the speeds that are determined during this exercise.
(D) Feathering and unfeathering:
a) minimum heights for practising feathering and unfeathering drills;
and
b) engine-handling precautions (overheating, icing conditions,
priming, warm-up, method of simulating an engine failure: refer to
the aircraft engine manual, service instructions, and bulletins).
(E) Engine failure procedure:
a) once control is maintained, the phase of operation and the aircraft
type determine in which order the procedures should be followed;
and
b) the flight phase should be:
1) in cruising flight; or
2) a critical phase, e.g. immediately after take-off or during
approach to landing or during a go-around.
(F) Aircraft type:
Variations in the order of certain drills and checks inevitably occur due to
differences between aeroplane types and perhaps between models of
the same aeroplane type. The AFM should be consulted to establish the
exact order of the related procedures.
For example, one AFM may call for the raising of flaps and landing gear
before feathering, whereas another AFM may recommend feathering as
a first step. The reason for this latter procedure may be that some
engines cannot be feathered if RPM drop below a certain figure.
However, in some aeroplanes, the raising of the landing gear may create
more drag during retraction due to the transient position of the landing
gear doors, and as a result, retraction should be avoided until feathering
is completed and propeller drag reduced.
Therefore, the order in which the drills and checks are presented under
immediate and subsequent actions in this syllabus should be
considered as general guidance only; the exact order of precedence is
determined by reference to the AFM for the specific aeroplane type used
in the course.
(G) In-flight engine failure during cruising or other flight phase not including
take-off or landing:
a) immediate actions:
1) control of the aircraft;
2) recognition of asymmetric condition;
3) identification and confirmation of failed engine:
i. idle leg = idle engine; and
ii. closing of throttle or pulling back of power lever, as
appropriate, for confirmation;
4) identification of failure cause and fire check:
i. typical reasons for failure; and
ii. methods of rectification; and
5) feathering decision and procedure:
i. reduction of other drag;
ii. need for speed but not haste; and
iii. use of rudder trim;
b) subsequent actions:
1) operating engine:
i. temperature, pressure, and power;
ii. remaining services;
iii. electrical load: assess and reduce, as necessary;
iv. effect on power source for air-driven instruments;
v . landing gear; and
vi. flaps and other services;
2) replanning of the flight:
i. ATC and weather;
ii. terrain clearance, SE cruising speed; and
iii. decision to divert or continue;
3) fuel management: best use of remaining fuel;
4) dangers of restarting damaged engine;
5) action if unable to maintain altitude: effect of altitude on
available power;
6) effects on performance;
7) effects on available power and required power;
8) effects on various airframe configurations and propeller
settings;
