3.8.3
(Cont)
to show variation of power required with rpm. One of the
rpm's chosen shall be rpm for normal rated power (NRP). At
the rpm for NRP, power required in level flight through-
out the speed range shall be determined at sea level for
an overload weight if practicable, and a reduced
weight chosen so as to show variation of power
required with gross weight. Normal take-off weight
plus and minUS 10 percent is suggested.
(2) Maximum forward speed at normal take-off
weight
with NRP.
Power required to hover at sea level at three differ-
(3)
ent rpm's and three weights as called for under (1)
above.
(4)
At normal take-off weight and rpm for NRP required
in level flight throughout the practicable speed
range shall be determined at 5000 foot increments
in altitude up to service ceiling.
Hovering ceiling at normal take-off weight with NRP
(5)
and with take-off power.
All performance demonstration items shall be performed out of ground
effect. In connection with determination of performance, observation
shall also be made regarding compliance with pertinent flying qualities
design requirements which are not specifically required for demnstra-
tion under Table 3. Unless otherwise specified, all performance data
shall be reduced to standard NASA atmospheric conditions.
