PROCEDURE
TROUBLESHOOTING
REFERENCE
FLIGHT CHECKS (CONT)
NOTE
One engine may reach the normal engine
TGT limiter or NG limiting setting before
the other engine. The climb should con-
tinue until the test engine reaches the
TGT limiter or NG limiting at 100% torque.
This does not effect the maximum power
check on the other engine.
Do not exceed 10,000 ft pressure alti-
tude.
(1) The test engine reaches the
normal engine TGT limiter
setting and is identified by
power limiting at the TGT limit.
(2) The test engine reaches a fuel
flow limit as a result of NG
limiting and it is identified by
power limiting at TGTs below
the TGT limit. NG limiting is a
MACH number limitation in the
compressor and it occurs at
colder ambient temperatures.
