Description / Abstract:
Purpose:
The purpose of this standard is to provide a method of evaluating
helicopter fuel economy which
accounts for the significant technical variables in helicopter and
powerplant design.
Helicopter Operational Modes:
This method evaluates helicopter fuel economy for two modes of
operation: best range and maximum
endurance. The best range mode is important for patrol, inspection,
search or cargo delivery
missions. The maximum endurance mode is important for traffic control,
antisubmarine warfare or
other loiter-type missions.
Data:
The helicopter Pilot's Handbook is the only data source required. The
Best Range Chart, Maximum
Endurance Chart and the specified helicopter weight empty are used.
