Flight Instructors Training Procedures _revised AIC_x

vii. Close the other throttle and note that the
same characteristics occur but in the opposite
direction.
viii. Return to twin engine straight and level flight
at cruise power/thrust and speed. Repeat the
previous actions, closing each throttle
alternately and note the flight instrument
indications associated with failure of one
engine.
ix. From straight or level flight, gently throttle
back the left engine whilst using rudder to
prevent yaw (ball in the centre) until maximum
rudder deflection is reached, and ailerons to
maintain lateral level (maximum of 5°).
Use elevator and the power/thrust of the right
engine to maintain altitude (if possible) if
within the capabilities of the aeroplane
performance.
Note that balanced flight and constant
heading can be maintained.
x. Return the aeroplane to twin engine straight
and level flight and cruising power/thrust and
speed.
xi. Gently throttle back the right engine whilst
using rudder to prevent yaw (ball in the
centre) until maximum rudder deflection is
reached, and ailerons to maintain lateral level
(maximum of 5°). Use elevator and the
power/thrust of the left engine to maintain
altitude (if possible).
xii. Return the aeroplane to twin engine straight
and level flight, at cruising power/thrust and
speed.
At this stage the student should practice
maintaining balance, heading and altitude
whilst the instructor closes each throttle
alternately.
Note the “Dead Leg/Dead Engine” method of
identifying which engine has failed.
The student will now practice the
maintenance of balance, heading and altitude
(if possible) whilst at the same time identifying
which engine has been throttled back.
During this practice the engine instrument
Indications of a real engine failure (as against
those seen by shutting down an engine with
the mixture) will be itemised by the instructor.
Point out the MP, RPM, Fuel Flow, Oil Press
and Oil/Cyl Head temps and which will give a
positive indication of engine failure. Flight
and engine instrument indications are of
particular importance during IMC or when only
a partial power/thrust loss of one engine
occurs.
