Tactical Formation
b.
Airspeed - kinetic energy
(1) As altitude increases, TAS increases for constant IAS
(2) As TAS increases, turn radius increases
c.
AOA
(1) At a specific AOA, coefficient of lift (CL) and coefficient
of drag (CD) for a given wing remain constant
regardless of airspeed, gross weight, g, and altitude
(2) In an energy-sustaining turn, optimum AOA reflects
maximum lift-to-drag ratio; every other maneuver has
some optimum constant AOA which matches lift to
drag to yield desired performance
d.
G
(1) Ratio of lift to weight
(2) For turns or direction changes, lift must exceed weight,
and g loads greater than 1 g are necessary
(3) As g increases, so does AOA
e.
Turn radius - distance that aircraft displaces laterally in turn
(TAS2/g)
(1) Sustainability - aircraft that can sustain most g at
constant TAS will have smallest turn radius
(2) Dependent on TAS and g with constant altitude
(3) TAS has greater effect on turn radius than rate
f.
Turn rate - equates to pitch rate in horizontal plane (g/TAS)
(1) Instantaneous - maximum available turn rate at any
given airspeed without regard to energy sustainability
(2) Aircraft that can sustain most g will have greatest turn
rate
(3) Dependent on TAS and g
