8. ADDITIONAL INFORMATION ABOUT FLIGHT
SIMULATOR QUALIFICATION FOR NEW OR DERIVATIVE HELICOPTERS
a. Typically, a helicopter manufacturer-s
approved final data for performance, handling qualities, systems or avionics is not
available until well after a new or derivative
helicopter has entered service. However,
flight crew training and certification often
begins several months prior to the entry of
the first helicopter into service. Consequently, it may be necessary to use preliminary data provided by the helicopter
manufacturer for interim qualification of
flight simulators.
b. In these cases, the NSPM may accept
certain partially validated preliminary helicopter and systems data, and early release
( - red label - ) avionics data in order to permit
the necessary program schedule for training,
certification, and service introduction.
c. Simulator sponsors seeking qualification based on preliminary data should consult the NSPM to make special arrangements for using preliminary data for flight
simulator qualification. The sponsor should
also consult the helicopter and flight simulator manufacturers to develop a data plan
and flight simulator qualification plan.
d. The procedure to be followed to gain
NSPM acceptance of preliminary data will
vary from case to case and between helicopter manufacturers. Each helicopter manufacturer-s new helicopter development and
test program is designed to suit the needs of
the particular project and may not contain
the same events or sequence of events as another manufacturer-s program or even the
same manufacturer-s program for a different
helicopter. Therefore, there cannot be a prescribed invariable procedure for acceptance
of preliminary data; instead there should be
a statement describing the final sequence of
events, data sources, and validation procedures agreed by the simulator sponsor, the
helicopter manufacturer, the flight simulator manufacturer, and the NSPM.
NOTE: A description of helicopter manufacturer-provided data needed for flight simulator modeling and validation is to be found
in the  - Royal Aeronautical Society Data
Package Requirements for Design and Performance Evaluation of Rotary Wing Synthetic Training Devices. - 
e. The preliminary data should be the manufacturer-s best representation of the helicopter, with assurance that the final data
will not deviate significantly from the preliminary estimates. Data derived from these
predictive or preliminary techniques should
be validated by available sources including,
at least, the following:
(1) Manufacturer-s engineering report. The
report should explain the predictive method
used and illustrate past success of the method on similar projects. For example, the

manufacturer could show the application of
the method to an earlier helicopter model or
predict the characteristics of an earlier
model and compare the results to final data
for that model.
(2) Early flight test results. This data is
often derived from helicopter certification
tests and should be used to maximum advantage for early flight simulator validation.
Certain critical tests that would normally be
done early in the helicopter certification
program should be included to validate essential pilot training and certification maneuvers. These tests include cases where a
pilot is expected to cope with a helicopter
failure mode or an engine failure. The early
data available will depend on the helicopter
manufacturer-s flight test program design
and may not be the same in each case. The
flight test program of the helicopter manufacturer should include provisions for generation of very early flight tests results for
flight simulator validation.
f. The use of preliminary data is not indefinite. The helicopter manufacturer-s final
data should be available within 12 months
after the helicopter first entry into service
or as agreed by the NSPM, the simulator
sponsor, and the helicopter manufacturer.
When applying for interim qualification
using preliminary data, the simulator sponsor and the NSPM should agree on the update program. This includes specifying that
the final data update will be installed in the
flight simulator within a period of 12 months
following the final data release, unless special conditions exist and a different schedule
is acceptable. The flight simulator performance and handling validation would then be
based on data derived from flight tests. Initial helicopter systems data should be updated after engineering tests. Final helicopter systems data should also be used for
flight simulator programming and validation.
g. Flight simulator avionics should stay
essentially in step with helicopter avionics
(hardware and software) updates. The permitted time lapse between helicopter and
flight simulator updates should be minimal.
It may depend on the magnitude of the update and whether the QTG and pilot training
and certification are affected. Differences in
helicopter and flight simulator avionics
versions and the resulting effects on flight
simulator qualification should be agreed between the simulator sponsor and the NSPM.
Consultation with the flight simulator manufacturer is desirable throughout the qualification process.
h. The following describes an example of
the design data and sources that might be
used in the development of an interim qualification plan.
(1) The plan should consist of the development of a QTG based upon a mix of flight
test and engineering simulation data. For
