ENGINE CONDITION TREND MONITORING
Pratt & Whitney Canada New Generation Engine Condition Trend Monitoring
System is a system of recording engine instrument reading, correcting the
readings for ambient conditions, and comparing actual engine operation to
typical engine operating characteristics.
Engine instrument recording is provided through the Garmin G1000. The
G1000 records the following engine parameters:
• Inter Turbine Temperature (ITT)
• Torque
• Gas Generator RPM (
)
• Fuel Flow
• Indicated Outside Air Temperature
• Altitude
• Indicated Airspeed (KIAS)
The recorded engine parameters may be downloaded periodically from
the top card slot of the PFD and uploaded to Pratt & Whitney Canada’s
WebECTM System for trend monitoring.
For more information concerning engine condition trend monitoring, refer to
Pratt & Whitney Canada “Service Information Letter No. PT6A-122.”
8-3 ALTERATIONS OR REPAIRS
It is important that the FAA is contacted prior to any alterations on the
airplane, to ensure that the airworthiness is not violated. Major alterations or
repairs to the airplane must be accomplished by FAA authorized personnel.
8-4 GROUND HANDLING
TOWING
The airplane is most easily and safely maneuvered by hand with the tow-bar
attached to the nose wheel. The tow bar may be stowed in the aircraft cabin
baggage compartment. Moving the airplane by hand requires one individual
to steer the airplane with the tow-bar, assisted by personnel pushing at the
wing struts.
During any towing operation, especially when conducted with the assistance
of a powered vehicle, do not exceed the nose gear turning limits of 55° either
side of center, as shown by the steering limit marks.
CAUTION: Do not push or pull the airplane using the propeller blades
or ight control surfaces.
