VINTAGE AEROBATIC WORLD CHAMPIONSHIP 2017
HOW TO BECOME A TRUE WORLD CHAMPION….
By: Lars Görean Arvidsson, Chief Judge
First of all let me state that I am honoured to be asked to head the judging line of the second Vintage Aerobatic World Championship..
I am really looking forward to seeing the most beautiful manoeuvres flown in the romantic historic airplanes, elegantly handled by their brave and talented pilots!
In my many (MANY) years I have been involved in the aerobatic sport – judging some of the best pilots in the world – I have only seen 2 perfect loops. Loops worthy of the rare score 10. Loops which is entered and finished in the exact same altitude, which is absolutely circular round, which have a steady pitch rate all the way round and flown absolutely parallel to the judging line. Wow. Let me se that from you! But remember that you have to compensate from the wind-factor… so the loop looks perfect from my point of view!
Do not be too worried, as I said…nobody can do a perfect loop. (I challenge you!!! ϑ). Expanding the one manoeuvre to a full program of manoeuvres: Here the positioning in front of the judges is crucial. Lines across the “competition box” (edged by a line parallel to the judging line) needs to be 90dg to the judging line. Every manoeuvre must be separated by a short (or long) horizontal line. All programs must be initiated and finished with three clearly visible wing-dip. Just to wake up the judging line.. and to put us a sleep again. Please remember this. It will give the impression that you are ready and in control…
Zooming in on the different manoeuvres, and building on above, this is what I will be looking for… to give you the rare score of 10 …
As described above
Pitch and roll in harmony. Wings vertical at the top. Pitch rate constant before/after the top.
Pitch and roll in harmony. Wings vertical at the top. Wings level (inverted) at horizon, Wings vertical at the bottom. Start and end-heading the same and parallel to the judging line.
Quarter roll up each segment and within the four segment. 90dg turn pr. segment. Pitch and roll in harmony. Start and finish at same heading, parallel to the judging line.
Looping-segments round. Looping segments in 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
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. On line with presentation aksis of course.
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 with in the roll segments. Same roll rate in all segments. On the line.
Constant roll rate. Horizontal line..(or as close you can get)(Engine coughing allowed)
Scoring principles for the competition flights:
Aresti scoring system, manoeuvres 70%
Positioning in front of the judges 10%
Rhythm and showmanship 10%
Safety attitude 10% (however possible abandoning if flying is UNSAFE)
- Zero penalty for breaking for height, re-climb and restart. However, you will of cause loose point in the “rhythm and positioning score”.
- Manoeuvres flown behind the judging line is zeroed.
Scoring principle for THE PERFORMANCE:
All attending pilots and judges will be the judges. Two scores each: FLYING QUALTY and PERFORMANCE IMPACT. Sings (1-10) will be raised just after each flight. The PERFORMANCE will be assisted by show-speech and music (if participant prefers).
To make VAWC a safe event following higth limitations (AGL) will be applied: Looping the Loop: 1500 feet. Dancing the CloverLeaf: 1000 feet. Rolling the circle: 500 feet. 10% penalty in total points for flying 100 feet below low limit. Below this, your flight will be “zeroed”. Stay safe, stay high!
Number of flights
We aim to have each pilot fly 2 flights (+ The Performance). If weather is against us the World Champions can be announced after only one flight (all pilots).
