1003. AEROBATIC CHECKLIST
Prior to performing any aerobatic maneuver or series of the same maneuver, complete the
Aerobatic Checklist. This will assure you that your aircraft is prepared for aerobatic flight. The
checklist is as follows:
Bilges - "Clear of loose objects, control lock stowed (in two places)"
Restraint harness - "Locked and tight."
Autoignition - "On, AUTO IGN light, ON."
Engine instruments - "Checked" (for normal indications).
Report - "Aerobatic Checklist complete."
Ensure that all loose items (checklists, charts, pubs, clips, water bottles, etc.) are secure in either
the map case or a zipped pocket. Your inertial reel should be locked and the harness tight (waist
and shoulder straps). The control lock should be visually checked to ensure that it is secured in
both places. Check that the autoignition light actually illuminates and make a mental note to
secure it once all aerobatic maneuvers and/or stalls are complete. Take the time to check each
instrument for normal indications. Additionally adjust the friction knob so that sufficient
pressure is applied to prevent the PCL from slipping during high G maneuvers. Taking the time
and effort to do your Aerobatic Checklist correctly can prevent some unwelcome surprises.
1004. SECTION LINES AND GROUND REFERENCE POINTS
The maneuver descriptions and procedures of the various aerobatic maneuvers often refer to
section lines and ground reference points. Understanding how to select and utilize these
geographical references will greatly enhance your ability to remain oriented during the various
Much of the area you will fly over is rural farm land (Whiting) or beachline/waterways (Corpus
Christi). The lines which separate one "section" of land from another is called a "section line."
These lines commonly run north/south or east/west in long, straight lines and are easily identified
from the air. During the various maneuvers, these section lines are utilized as a reference to
maintain directional control. Since some maneuvers involve a reversal in the direction of flight,
it becomes necessary to select a line which extends both in front of and behind you. Highways,
utility cuts or even beachlines may also be utilized, provided they are linear and of sufficient
Maneuvers such as the Barrel Roll or Wingover require the use of a ground reference point
which is 90º from your initial heading. Ensure that the points which you select are prominent
and easily seen, remembering that you will have to relocate them rapidly as you are passing
through unusual attitudes. The rate at which you must scan while performing the maneuvers
does not allow the time to search for a hard-to-see reference point.
