PART 1 - DESCRIPTIVE
40. Ejection seat Mk. 2H or Mk. 3H
WARNING.-1. The pilot must ensure that each safety
pin is removed and stowed before flight
and must lock each handle against the
possibility of accidental withdrawal on the
ground before leaving the cockpit. All
personnel must ensure that each firing
handle is locked (i.e. fabric safety strap
passed through handle and secured by its
safety pin) before entering the cockpit.
2. If it is necessary to leave the aircraft in
an emergency on the ground special care
must be taken not to foul the seat pan
alternative handle if its safety pin is not in
position.
(a) Mk. 2H seat
(i) A Mk. 2H pilot ejection seat is fitted incorporating
a type ZF harness, headrest, footrests, parachute
container and a seat well for the dinghy and
emergency oxygen supply. A Mk. 8 or 13 parachute
must be used.
(ii) The height maybe adjusted by a lever on the star-
board side of the seat; the harness release is also on
the starboard side.
(iii) A 60 ft./second or 80 ft./second (Martin Baker Mod.
271) ejection gun is fitted. It is important that the
pilot is aware of the type of gun fitted, since this
affects the minimum ejection height (see para
102(f))
(iv) The ejection seat gun is fired by pulling the handle above
the headrest and, when Martin Baker Mod.295 is
embodied, by the alternative firing handle attached
to the forward edge of the seat pan between the
pilot's legs. When either firing handle is operated,
the hood is jettisoned immediately by gas pressure
from the hood jettison cartridge; at the same time a
delay unit at the back of the headrest is started. This
unit withdraws the sear from the seat pan one second
after the handle is pulled. The seat is then ejected
If G conditions necessitate using the seat pan
