event of an engine failure. The pilot must be prepared to use
assertive control input to maintain airplane control following
an engine failure.
INTENTiONAL ONE-ENGiNE INOPERATIVE
SPEED (VSSE)
VSSE is specified by the airplane manufacturer and is the
minimum speed at which to perform intentional engine cuts.
Use of
VSSE is intended to reduce the accident potential
from loss of control after engine cuts at or near minimum
control speed.

demonstrations are necessary in train-
ing but should only be made at safe altitude above the ter-
rain and with power reduction on one engine made at or
above

BEST
RATE-OF-CLIMB SPEED (VYSE)
VYSE is designated by the blue radial on the airspeed indi-
cator.
VYSE delivers the greatest gain in altitude in the short-
est possible time, and is based on the following criteria:
• Critical engine inoperative, and its propeller in the mini-
mum drag position.
• Operating engine set at not more than the maximum
continuous power.
• Landing gear retracted.
• Wing flaps up.
• Cowl flaps as required for engine cooling.
.•
Airplanes flown at recommended bank angle (up to 50
into operating engine).
Drag caused by a windmilling propeller, extending landing
gear, or flaps in the landing position, will severely degrade
or destroy single engine climb performance. Since climb
