Student solos are strictly prohibited from performing the Split-S,
Immelmann Combination Maneuver, and intentional sustained
inverted flight maneuvers. Failure to comply with this safety
related restriction is considered sufficient grounds for attrition
from flight training.
2. General. The Split-S provides a means of rapidly converting the potential energy of
altitude into airspeed while reversing the direction of flight. Once the pull is commenced from
the inverted position, airspeed builds rapidly and altitude is quickly lost. If performed correctly,
the altitude loss should be approximately 1500 feet. Remember to select a long, well defined
section line which extends behind as well as in front of you.
CONFIGURATION: Transition to aerobatic cruise. CHECKLIST: Complete the
Aerobatic Checklist. CLEARING TURN: Commence a clearing turn. After rolling
out of the clearing turn, reduce power to idle and maintain altitude while slowing to
130 KIAS. Increase right rudder pressure as the aircraft decelerates in order to
maintain balanced flight.
Raise the nose to place the exhaust stacks on the horizon, relax the backstick pressure
and roll in either direction using aileron and rudder to the inverted position.
Once inverted, neutralize the ailerons and apply slight forward stick pressure to
momentarily maintain straight and level flight. Quickly verify that the wings are
level by referencing the horizon and correct as necessary. Apply back stick pressure,
pulling the nose through the horizon and flying the aircraft along the section line as in
the last half of the Loop. Decrease right rudder pressure as the aircraft accelerates to
Check oil pressure within normal limits. Reset aerobatic cruise power and report the
oil pressure over the ICS.
Failure to maintain altitude and/or balanced flight during the deceleration.
Delaying roll initiation, airspeed decay causes difficult lateral control.
Failure to obtain, check and/or correct wings level prior to the pull-out. This results
in disorientation and a rolling pull-out.
Pulling too much backstick before sufficient airspeed has been gained resulting in a
