CONFIGURATION: Transition to aerobatic cruise. CHECKLIST: Complete the
Aerobatic Checklist. CLEARING TURN: Commence a clearing turn. During the
last 90º 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.
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.
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.
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.
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.
Allow the nose to fall through the opposite horizon, adjusting the amount of aft stick
pressure to maintain a constant pitch rate. As the nose approaches a point 30º below
the opposite horizon, slow the nose movement by releasing backstick pressure and
commence a roll in either direction, using aileron and rudder. During the roll, it will
take slight forward stick pressure as the aircraft passes wings vertical to hold the
heading and allow the nose to continue pitching downward to a position 45º below
Commence a smooth pullout to straight and level balanced flight 600-700 feet prior to
the original entry altitude. Recover on the original altitude and reciprocal heading.
Same common errors as the first half of a Loop.
Improper forward stick application during roll resulting in less than the desired 45º
nose down attitude.
Failure to initiate the pull-out 600-700 feet prior.
