Normal Flight
Familiarization
NOTE: Although the speed brake stabilator interconnect counters pitch transients during speed brake
operation, some pitch adjustment is still required when speed brakes are extended or retracted during
cruise. On extension, a slight nose-up pitch occurs that requires forward stick and retrimming. The
opposite occurs when the speed brakes are retracted. The amount of pitch change in the landing
configuration is negligible.
SLOW FLIGHT EXERCISE
The slow flight exercise familiarizes you with the flight characteristics of the T-45 in the landing
configuration at optimum AOA, but you will practice it at altitude (Figure 7).

PROCEDURES
To perform the slow flight exercise, execute a break, reduce the power to idle, extend speed brakes, and
as your airspeed decreases, increase the nose attitude to maintain altitude. At 200 KIAS, lower the
landing gear and extend full flaps/slats. As the flaps and slats extend, counter the ballooning with a little
forward stick and then begin increasing the nose attitude as the aircraft slows to approach speed. Trim
the aircraft throughout the dirty-up. As airspeed approaches 120 KIAS, increase the power to approxi-
mately 90-94% rpm to maintain optimum AOA. Complete the landing checklist, the AOA/airspeed check,
and trim as necessary. Continue to maintain optimum AOA of 17 units by adjusting the nose attitude. Use
the power as necessary to maintain altitude.
