2. Engine inoperative flight using ailerons alone
requires an 8 - 10° bank angle towards the operative
engine. [Figure 12-17] This assumes no
rudder input. The ball will be displaced well
towards the operative engine. The result is a
large sideslip towards the operative engine.
Climb performance will be greatly reduced by
the large sideslip.

Excessive bank engine-out flight.

3. Rudder and ailerons used together in the proper
combination will result in a bank of approximately
2° towards the operative engine. The

ball will be displaced approximately one-third
to one-half towards the operative engine. The
result is zero sideslip and maximum climb performance.
[Figure 12-18] Any attitude other
than zero sideslip increases drag, decreasing
performance. Vmc under these circumstances
will be higher than published, as less than the
5° bank certification limit is employed.

Zero sideslip engine-out flight.
Figure 12-18. Zero sideslip engine-out flight.

The precise condition of zero sideslip (bank angle and
ball position) varies slightly from model to model, and
with available power and airspeed. If the airplane is
not equipped with counter-rotating propellers, it will
also vary slightly with the engine failed due to P-factor.
The foregoing zero sideslip recommendations apply to
reciprocating engine multiengine airplanes flown at
VYSE with the inoperative engine feathered. The zero
sideslip ball position for straight flight is also the zero
sideslip position for turning flight.
