Introduction to ACM
c.
Wing loading--combat weight/wing area
(1) Aircraft with higher wing loading has larger turn radius
and slower turn rate
(2) Aircraft with lower wing loading has smaller turn radius
and faster turn rate
2.
Variable factors 6.7.2.4
a.
Altitude--provides potential energy (PE) for maneuvering
b.
Airspeed--kinetic energy (KE): as altitude increases, TAS
increases for constant KIAS airspeed
c.
Angle of attack
(1) At a given AOA, coefficient of lift and drag is constant
regardless of airspeed, gross weight, and altitude
(2) In an engaging turn (energy sustaining turn),
corresponding AOA reflects optimum lift to drag ratio
NOTE: Optimum AOA's are explained in the following
energy management section.
d.
G loading
(1) Ratio of lift to weight
(2) In turns or direction changes, lift must exceed weight,
and g loads greater than 1 g are necessary
(3) At constant TAS, as g is increased so does AOA
(4) Radial g--determines turn radius and rate
(5) Instantaneous g
(a) Maximum lift a wing may generate at a given
airspeed
(b) Dependent upon aircraft airframe/wing
