Rate Of Climb - AUTO GYRO Rotax 916 IS Pilot Operating Handbook

The following speeds are relevant for controllability. Safe operational speeds and limitations
are provided in SECTION 2 Limitations of this manual.

* Take care! A full power operation at Vmin with a Rotax 915iS or 916iS engine
will result in a very high nose-up attitude with little forward visibility, and very
little airspeed. Airspeed indication below 25km/h (20mph, 15KIAS) is unreliable.
Further, rotor rpm will be reduced due to the aircraft being partially supported
ROTOR RPM MUST BE MAINTAINED ABOVE 280!
Take great care, especially when flying at light weight, to maintain rotor rpm.
** Long range speed is the speed faster than the best range speed which
results in a slightly lesser range but represents a good compromise between
range and saved air time.
*** Approach speed above 100kmh (60mph, 50KIAS) builds energy in the
rotor that results in a long floating landing. Approach speed at 80kmh
(50mph, 40KIAS) results in a very short landing roll, and below 80kmh
requires increasing skill especially at max TOW.
****V is the minimum controllability speed. At 30kmh (20mph, 15KIAS) or
mc
below, engine off, rudder authority reduces, to negligible below 15kmh
(10mph, 8KIAS).
TOP is Take-Off Power.
