performance varies widely with type of airplane, weight, tem-
perature, altitude, and airplane configuration, the climb gra-
dient (altitude gain or loss per mile) may be marginal - or
even negative - under some conditions. Study the Pilot's
Operating Handbook and FAA Approved Airplane Flight
Manual for your airplane and know what performance to
expect with one engine out.
ONE-ENGINE-INOPERATIVE
BEST
ANGLE-OF-CLIMB SPEED
(VXSE)
VXSE is used only to clear obstructions during initial climb-
out as it ,givesthe greatest altitude gain per unit of horizon-
tal distance.
It provides less engine cooling and requires
more rudder control input than
VYSE.
SINGLE ENGINE SERVICE CEILING
The single engine service ceiling is the maximum altitude at
which an airplane
will climb at a rate of at least 50 feet per
minute in smooth air, with one engine inoperative.
The single engine service ceiling chart should be used dur-
ing flight planning to determine whether the airplane, as
loaded, can maintain the Minimum En Route Altitude (MEA)
if IFR, or terrain clearance if VFR, following an engine fail-
ure.
BASIC SINGLE ENGINE PROCEDURES
Know and follow, to the letter, the single-engine emergency
procedures specified in your Pilot's Operating Handbook
and FAA Approved Airplane Flight Manual for your specific
make and model airplane. However, the basic fundamentals
of all the procedures are as follows:
1. Maintain airplane control and airspeed at all times.
THIS IS CARDINAL RULE NUMBER ONE.
2. Usually, apply maximum power to the operating engine.
