a. Typically, a helicopter manufacturer’s
approved final data for performance, han-
dling 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. Con-
sequently, it may be necessary to use pre-
liminary data provided by the helicopter
manufacturer for interim qualification of
flight simulators.
b. In these cases, the NSPM may accept
certain partially validated preliminary heli-
copter 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 qualifica-
tion based on preliminary data should con-
sult the NSPM to make special arrange-
ments for using preliminary data for flight
simulator qualification. The sponsor should
also consult the helicopter and flight simu-
lator 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 heli-
copter manufacturers. Each helicopter man-
ufacturer’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 an-
other manufacturer’s program or even the
same manufacturer’s program for a different
helicopter. Therefore, there cannot be a pre-
scribed invariable procedure for acceptance
of preliminary data; instead there should be
a statement describing the final sequence of
events, data sources, and validation proce-
dures agreed by the simulator sponsor, the
helicopter manufacturer, the flight simu-
lator manufacturer, and the NSPM.

: A description of helicopter manufac-
turer-provided data needed for flight simu-
lator modeling and validation is to be found
in the ‘‘Royal Aeronautical Society Data
Package Requirements for Design and Per-
formance Evaluation of Rotary Wing Syn-
thetic Training Devices.’’
e. The preliminary data should be the man-
ufacturer’s best representation of the heli-
copter, with assurance that the final data
will not deviate significantly from the pre-
liminary 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 meth-
od 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 advan-
tage for early flight simulator validation.
Certain critical tests that would normally be
done early in the helicopter certification
program should be included to validate es-
sential pilot training and certification ma-
neuvers. 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 manu-
facturer should include provisions for gen-
eration of very early flight tests results for
flight simulator validation.
