HUD indications

Uses AOA information from AOA probe to

present AOA information in with digital and

graphical symbols

AOA bracket "E" shows AOA in relationship to

waterline (T-45A) or velocity vector (T-45C)

F. Actual flight path of T-45 at particular AOA depends on

thrust selected by pilot

Example: A particular thrust setting will maintain

level flight at 17 units AOA, a higher thrust setting

will result in a climb, and a lower thrust setting will

cause the aircraft to descend; a pilot would thus use

AOA to control airspeed and thrust to control altitude
