BEGIN INFORMATION
1. DISCUSSION
a. If relevant winds are present in the objective data, the wind vector (magnitude and
direction) should be noted as part of the data
presentation, expressed in conventional terminology, and related to the runway being
used for the test.
b. The format for numbering the objective
tests in Appendix C of this part, Attachment
2, Table C2A, and the objective tests in Appendix D of this part, Attachment 2, Table
D2A, is identical. However, each test required for FFSs is not necessarily required
for FTDs, and each test required for FTDs is
not necessarily required for FFSs. When a
test number (or series of numbers) is not required, the term  - Reserved -  is used in the
table at that location. Following this numbering format provides a degree of commonality between the two tables and substantially reduces the potential for confusion when referring to objective test numbers for either FFSs or FTDs.
c. A Level 4 FTD does not require objective
tests and is not addressed in the following
table.

2. TEST REQUIREMENTS
a. The ground and flight tests required for
qualification are listed in Table D2A Objective Evaluation Tests. Computer generated
FTD test results must be provided for each
test except where an alternate test is specifically authorized by the NSPM. If a flight
condition or operating condition is required
for the test but does not apply to the helicopter being simulated or to the qualification level sought, it may be disregarded (e.g.,
engine out climb capability for a single-engine helicopter). Each test result is compared against the validation data described

in Section 60.13, and in Appendix B of this part. The
results must be produced on an appropriate
recording device acceptable to the NSPM
and must include FTD number, date, time,
conditions, tolerances, and appropriate dependent variables portrayed in comparison
to the validation data. Time histories are required unless otherwise indicated in Table
D2A. All results must be labeled using the
tolerances and units given.
b. Table D2A in this attachment sets out
the test results required, including the parameters, tolerances, and flight conditions
for FTD validation. Tolerances are provided
for the listed tests because mathematical
modeling and acquisition and development of
reference data are often inexact. All tolerances listed in the following tables are applied to FTD performance. When two tolerance values are given for a parameter, the
less restrictive may be used unless otherwise
indicated. In those cases where a tolerance is
expressed only as a percentage, the tolerance
percentage applies to the maximum value of
that parameter within its normal operating
range as measured from the neutral or zero
position unless otherwise indicated.
c. Certain tests included in this attachment must be supported with an SOC. In
Table D2A, requirements for SOCs are indicated in the  - Test Details -  column.
d. When operational or engineering judgment is used in making assessments for
flight test data applications for FTD validity, such judgment must not be limited to a
single parameter. For example, data that exhibit rapid variations of the measured parameters may require interpolations or a
 - best fit -  data section. All relevant parameters related to a given maneuver or flight
condition must be provided to allow overall
interpretation. When it is difficult or impossible to match FTD to helicopter data
throughout a time history, differences must
be justified by providing a comparison of
other related variables for the condition
being assessed.
e. The FTD may not be programmed so
that the mathematical modeling is correct
only at the validation test points. Unless
noted otherwise, tests must represent helicopter performance and handling qualities at
operating weights and centers of gravity
(CG) typical of normal operation. If a test is
