Engineering Review
2.
Slat system
a.
System overview: augments lift to
wing when extended, decreasing stall
speed and increasing aircraft control
and stability during slow speed flight
b.
Control surface components
(1) Slat panels
(2) Slat actuators
(3) Pressure/thermal relief valves
c.
Cockpit controls/switches/indicators
d.
FLAPS/SLATS lever
(1) UP: slats retracted
(2) 1/2 or DOWN: slats fully extended
e.
SLAT position indication: SLATS
caution light illuminated when slats not
in selected position, split slats, slat
extension attempted above 217 KIAS,
or when accelerating to above
217 KIAS with slats extended
f.
Operating characteristics/limitations
(1) Slats raised and lowered by
HYD 1 powered actuators in each
wing that drive push rods linked to
the inner and outer slat segments
(2) Normal operation of actuators
maintains slats symmetrical during
extension/retraction
(3) Backup synchro cable between
actuators if normal system fails
