Federal Aviation Administration, DOT 

Pt. 60, App. C 

support qualification of the FFS at the level 
requested. 

d. As required by § 60.13(f), the sponsor 

must notify the NSPM when it becomes 
aware that an addition to, an amendment to, 
or a revision of data that may relate to FFS 
performance or handling characteristics is 
available. The data referred to in this para-
graph is data used to validate the perform-
ance, handling qualities, or other character-
istics of the aircraft, including data related 
to any relevant changes occurring after the 
type certificate was issued. The sponsor 
must— 

(1) Within 10 calendar days, notify the 

NSPM of the existence of this data; and 

(2) Within 45 calendar days, notify the 

NSPM of— 

(a) The schedule to incorporate this data 

into the FFS; or 

(b) The reason for not incorporating this 

data into the FFS. 

e. In those cases where the objective test 

results authorize a ‘‘snapshot test’’ or a ‘‘se-
ries of snapshot test 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 snap shot.

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 who 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 QTG, the 
sponsor should submit to the NSPM for ap-
proval, a descriptive document (see Table 
C2D, Sample Validation Data Roadmap for 
Helicopters) containing the plan for acquir-
ing the validation data, including data 
sources. This document should clearly iden-
tify sources of data for all required tests, a 
description of the validity of these data for a 
specific engine type and thrust rating con-
figuration, and the revision levels of all avi-
onics affecting the performance or flying 
qualities of the aircraft. Additionally, this 
document should provide other information, 
such as the rationale or explanation for 
cases where data or data parameters are 
missing, instances where engineering sim-
ulation 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.
