1005. CLEARING TURNS

During aerobatic flight, attitude, altitude and direction of flight change rapidly. You must

therefore exercise extreme caution by ensuring the immediate area is clear of other aircraft and

that no danger of midair collision exists. A clearing turn, as the name implies, allows you to

clear the area in which you are operating. A clearing turn shall be executed after the Aerobatic

Checklist and immediately prior to the performance of any aerobatic maneuver. Utilize a

minimum of 45 angle of bank and turn for a minimum of 180 of heading change. Two 90

turns in opposite directions will suffice. The direction of the last clearing turn shall be in the

direction in which the maneuver will be performed. Throughout the turn, check the area

thoroughly for other aircraft. Continue the turn until you have the desired airspeed and sufficient

ground references to maintain orientation during the maneuver. Remember 180 of turn is a

minimum, not an absolute.

If the number of section lines or ground references is limited, then a teardrop maneuver is an

effective means of performing the clearing turn while positioning the aircraft for the next

maneuver. This may be performed by turning to place the nose approximately 45 from the

section line, timing for 10-15 seconds, and then turning back to the reciprocal of the original

heading.

Common Errors

Failure to plan or execute the clearing turn(s) so that the chosen ground references are

properly positioned to allow for adequate orientation during the subsequent

maneuver.

Not "clearing" the area sufficiently during the turn.

Poor basic airwork during the clearing turn(s), resulting in the aircraft not being at the

correct altitude and/or airspeed to commence the planned maneuver in a timely

fashion.

Failure to execute the maneuver within the cleared airspace.

1006. ALTITUDE LIMITATIONS

Commence each aerobatic maneuver from an altitude which is sufficient to allow a return to

straight and level flight above 5000 feet AGL. You must also exercise caution to ensure that you

do not exceed the maximum altitude permitted for your particular operating area. If performed

correctly, all of the maneuvers (except the Aileron Roll) require approximately 1500 feet of

vertical airspace. Use this figure while planning your entry altitude, keeping in mind that the

minimum recommended altitude for bailout during out-of-control flight is also 5000 feet AGL.

Sound judgment applies in choosing an altitude from which to commence each particular

maneuver. Generally, the higher you can begin without exceeding your maximum altitude is the

most logical choice. As your experience increases, you should manage your altitudes in order to

control your energy states more effectively, thus increasing efficiency within the same allotted

time and available fuel.
