Operating characteristics/limitations
Sg 3, fr 7
a.
Slats divided into three segments per
HYD 1

side that are interconnected (bolted
FWD/AFT
Flaps/Slats
together) so they don't transmit wing

loads
b.
Slats raised and lowered by HYD 1
powered actuator in each wing that
SLAT COMPONENTS--SIMPLIFIED
drives rods linked to the inner and
outer slat segments; the center section
is attached to and moves
simultaneously with the two outer
sections (Slats travel in or out on six
slat tracks per slat, two tracks per
segment)
c.
No system to extend slats with HYD 1
failure
d.
Full extension of slats is 15 degrees
(about 5 1/2 inches)
e.
Speed restriction for deployment: 200
KIAS (also speed limit for flying with
slats extended)
NOTE: There is no blow back feature
in the slat hydraulic system.
NOTE: Slats are in an overcenter
locked position when out; even loss of
hydraulic fluid in any or all lines would
not allow slats to retract.
f.
Maneuvering envelope with both slats
extended (symmetrical load condition):
0 to +2.0 g max. Maneuvering
envelope with a split slats
(unsymmetrical load condition): +1.0
to +1.5 g max
