a. Sponsors are not required to use the al-

ternative data sources, procedures, and in-
strumentation. However, a sponsor may 
choose to use one or more of the alternative 
sources, procedures, and instrumentation de-
scribed in Table B2F.

b. It has become standard practice for ex-

perienced FTD manufacturers to use such 
techniques as a means of establishing data 
bases for new FTD configurations while 
awaiting the availability of actual flight test 
data; and then comparing this new data with 
the newly available flight test data. The re-
sults of such comparisons have, as reported 
by some recognized and experienced simula-
tion experts, become increasingly consistent 
and indicate that these techniques, applied 
with appropriate experience, are becoming 
dependably accurate for the development of 
aerodynamic models for use in Level 6 FTDs. 

c. In reviewing this history, the NSPM has 

concluded that, with proper care, those who 
are experienced in the development of aero-
dynamic models for FTD application can 
successfully use these modeling techniques 
to acceptably alter the method by which 
flight test data may be acquired and, when 
applied to Level 6 FTDs, does not com-
promise the quality of that simulation. 

d. The information in the table that fol-

lows (Table of Alternative Data Sources, 
Procedures, and Information: Level 6 FTD 
Only) is presented to describe an acceptable 
alternative to data sources for Level 6 FTD 
modeling and validation, and an acceptable 
alternative to the procedures and instrumen-
tation found in the flight test methods tradi-
tionally accepted for gathering 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 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).
