CHAPTER ELEVEN
constant, but the aft stick force required to obtain this will vary with airspeed and "G" loading.
Directional control is maintained by adjusting rudder input as the airspeed varies, thereby
maintaining balanced flight. Aileron is used only in making corrections to maintain the wings
parallel with the horizon throughout the entire maneuver.
When the Loop is performed correctly, positive "G" loading and constant nose pitch movement
should be maintained throughout the maneuver. As airspeed varies, the resulting transcribed arc
will also vary in radius, therefore backstick pressure will vary in order to maintain constant nose
pitch movement. The result will produce a Loop that has an egg-shaped appearance when
viewed on the horizon. Remember to select a long, well defined section line which extends
behind as well as in front of you.

Procedures
a.
CONFIGURATION: Transition to aerobatic cruise. CHECKLIST: Complete the
aerobatic checklist. CLEARING TURN: Commence a clearing turn. During the
last 90 of turn, lower the nose slightly and accelerate to 200 KIAS. Roll out of the
clearing turn on or parallel to a section line with 200 KIAS. The increased airspeed
will require a slight amount of left rudder to maintain balanced flight.
b.
Recheck the wings level and clear the airspace above you. Just prior to entry, check
and report the entry altitude over the ICS. Commence the AGSM and immediately
start a smooth straight pull up accelerating to 3.5 Gs within two to three seconds. Do
not use the aileron.
c.
Recheck the wings level as the nose passes through the horizon. Adjust stick pressure
as necessary to keep the nose moving at a constant rate. Increase right rudder
pressure as airspeed decreases.
d.
Shortly after passing the vertical position, tilt your head back and visually locate the
opposite horizon. Correct with aileron as necessary to maintain the wings parallel to
the horizon. Check the nose in relation to the section line and correct directional
deviations as necessary by adjusting the rudder input.
e.
Airspeed will reach its slowest point at the top of the Loop. The greatest amount of
right rudder input will therefore be required at this point in order to maintain balanced
flight. The amount of aft stick force required to maintain a constant nose pitch rate
will have decreased significantly from the initial pull-up. Maintain positive "G"
loading and wings parallel to the horizon.
f.
Allow the nose to fall through the opposite horizon, adjusting the amount of aft stick
pressure to maintain a constant pitch rate. Fly the aircraft's nose along the section
line, relaxing right rudder pressure as airspeed is quickly regained.
g.
Continue to relax right rudder pressure as the airspeed increases in the dive and
smoothly increase aft stick pressure as necessary to maintain a constant pitch rate.
The recovery will again require approximately 3.5 Gs, so remember to resume the
