history and valid outcomes. This must in-
clude comparisons of predicted and flight 
test validated data. 

b. Airplane manufacturers or other accept-

able data suppliers seeking to use an engi-
neering simulator for simulation validation 
data as an alternative to flight-test derived 
validation data, must contact the NSPM and 
provide the following: 

(1) A description of the proposed aircraft 

changes, a description of the proposed sim-
ulation model changes, and the use of an in-
tegral configuration management process, 
including a description of the actual simula-
tion model modifications that includes a 
step-by-step description leading from the 
original model(s) to the current model(s). 

(2) A schedule for review by the NSPM of 

the proposed plan and the subsequent valida-
tion data to establish acceptability of the 
proposal. 

(3) Validation data from an audited engi-

neering simulator/simulation to supplement 
specific segments of the flight test data. 

c. To be qualified to supply engineering 

simulator validation data, for aerodynamic, 
engine, flight control, or ground handling 
models, an airplane manufacturer or other 
acceptable data supplier must: 

(1) Be able to verify their ability able to: 
(a) Develop and implement high fidelity 

simulation models; and 

(b) Predict the handling and performance 

characteristics of an airplane with sufficient 
accuracy to avoid additional flight test ac-
tivities for those handling and performance 
characteristics. 

(2) Have an engineering simulator that: 
(a) Is a physical entity, complete with a 

flight deck representative of the simulated 
class of airplane; 

(b) Has controls sufficient for manual 

flight; 

(c) Has models that run in an integrated 

manner; 

(d) Has fully flight-test validated simula-

tion models as the original or baseline sim-
ulation models; 

(e) Has an out-of-the-flight deck visual sys-

tem; 

(f) Has actual avionics boxes interchange-

able with the equivalent software simula-
tions to support validation of released soft-
ware; 

(g) Uses the same models as released to the 

training community (which are also used to 
produce stand-alone proof-of-match and 
checkout documents); 

(h) Is used to support airplane development 

and certification; and 

(i) Has been found to be a high fidelity rep-

resentation of the airplane by the manufac-
turer’s pilots (or other acceptable data sup-
plier), certificate holders, and the NSPM. 

(3) Use the engineering simulator/simula-

tion to produce a representative set of inte-
grated proof-of-match cases. 

(4) Use a configuration control system cov-

ering hardware and software for the oper-
ating components of the engineering simu-
lator/simulation. 

(5) Demonstrate that the predicted effects 

of the change(s) are within the provisions of 
sub-paragraph ‘‘a’’ of this section, and con-
firm that additional flight test data are not 
required. 

d. Additional Requirements for Validation 

Data 

(1) When used to provide validation data, 

an engineering simulator must meet the sim-
ulator standards currently applicable to 
training simulators except for the data pack-
age. 

(2) The data package used must be: 
(a) Comprised of the engineering pre-

dictions derived from the airplane design, de-
velopment, or certification process; 

(b) Based on acceptable aeronautical prin-

ciples with proven success history and valid 
outcomes for aerodynamics, engine oper-
ations, avionics operations, flight control ap-
plications, or ground handling; 

(c) Verified with existing flight-test data; 

and 

(d) Applicable to the configuration of a 

production airplane, as opposed to a flight- 
test airplane. 

(3) Where engineering simulator data are 

used as part of a QTG, an essential match 
must exist between the training simulator 
and the validation data. 

(4) Training flight simulator(s) using these 

baseline and modified simulation models 
must be qualified to at least internationally 
recognized standards, such as contained in 
the ICAO Document 9625, the ‘‘Manual of Cri-
teria for the Qualification of Flight Simula-
tors.’’

NFORMATION

 

a. Non-Flight-Test Tolerances 
(1) If engineering simulator data or other 

non-flight-test data are used as an allowable 
form of reference validation data for the ob-
jective tests listed in Table A2A of this at-
tachment, the data provider must supply a 
well-documented mathematical model and 
testing procedure that enables a replication 
of the engineering simulation results within 
40% of the corresponding flight test toler-
ances. 

b. Background 
(1) The tolerances listed in Table A2A of 

this attachment are designed to measure the
