Pt. 60, App. C 

the simulator sponsor can provide an ade-
quate explanation. 

(6) Guidelines are needed for the applica-

tion of tolerances to engineering-simulator- 
generated validation data because: 

(a) Flight-test data are often not available 

due to sound technical reasons; 

(b) Alternative technical solutions are 

being advanced; and 

(c) The costs are high.

a. Helicopter manufacturers or other data 

suppliers should supply a validation data 
roadmap (VDR) document as part of the data 
package. A VDR document contains guid-
ance material from the helicopter validation 
data supplier recommending the best pos-
sible sources of data to be used as validation 
data in the QTG. A VDR is of special value 
when requesting interim qualification, quali-
fication of simulators for helicopters certifi-
cated prior to 1992, and qualification of alter-
nate engine or avionics fits. A sponsor seek-
ing to have a device qualified in accordance 
with the standards contained in this QPS ap-
pendix should submit a VDR to the NSPM as 
early as possible in the planning stages. The 
NSPM is the final authority to approve the 
data to be used as validation material for the 
QTG. The NSPM and the Joint Aviation Au-
thorities’ Synthetic Training Devices Advi-
sory Board have committed to maintain a 
list of agreed VDRs. 

b. The VDR should identify (in matrix for-

mat) sources of data for all required tests. It 
should also provide guidance regarding the 

validity of these data for a specific engine 
type, thrust rating configuration, and the re-
vision levels of all avionics affecting heli-
copter handling qualities and performance. 
The VDR should include rationale or expla-
nation in cases where data or parameters are 
missing, engineering simulation data are to 
be used, flight test methods require expla-
nation, or where there is any deviation from 
data requirements. Additionally, the docu-
ment should refer to other appropriate 
sources of validation data (e.g., sound and vi-
bration data documents). 

c. The Sample Validation Data Roadmap 

(VDR) for helicopters, shown in Table C2D, 
depicts a generic roadmap matrix identifying 
sources of validation data for an abbreviated 
list of tests. This sample document uses 
fixed wing parameters instead of helicopter 
values. It is merely a sample and does not 
provide actual data. A complete matrix 
should address all test conditions for heli-
copter application and provide actual data 
and data sources. 

d. Two examples of rationale pages are pre-

sented in Appendix F of IATA Flight Simu-
lator Design and Performance Data Require-
ments document. These illustrate the type of 
helicopter and avionics configuration infor-
mation and descriptive engineering rationale 
used to describe data anomalies or provide 
an acceptable basis for using alternative 
data for QTG validation requirements.
