FLAPS SYSTEM

driven by an electric motor through a gear-
box mounted on the forward side of the rear
spar (Figure 15-1). The motor incor porates
a dynamic braking system through the use
of two sets of motor windings. This system
helps to prevent overtravel of the flaps. The
gearbox drives four flexible driveshafts, each
of which is connected to a jackscrew actua-
tor at each flap.
The flaps are operated by a sliding lever lo-
cated just below the condition levers on the
pedestal (Figure 15-2). Flap travel, from 0%
(UP) to 100% (DOWN), is registered at 20,
APPROACH, 40, 60, and 80 and DOWN in
percentage of travel on an electric indicator
on top of the pedestal (Figure 15-3).
