Pt. 60, App. B
(1) Alternative data sources that may be
used for part or all of a data requirement are
the Airplane Maintenance Manual, the Air-
plane Flight Manual (AFM), Airplane Design
Data, the Type Inspection Report (TIR), Cer-
tification Data or acceptable supplemental
flight test data.
(2) The NSPM recommends that use of the
alternative instrumentation noted in Table
B2F be coordinated with the NSPM prior to
employment in a flight test or data gath-
ering effort.
e. The NSPM position regarding the use of
these alternative data sources, procedures,
and instrumentation is based on three pri-
mary preconditions and presumptions re-
garding the objective data and FTD aero-
dynamic program modeling.
(1) Data gathered through the alternative
means does not require angle of attack
(AOA) measurements or control surface posi-
tion measurements for any flight test. AOA
can be sufficiently derived if the flight test
program insures the collection of acceptable
level, unaccelerated, trimmed flight data.
Angle of attack may be validated by con-
ducting the three basic ‘‘fly-by’’ trim tests.
The FTD time history tests should begin in
level, unaccelerated, and trimmed flight, and
the results should be compared with the
flight test pitch angle.
(2) A simulation controls system model
should be rigorously defined and fully ma-
ture. It should also include accurate gearing
and cable stretch characteristics (where ap-
plicable) that are determined from actual
aircraft measurements. Such a model does
not require control surface position measure-
ments in the flight test objective data for
Level 6 FTD applications.
f. Table B2F is not applicable to Computer
Controlled Aircraft FTDs.
g. Utilization of these alternate data
sources, procedures, and instrumentation
does not relieve the sponsor from compliance
with the balance of the information con-
tained in this document relative to Level 6
FTDs.
h. The term ‘‘inertial measurement sys-
tem’’ allows the use of a functional global
positioning system (GPS).
