do not exceed 239 knots until slats retract to
midrange.
Note: Slats will extend beyond midrange when
airspeed is below 246 knots. For go-around,

Note: Slats will extend beyond midrange when
airspeed is below 256 knots. For go-around,
do not exceed 256 knots until slats retract to
midrange.
Notes:Use flaps 20 and VREF 30 + 20 for landing.
This allows higher approach speeds to
improve airplane maneuvering
characteristics.
Crosswind limit for landing is 20 knots.
Roll rate may be reduced in flight.
Speedbrake effectiveness may be reduced in
flight and during landing.
Do not arm the speedbrake lever. This
prevents inadvertent inflight extension.
Manually extend the speedbrakes after
landing.
For go–around, do not exceed the gear
EXTEND limit speed (270 knots/.82 Mach).
