T-45C TS, ADV & IUT ENG-13
Flight Control System
(2) Function: improve stall margin and slow
speed flight characteristics
b.
Slat actuators
(1) Location: one actuator attached to front
spar of each wing
(2) Function
(a) Powered by HYD 1, extends/retracts
slats by mechanical linkage
(b) Normal operation of actuators main-
tains slat symmetry during extension/
retraction
(c) Synchro cable between actuators will
maintain slats within 2 degrees of each
other if normal system fails
c.
Thermal relief valves
(1) Location: incorporated into slat selector
assembly
(2) Function
(a) Protects hydraulic lines against
thermal expansion of hydraulic fluid
3.
Cockpit controls/switches/indicators
Sg 3, fr 7
a.
FLAPS/SLATS lever
Fig 14: Slat Controls
and Indicators
(1) Location: inboard of the throttle quadrant
(2) Function: three position control with
detents for selecting flaps/slats UP, 1/2,
or DN. Forward and aft controls are
