PART 1-DESCRIPTIVE
(b) All leads incorporate quick releases which are auto-
matically broken on ejection.
(c) As the seat is ejected a static line readies the barostatic
time-delay mechanism. When the free descent reaches
10,000 ft. or at once if ejection has taken place below that
height and provided that the G-stop has not operated,
the barostat removes an obstruction from the gear train
of the mechanism allowing it to operate.
(d) After three seconds (11 with G-stop fitted) the seat
harness is released, the seat-stabilising drogues are freed
and by a connecting lifting line the face screen is dis=
connected and the parachute deployed. The occupant is
momentarily prevented from leaving the seat by two
restraining straps until deployment of the parachute lifts
him clear of the seat.
