4-18 ENSTROM 280FX OPERATOR’S MANUAL
FAA Approved: Jul 27/15 Rev. 10
Report No. 28-AC-020 Apr 15/15
NOTE
This helicopter is equipped with a mechanical
throttle correlation device. The correlator will
compensate for changes in collective pitch when
manifold pressure is above 25 inches Hg and will
maintain RPM within the normal operating range
for normal hover maneuvering.
NOTE
Hovering IGE above 10,000 ft density altitude is
limited to 5 minutes.
CAUTION
Avoid maneuvers that require full pedal travel or
rapid pedal reversals.
4-13. Normal Takeoff
1. Align helicopter with desired takeoff course at a
stabilized hover height of approximately 2 ft.
2. Check power required to hover.
3. Smoothly apply forward cyclic to begin acceleration into
effective translational lift.
4. As the helicopter begins forward movement, maintain
altitude by increasing collective pitch.
NOTE
Adjust acceleration rate so approximately 1-2
inches of manifold pressure over hover power is
required. Maintain 2 ft hover altitude or lower
altitude if permitted by safe obstacle or terrain
clearance.
NOTE
During smooth transition into a climb from a
hover, there is a tendency for the RPM to climb
and exceed the red line. The pilot should
