Pt. 60, App. A 

e. In those cases where the objective test 

results authorize a ‘‘snapshot test’’ or a ‘‘se-
ries of snapshot tests’’ results in lieu of a 
time-history result, the sponsor or other 
data provider must ensure that a steady 
state condition exists at the instant of time 
captured by the ‘‘snapshot.’’ The steady 
state condition must exist from 4 seconds 
prior to, through 1 second following, the in-
stant of time captured by the snapshot.

f. The FFS sponsor is encouraged to main-

tain a liaison with the manufacturer of the 
aircraft being simulated (or with the holder 
of the aircraft type certificate for the air-
craft being simulated if the manufacturer is 
no longer in business), and, if appropriate, 
with the person having supplied the aircraft 
data package for the FFS in order to facili-
tate the notification required by § 60.13(f). 

g. It is the intent of the NSPM that for 

new aircraft entering service, at a point well 
in advance of preparation of the Qualifica-
tion Test Guide (QTG), the sponsor should 
submit to the NSPM for approval, a descrip-
tive document (see Table A2C, Sample Vali-
dation Data Roadmap for Airplanes) con-
taining the plan for acquiring the validation 
data, including data sources. This document 
should clearly identify sources of data for all 
required tests, a description of the validity 
of these data for a specific engine type and 
thrust rating configuration, and the revision 
levels of all avionics affecting the perform-
ance or flying qualities of the aircraft. Addi-
tionally, this document should provide other 
information, such as the rationale or expla-
nation for cases where data or data param-
eters are missing, instances where engineer-
ing simulation data are used or where flight 
test methods require further explanations. It 
should also provide a brief narrative describ-
ing the cause and effect of any deviation 
from data requirements. The aircraft manu-
facturer may provide this document. 

h. There is no requirement for any flight 

test data supplier to submit a flight test 
plan or program prior to gathering flight 
test data. However, the NSPM notes that in-
experienced data gatherers often provide 
data that is irrelevant, improperly marked, 
or lacking adequate justification for selec-
tion. Other problems include inadequate in-
formation regarding initial conditions or 
test maneuvers. The NSPM has been forced 
to refuse these data submissions as valida-
tion data for an FFS evaluation. It is for this 
reason that the NSPM recommends that any 
data supplier not previously experienced in 
this area review the data necessary for pro-
gramming and for validating the perform-
ance of the FFS, and discuss the flight test 

plan anticipated for acquiring such data with 
the NSPM well in advance of commencing 
the flight tests. 

i. The NSPM will consider, on a case-by- 

case basis, whether to approve supplemental 
validation data derived from flight data re-
cording systems, such as a Quick Access Re-
corder or Flight Data Recorder.

a. In the event that the NSPM determines 

that special equipment or specifically quali-
fied persons will be required to conduct an 
evaluation, the NSPM will make every at-
tempt to notify the sponsor at least one (1) 
week, but in no case less than 72 hours, in 
advance of the evaluation. Examples of spe-
cial equipment include spot photometers, 
flight control measurement devices, and 
sound analyzers. Examples of specially quali-
fied personnel include individuals specifi-
cally qualified to install or use any special 
equipment when its use is required. 

b. Examples of a special evaluation include 

an evaluation conducted after an FFS is 
moved, at the request of the TPAA, or as a 
result of comments received from users of 
the FFS that raise questions about the con-
tinued qualification or use of the FFS.
