Total energy (TE) - P-12760014

T-45C TS, ADV & IUT ACMFP-01

Introduction to ACM

(4) Sustainability — given two aircraft at

constant TAS, the aircraft that can sustain

most G will have the smallest turn radius

Turn rate

(1) Equates to pitch rate in horizontal plane

(2) Dependent on TAS and G with constant

altitude (G/TAS)

(3) Given two aircraft at a constant TAS, the

aircraft that can sustain most G will have

fastest turn rate

(4) Instantaneous — maximum available turn

rate at any given airspeed without regard to

energy sustainability

Total energy (TE) — combination of aircraft’s

altitude (PE) and airspeed (KE)

NOTE: Determining the TE advantage

determination for a given aircraft is difficult because

of the possible speed differences between fighters.

Specific excess power (Ps) — measures ability

of aircraft to increase its energy state by using

excess thrust

Cornering speed

NOTE: Cornering speed has previously been

referred to as maneuvering speed.
