45.1 General
FAR 25.21 : Proof of compliance.
(a)
Each requirement of this subpart must be met at each appropriate combination of weight and center of gravity within the range of loading conditions for which certi.cation is requested. This must be shown–
(1)
By tests upon an airplane of the type for which certi.cation is requested, or by calculationsbased on, and equalin accuracy to,the results of testing; and
(2)
By systematicinvestigation of eachprobable combination of weight and center of gravity, if compliance cannot be reasonably inferred from combinations investigated.
(b)
[[Reserved.]]
(c)
The controllability, stability, trim, and stalling characteristics of the airplane must be shown for each altitude up to the maximum expected in operation.
(d)
[Parameters critical for the test being conducted, such as weight, loading (center of gravity and inertia), airspeed, power, and wind, must be maintained within acceptable tolerances of the critical values during .ight testing.]
(e)
If compliancewith the .ightcharacteristicsrequirementsisdependentuponastabi-lity augmentation system or upon any other automatic orpower-operated system, compliance must be shown with Secs. 25.671 and 25.672.
(f)
In meeting the requirementsofSecs.25.105(d),25.125,25.233,and25.237,the wind velocity must be measured at a height of 10 meters above the surface, or corrected for the di.erence between the height at which the wind velocity is measured and the 10-meter height.
