(3) Differences between the two sets of results, other than variations attributable to
repeatability issues that cannot be explained, should be investigated.
(4) The flight simulator should retain the
ability to over-plot both automatic and manual validation test results with reference
data.

BEGIN INFORMATION
b. It has become standard practice for experienced simulator manufacturers to use
modeling techniques to establish data bases
for new simulator configurations while
awaiting the availability of actual flight test
data. The data generated from the aerodynamic modeling techniques is then compared to the flight test data when it becomes
available. The results of such comparisons
have become increasingly consistent, indicating that these techniques, applied with
the appropriate experience, are dependable
and accurate for the development of aerodynamic models for use in Level A and Level
B simulators.
c. Based on this history of successful comparisons, the NSPM has concluded that those
who are experienced in the development of
aerodynamic models may use modeling techniques to alter the method for acquiring
flight test data for Level A or Level B simulators.
d. The information in Table A2E (Alternative Data Sources, Procedures, and Instrumentation) is presented to describe an acceptable alternative to data sources for simulator modeling and validation and an acceptable alternative to the procedures and
instrumentation traditionally used to gather
such modeling and validation data.
(1) Alternative data sources that may be
used for part or all of a data requirement are
the Airplane Maintenance Manual, the Airplane Flight Manual (AFM), Airplane Design
Data, the Type Inspection Report (TIR), Certification Data or acceptable supplemental
flight test data.

(2) The sponsor should coordinate with the
NSPM prior to using alternative data
sources in a flight test or data gathering effort.
e. The NSPM position regarding the use of
these alternative data sources, procedures,
and instrumentation is based on the following presumptions:
(1) Data gathered through the alternative
means does not require angle of attack
(AOA) measurements or control surface position measurements for any flight test. However, AOA can be sufficiently derived if the
flight test program ensures the collection of
acceptable level, unaccelerated, trimmed
flight data. All of the simulator time history
tests that begin in level, unaccelerated, and
trimmed flight, including the three basic
trim tests and  - fly-by -  trims, can be a successful validation of angle of attack by comparison with flight test pitch angle. (Note:
Due to the criticality of angle of attack in
the development of the ground effects model,
particularly critical for normal landings and
landings involving cross-control input applicable to Level B simulators, stable  - fly-by - 
trim data will be the acceptable norm for
normal and cross-control input landing objective data for these applications.)
(2) The use of a rigorously defined and fully
mature simulation controls system model
that includes accurate gearing and cable
stretch characteristics (where applicable),
determined from actual aircraft measurements. Such a model does not require control surface position measurements in the
flight test objective data in these limited applications.
f. The sponsor is urged to contact the
NSPM for clarification of any issue regarding airplanes with reversible control systems. Table A2E is not applicable to Computer Controlled Aircraft FFSs.
g. Utilization of these alternate data
sources, procedures, and instrumentation
(Table A2E) does not relieve the sponsor
from compliance with the balance of the information contained in this document relative to Level A or Level B FFSs.
h. The term  - inertial measurement system -  is used in the following table to include
the use of a functional global positioning
system (GPS).
i. Synchronized video for the use of alternative data sources, procedures, and instrumentation should have:
(1) Sufficient resolution to allow magnification of the display to make appropriate
measurement and comparisons; and
(2) Sufficient size and incremental marking to allow similar measurement and comparison. The detail provided by the video
should provide sufficient clarity and accuracy to measure the necessary parameter(s)
to at least 1-2 of the tolerance authorized for
the specific test being conducted and allow
