e. The preliminary data should be the manufacturer-s best representation of the airplane, with assurance that the final data will
not significantly deviate from the preliminary estimates. Data derived from these predictive or preliminary techniques should be
validated against 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 airplane 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 airplane 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 airplane certification program should be included to validate essential pilot training and certification maneuvers. These include cases where
a pilot is expected to cope with an airplane
failure mode or an engine failure. Flight test
data that will be available early in the flight
test program will depend on the airplane
manufacturer-s flight test program design
and may not be the same in each case. The
flight test program of the airplane manufacturer should include provisions for generation of very early flight test results for
flight simulator validation.
f. The use of preliminary data is not indefinite. The airplane manufacturer-s final data
should be available within 12 months after
the airplane-s first entry into service or as
agreed by the NSPM, the simulator sponsor,
and the airplane 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 or from other
approved sources. Initial airplane systems
data should be updated after engineering
tests. Final airplane systems data should
also be used for flight simulator programming and validation.
g. Flight simulator avionics should stay
essentially in step with airplane avionics
(hardware and software) updates. The permitted time lapse between airplane 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
airplane 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
data collected from specific airplane 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 airplane manufacturer.
(2) For proper validation of the two sets of
data, the airplane 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; and
(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 airplane 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 airplane
configuration, the airplane manufacturer or
other acceptable data supplier must coordinate with the NSPM if they propose 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 engineering simulation or the engineering simulator used to generate the validation data.
Validation data from an audited engineering
simulation 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 aircraft performance are based on acceptable
aeronautical principles with proven success
