T-45A/C TS, E2-C2, ADV & IUT Aero-03
Slow-Speed Flight, Stall and Spin, and AOA System
III. Angle of attack (AOA) system 1.7.1.4.1.3
Sg 3, fr 2
Lesson Organization
A. Provides the pilot with information necessary to obtain
optimum aircraft performance, particularly at low
SLOW-SPEED FLIGHT,
airspeeds and high AOAs
STALL AND SPIN,
AND AOA SYSTEM
B. Used primarily during the approach and landing phases
* Slow-speed flight
* Stall and spin
of flight
* Angle of attack
(AOA) system
NOTE: Aerodynamically, AOA is indicated airspeed
(IAS). By controlling the AOA, the pilot controls IAS.
C. Indicates for each AOA a percentage of the maximum lift

Theory
1.
During flight at a constant AOA (approach and
landings), a constant coefficient of lift is maintained
NOTE: Recall that as aircraft weight decreases, so
must lift (basic lift formula). This is accomplished in
the T-45 by holding AOA constant and reducing IAS
as weight is reduced.
2.
Flying correct AOA and maintaining proper
glideslope (using power) will obtain optimum landing
speed, landing attitude, and sink rate
a.
Reduces possibility of in-flight engagements
b.
Reduces overstressing of the aircraft
D.
Use during landings is more desirable than use of the
pitot-static system
1.
AOA more accurately measures aircraft
performance than pitot-static system at low speeds;
as speed decreases, position error increases
2.
Optimum landing AOA is not affected by weight,
bank angle, g load, or density altitude; IAS is
affected
