data collected from specific helicopter flight
tests or other flights the required design
model or data changes necessary to support
an acceptable Proof of Match (POM) should
be generated by the helicopter manufacturer.
(2) For proper validation of the two sets of
data, the helicopter manufacturer should
compare their simulation model responses
against the flight test data, when driven by
the same control inputs and subjected to the
same atmospheric conditions as recorded in
the flight test. The model responses should
result from a simulation where the following
systems are run in an integrated fashion and
are consistent with the design data released
to the flight simulator manufacturer:
(a) Propulsion.
(b) Aerodynamics.
(c) Mass properties.
(d) Flight controls.
(e) Stability augmentation.
(f) Brakes/landing gear.
i. A qualified test pilot should be used to
assess handling qualities and performance
evaluations for the qualification of flight
simulators of new helicopter types.

9. ENGINEERING SIMULATOR - VALIDATION
DATA
a. When a fully validated simulation (i.e.,
validated with flight test results) is modified
due to changes to the simulated helicopter
configuration, the helicopter manufacturer
or other acceptable data supplier must coordinate with the NSPM to supply validation
data from an  - audited -  engineering simulator/simulation to selectively supplement
flight test data. The NSPM must be provided
an opportunity to audit the use of the engineering simulation or the engineering simulator during the acquisition of the data that
will be used as validation data. Audited data
may be used for changes that are incremental in nature. Manufacturers or other
data suppliers must be able to demonstrate
that the predicted changes in helicopter performance are based on acceptable aeronautical principles with proven success history and valid outcomes. This must include
comparisons of predicted and flight test validated data.
b. Helicopter manufacturers or other acceptable data suppliers seeking to use an engineering simulator for simulation validation data as an alternative to flight-test derived validation data, must contact the
NSPM and provide the following:
(1) A description of the proposed aircraft
changes, a description of the proposed simulation model changes, and the use of an integral configuration management process,
including an audit of the actual simulation

model modifications that includes a step-bystep description leading from the original
model(s) to the current model(s).
(2) A schedule for review by the NSPM of
the proposed plan and the subsequent validation data to establish acceptability of the
proposal.
(3) Validation data from an audited engineering simulator/simulation to supplement
specific segments of the flight test data.
c. To be qualified to supply engineering
simulator validation data, for aerodynamic,
engine, flight control, or ground handling
models, a helicopter manufacturer or other
acceptable data supplier must:
(1) Be able to verify their ability to:
(a) Develop and implement high fidelity
simulation models; and
(b) Predict the handling and performance
characteristics of a helicopter with sufficient accuracy to avoid additional flight test
activities for those handling and performance characteristics.
(2) Have an engineering simulator that:
(a) Is a physical entity, complete with a
flight deck representative of the simulated
class of helicopter;
(b) Has controls sufficient for manual
flight;
(c) Has models that run in an integrated
manner;
(d) Had fully flight-test validated simulation models as the original or baseline simulation models;
(e) Has an out-of-the-flight deck visual system;
(f) Has actual avionics boxes interchangeable with the equivalent software simulations to support validation of released software;
(g) Uses the same models as released to the
training community (which are also used to
produce stand-alone proof-of-match and
checkout documents);
(h) Is used to support helicopter development and certification; and
(i) Has been found to be a high fidelity representation of the helicopter by the manufacturer-s pilots (or other acceptable data
supplier), certificate holders, and the NSPM.
(3) Use the engineering simulator to
produce a representative set of integrated
proof-of-match cases.
(4) Use a configuration control system covering hardware and software for the operating components of the engineering simulator.
(5) Demonstrate that the predicted effects
of the change(s) are within the provisions of
sub-paragraph  - a -  of this section, and confirm that additional flight test data are not
required.
d. Additional Requirements for Validation
Data
(1) When used to provide validation data,
an engineering simulator must meet the simulator standards currently applicable to
