PART 1II-HANDLING
400 ft. select flap up. At 2,000 ft. ease the nose gently for-
ward to increase speed; if the level out is made too briskly
the target may hit the ground.
NOTE.-The climb to 2,000 ft. is made below safety and
critical speeds. Should engine failure occur, the
target must be jettisoned.
(b) Climb
Climb at 200 knots using 14,100 r.p.m.
(c) General flying
In normal circumstances the Dart can hardly be felt by the
pilot. Speed must not exceed 200 knots before reaching the
operating area and angles of bank used should not exceed
45°. The maximum permissible speed is 275 knots.
(d) Descending
Descend at 200 knots, airbrakes out and 12,000 r.p.m.
These settings will give a rate of descent of 4,000 ft./min.
(e) Dropping
If the Dart is to be dropped in a limited area, it is essential
to have R/T guidance, either from a ground controller or
a formatting aircraft. The lag between manoeuvres of the
aircraft and response of the target is considerable and it is
inadvisable to descend below 2,000 ft. without information
of target behaviour. To release the target, switch on the
camera master switch and press the camera button on the
control column. Release is straightforward and should be
made at a speed of 130-150 knots at a tug height of not
less than 1,000 ft.
NOTE.-The vertical separation between the tug and target
with 4,000 ft. of towing cable varies from 800-
900 feet at 130 knots to 400 ft. at 300 knots.
These figures refer to steady flight conditions and
may vary considerably during speed changes.
(f) If the normal release mechanism fails to operate, the target
can be released by jettisoning the ventral tank.
(g) Loss of target
If the target is lost, the tug speed should be reduced to
200 knots, until the cable has been released. 57
