LECTURE NOTES
Explain: Full trim and no trim conditions
MAX 90% rpm above 20,000 ft
MAX 95% rpm below 20,000 ft
CAUTION: In the
unlikely event of an
ECA failure in a full trim
condition, fuel flow will
be reduced; the EGT
and rpm will decrease,
and the thrust available
will be governed by the
maximum rpm
obtained. The thrust
may be reduced by as
much as one third of
the normal full throttle
value. Very low idle
rpm may occur, and the
throttle must be
handled carefully to
avoid stall or flameout.
