WEIGHT (W)
i. Couples.
ii. Nosedown – Pitch.
LIFT (L)
i. Formula.
ii. Equal and opposite to weight.
iii. Speed/Attitude relationship.
THRUST (T)
i. Power off – resultant of weight and lift.
ii. Path of glide = T - D
W
iii. Effect of power during the descent related to:
a. Angle of descent.
b. Rate of descent.
c. Speed/Attitude relationship.
DRAG (D)
i. Discuss graph for total drag.
ii. Effect of variations in drag on the glide angle:
a. Speed.
b. Aircraft configuration.
c. Propeller pitch.
8. REFER TO THE APPROPRIATE GRAPHS AND DISCUSS
i. MINIMUM GLIDE ANGLE
DEFINITION
To produce the greatest proportion of glide distance to height lost and will result in the
maximum range glide.
FORMULA: Sin of glide angle =
SPEED
For power off = D
W
++
T - D
W
This relationship shows that the minimum angle of glide is obtained at minimum total
drag. This coincides with maximum lift/drag ratio.
ii. MINIMUM RATE OF DESCENT
DEFINITION
Without any power this will occur at the angle of attack and airspeed which together
produce a condition of the minimum power required resulting in a minimum rate of
descent and maximum airborne time.
