Slow-Speed Flight, Stall and Spin, and AOA System

T-45A/C TS, E2-C2, ADV & IUT Aero-03

MOTIVATION

The margin for error in a high performance aircraft flying straight

Sg 0, fr 5

and level at 500 KIAS and 25,000 ft is much larger than the

Slow Flight

margin for error as you approach the carrier all dirtied up at

120 KIAS with 500 ft of altitude. Most pilot-induced accidents

occur during takeoff, approach, and landing; so it is critical that

you understand the aerodynamics of slow-speed flight

maneuvering.

OVERVIEW

This lesson is designed to prepare you for slow-speed flight in a

high performance aircraft.

In this lesson we will be studying:

Slow-speed flight

Stalls and spins

Angle-of-attack (AOA) system

REFRESHER

Recall that:

Changing the wing's geometry to a lower camber, a lower

thickness-to-chord ratio, and a lower aspect ratio and adding

sweepback will lower the total drag of the wing, but the wing

will require a higher AOA to produce the same amount of lift

as a wing of higher aspect ratio. At high speeds, we benefit

from these changes with better performance and maneuver-

ability; however, the high AOA and slow-speed flight

characteristics will be degraded.
