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.
