DATA CRITERIA
5-3 DATA BASIS
The type of data used is indicated at the bottom of each performance
chart under DATA BASIS. The applicable report and date of the data
are also given. The data provided generally are based on one of
three categories:
a.
Derived From Actual Controlled Testing.
Controlled test data
obtained on a similar unit type.
b.
Calculated Data.
Data based on tests, but not on a similar
unit type placed under a controlled test.
c.
Estimated Data
. Data based on estimates using rules of phys-
ics, mathematics, and electrical engineering principles and con-
cepts, but not verified by tests.
5-4. SPECIFIC CONDITIONS
The data presented are accurate only for specific conditions listed
under the title of each chart or graph. Variables for which data are
not presented, but which may affect that phase of performance, are
discussed in associated text. Where data are available or reasonable
estimates can be made, the amount that each variable affects perfor-
mance will be given.
5-5. GENERAL CONDITIONS
In addition to the specific conditions, the following general condi-
tions are applicable to the performance data.
a.
Variation in Aircraft.
Power demand differences between indi-
vidual aircraft of the same make and model are known to exist due
to variations in DC electrical system efficiency. These differ-
ences, however, are considered insignificant and are not individu-
ally accounted for.
b.
Ground Support and Aircraft Instrument Variations.
