PART 1 - DESCRIPTIVE
(d) (i) A "flood flow" valve is incorporated in the system
which may be controlled in AUTO or MANUAL
according to the setting of the FLOOD AIR FLOW
control switch (11).
(ii) When the switch is set to MANUAL, "flood flow"
is brought into operation and is used primarily for
clearing any transparency misting.
(iii)When the switch is at AUTO, should loss of cockpit
pressure cause the cockpit altitude to exceed 38,000
ft., an altitude switch operates to supply "flood"
air to the cockpit.
(e) A switch (10) for ground testing the visual warning and
flood air supply is aft of the normal controls. It must not
be used in flight.
39. Anti-G suit system
(a) The purpose of the system is to provide air at low
pressure for the pilot's anti-G suit, the connection for
which is on the port side of the ejection seat.
(b) Air under pressure is stored in two air bottles, the
contents of which are indicated by a pressure gauge (81)
on the starboard wall. When the cock (79) below the
gauge is ON and G in excess of approximately 1½ is
applied, a spring-loaded valve operates and allows air to
pass to and inflate the anti-G suit. The amount of
inflation depends on the amount of G applied.
(c) The system may be tested, with the cock ON, by pressing
the ANTIG-TEST button (80), adjacent to the on/off
cock, as gently as possible to avoid severe discomfort due
to too rapid inflation.
