PART 1-DESCRIPTIVE
(c) (i) There is a hood locking indicator (73) on the star-
board wall of the front cockpit. When the starboard
catches are correctly engaged, the two white pointers
on the indicator are in line.
(ii) Fighter Command Mod. 40 introduces a spring-
loaded pushbutton on the port wall of the from cock-
pit; it can only be depressed when the locking handle
is in the correct locked position.
(iii) Mod. 1787 introduces a hood warning light in each
cockpit. That in the front cockpit is above the wind-
screen, to port of centre and that (106) in the rear
cockpit is at the forward end of the cockpit wall. The
light comes on when the hood is not locked shut.
(d) Hood jettisoning
There is a hood jettisoning handle (44) (108) on the starboard
side of each instrument panel. When either handle is pulled
out, both port and starboard hood catches are released,
allowing the hood to swing up and back about the rear
hooks; the hood disengages from the hooks when it
reaches an angle of about 40°.
28. Seats and harness
Both seats can be adjusted for height by levers on the star-
board side of the seats. The lean-forward releases (74)
(121) for the Z-type harness are on the starboard wall of
each cockpit. A dinghy guard is fitted to the front of each
seat.
29. Cockpit heating
(a) The cockpits are supplied with warm air from the engines
and the heating in both cockpits is controlled by a lever
(71) on the starboard wall of the front cockpit. The for-
ward position of the lever is the OFF position and the lever
is moved progressively backwards to ON to increase the
heat in both cockpits. This control should be OFF during
take-off, to prevent fumes entering the cockpit.
(b) A ventilation control (14) on the port wall of the front
cockpit operates a cold-air intake valve and a stale-air
outlet valve. The control is pulled back progressively to
open both valves. 24
