FREE-ELEVATOR FACTOR
When the elevator is free, the lift-curve slope is given by (2.6,4b), that is,
(2.6,6)
The factor in parentheses is the free elevator factor, and normally has a value less than unity. When the elevator is part of the tail, the floating angle can be related to a„ viz for b0 = 0

Cht, = b{a, + b28„tm: + b38, = 0
and the tail lift coefficient is
