T-45A UJPT, ADV, & IUT ACMFP-01
Introduction to ACM
(c) Displayed on velocity load factor (Vn) diagram
(d) ACM relationship--used to generate maximum
rate of turn
(6) Sustained g
(a) A function of aircraft thrust available with respect
to wing loading
(b) Maximum g capability in level turn with constant
airspeed
(c) Increases with higher thrust-to-weight ratio
(d) ACM relationship--to maintain energy throughout
an engagement
e.
Turn radius
(1) Distance that aircraft displaces laterally in turn
(2) Dependent on TAS and g with constant altitude--
TAS2/g
(3) TAS has a greater effect on turn radius than rate
(4) Sustainability--given two aircraft at constant TAS, the
aircraft that can sustain most g will have the smallest
turn radius
f.
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
