EQUIREMENTS

a. Flight test data used to validate FTD

performance and handling qualities must
have been gathered in accordance with a
flight test program containing the following:

(1) A flight test plan consisting of:
(a) The maneuvers and procedures required

for aircraft certification and simulation pro-
gramming and validation.

(b) For each maneuver or procedure—
(i) The procedures and control input the

flight test pilot and/or engineer used.

(ii) The atmospheric and environmental

conditions.

(iii) The initial flight conditions.
(iv) The airplane configuration, including

weight and center of gravity.

(v) The data to be gathered.
(vi) All other information necessary to

recreate the flight test conditions in the
FTD.

(2) Appropriately qualified flight test per-

sonnel.

(3) An understanding of the accuracy of the

data to be gathered using appropriate alter-
native data sources, procedures, and instru-
mentation that is traceable to a recognized
standard as described in Attachment 2, Table
B2F of this appendix.

(4) Appropriate and sufficient data acquisi-

tion equipment or system(s), including ap-
propriate data reduction and analysis meth-
ods and techniques, acceptable to the FAA’s
Aircraft Certification Service.

b. The data, regardless of source, must be

presented:

(1) In a format that supports the FTD vali-

dation process;

(2) In a manner that is clearly readable and

annotated correctly and completely;

(3) With resolution sufficient to determine

compliance with the tolerances set forth in
Attachment 2, Table B2A, Appendix B;

(4) With any necessary guidance informa-

tion provided; and

(5) Without alteration, adjustments, or

bias. Data may be corrected to address
known data calibration errors provided that
an explanation of the methods used to cor-
rect the errors appears in the QTG. The cor-
rected data may be re-scaled, digitized, or
otherwise manipulated to fit the desired
presentation.

c. After completion of any additional flight

test, a flight test report must be submitted
in support of the validation data. The report
must contain sufficient data and rationale to
support qualification of the FTD 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 or a revision of the

flight related data or airplane systems re-
lated data is available if this data is used to
program and operate a qualified FTD. The
data referred to in this sub-section are those
data that are 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 certification is 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—

(i) The schedule to incorporate this data

into the FTD; or

(ii) The reason for not incorporating this

data into the FTD.

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.

NFORMATION

f. The FTD 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 FTD in order to facili-
tate the notification described in this para-
graph.

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 Appendix
A, Table A2C, Sample Validation Data Road-
map for Airplanes) containing the plan for
acquiring 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
