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
