Judging criteria – what we will be looking for. In general, we will be looking for a flight with rhythm, harmony, precision and elegance; well centered in front of the judges and flown parallel to the box lines (X- and Y-axis)
Following maneuvers are allowed before the wing-dip: Humpty bump or Hammerhead… and if desired in combination with a 2-point roll.
Wing-dip before the start of your program
All programs must be initiated and finished with three clearly visible wing-dip. The wing-dips can be inside the box, it can be on the speed dive-line allowing you NOT to loose energy after having reached you desired starting altitude. (Remember to signal interruption of program with 3 wing dip as well!)
Radio control, Judging line and tower
Except if the Contest Director allows otherwise, all participants must have a functional VHF radio and keep up communication readiness with either the “tower” or Chief Judge. More instructions on procedures at the competition
What the judges will be looking for in the maneuvers
First and last: It is imperative that every maneuver must be separated by a short (or long) horizontal line.
Following criteria is in particular aimed to the participants NOT familiar with aerobatic competition.
Loop: Vertical circular flight path starting and ending in same height.
Wing over: Pitch and roll in harmony. Wings vertical at the top. Pitch rate constant before/after the top.
Barrel roll: Pitch and roll in harmony flying a horizontal “barrel”. Start and end-heading the same and parallel to the judging line. (When performed on X-Axis)
Cloverleaf: Quarter roll UP – or down – (as per instruction in the annual program) in each segment and within the four segments. 90dg turn pr. segment. Pitch and roll in harmony. Start and finish at same heading, parallel to the judging line.
Cuban eight: Looping-segments round. Looping segments with same radius. Half-rolls positioned at mid-line down. Half rolls on course and with constant roll rate. Half rolls stopped after precisely 180 dg.
180 dg horizontal turn: From level and horizontal flight roll briskly to 60-degree bank maintain 60- degree and turn 180 degree roll briskly to level and horizontal flight
Top roll: Circular looping segment. Half roll positioned and … adjusted with roll rate… so you will end up flying horizontal straight and level just after the top of the loop. Heading during the roll and after the roll, on axis.
4-point roll: Horizontal line (or as close you can get). Four segments of the roll: 1) 90dg, 2) 180 dg, 3) 270 dg, 4) 360 dg. Same roll rate within the roll segments. Same roll rate in all segments. On the line.
Roll: Constant roll rate. Horizontal line. (…or as close you can get) (Engine coughing allowed)
