T-45A UJPT, E2-C2, ADV, & IUT Eng-26
Engineering Review
(3) FLAP position indicator
d.
Operating characteristics/limitations
(1) Flaps raised and lowered via
single actuator
(2) Powered by HYD 1 via push-pull
control rods and bellcrank levers
(3) Extension of flaps via wheel
brake/emergency flap accumulator
in event of HYD 1 failure
(4) Forward and aft cockpits FLAPS/
SLATS switches are mechanically
interconnected
(5) Full extension of flaps is approxi-
mately 50 degrees, half approxi-
mately 25 degrees
(6) EMERG FLAPS switch fully ex-
tends flaps by commanding wheel
brake/emergency flap accumulator
to discharge; no flap extension if
accumulator pressure is less than
2,200 psi
(7) Maximum speed for full or one-
half extension is 200 KIAS
(8) Maneuvering envelope with flaps
extended: 0 to +2.0 g max; ma-
neuvering envelope with an asym-
metrical load on wing pylons:
+1.0 to +1.5 g max
NOTE: A split flap condition is
highly unlikely in the T-45A; how-
ever, it is not impossible and
would be very dangerous should it
occur.
