gun firing controls are located on each control column
          and consist of a firing switch and a safety switch. Both
          safety switches must be at FIRE before either firing switch
          will fire the guns. When the catch is at SAFE and the
          camera master switch on the upper panel is ON, the
          cine-camera can be operated by pressing the port button
          on either control column.

      (b) A micro switch in the nose-wheel well isolates the firing
          circuits when the nose-wheel is down and locked. For
          added safety, when the guns are loaded, the electrical
          leads to the gun firing units should be left unconnected
          until just before flight.

      49. R.P. firing and bomb release

      (a) A BOMBS/R.P. master selector switch (45) is on the
          starboard panel together with a PAIRS-SALVO switch.
          A firing push switch is on each control column.
