T-45C TS, ADV & IUT ENG-13
Flight Control System
Extension of flaps via wheel brake/emergency
flap accumulator in event of HYD 1 failure
Full extension of flaps is approximately
50 degrees, half approximately 25 degrees
EMER FLAPS switch fully extends flaps if
adequate accumulator pressure is available.
No flap extension if accumulator pressure is
below 2200 psi.
Speed restriction for deployment: 200 KIAS
Maneuvering envelope with both flaps extended
(symmetrical): 0 to +2.0 g max. Maneuvering
envelope with a split flap (unsymmetrical)
condition: +1.0 to +1.5 g max
NOTE: Due to the design of the T-45 a split
flap condition is highly unlikely. Be advised that
this is not an impossibility and would be a very
dangerous situation should it occur.
