2006 WINTER JUDGES PILOTS CLINIC
3
WHERE DO WE GO WRONG?
4
Some pilots think judges do a poor job. True or
false?
5
False!
All judges try to deliver their best some are
just more experienced than others
6
Some judges think fliers do a poor job. True or
false?
7
False!
All fliers try to deliver their best some are
just more experienced than others
8
Hopefully this forum will bridge the gap between
judges and fliers. In the far-off days of
acrobatic flying, the judges were almost
untouchable. Slowly this changed to the present
where judges became accessible to all fliers.
9
But, with this détente came a new problem fliers
were openly attacking certain judges and their
opinions. This is partly as a result of
ignorance, the fliers not realising exactly where
they are losing points.
10
Principles of Judging
11
Good Judging Qualities

• Consistency establish standard maintain
• Accurancy fair reflection. Use downgrades for
  specific defects
• Close agreement on a par with fellow judges
• Impartiality totally neutral and unbiased, no
  matter who flies
• Objectivity try and forget personal opinions

12
Criteria
Each manoeuver is downgraded according to

• Type of defect
• Severity of defect
• Number of times any defect occurs
• Size of manoeuver relative to others

GIVE TOP SCORE ONLY IF NO DEFECTS OBSERVED!
13
Attitude

• Attitude direction of fuselage in relation to
  flight path
• Flight Path trajectory of centre of gravity
• All manoeuvers wind corrected for flight path
  to bo geometrically OK

ALL JUDGING BASED ON FLIGHT PATH
14
Marking

• Each manoeuver scored between 10 and 0
  (inclusive)
• Centre manoeuveres in centre of box
• Turnaround manoeuveres not past 60º marks
• All maoeuveres done on parallel line, 150m
  from pilot
• Infractions downgraded proportionally to
  degree of being out

15
1-Point / 15º Rule

• General guide for downgrading deviations from
  defined geometry
• One point subtracted for each 15º deviation
• So, 45º off (1/8) is a 3 point downgrade, and
  90º (1/4) is minus 6!
• Up to 15º off heading is 1 point downgrade
• Up to 15º off vertical is 1 point downgrade

16
LINES

• All manoeuveres start finish with horizontal
  lines
• Total length of line not graded. Only where
  given relationship exist, like square loop, etc
• Minor misrelation 1 point downgrade. More
  for greater defects
• No line flown between to manoeuveres

2 POINT DOWNGRADE!

17

LINES

• Must be perfectly horizontal, vertical or
  angled as required
• With any type of roll, lines before after
  roll must be equal
• One point downgrade for minor misrelation.
  More for greater defects
• Complete absense of line before or after roll

2 POINT DOWNGRADE!

18
LOOPS

• Constant radius
• Vertical plane
• Well-defined entry / exits
• Part-loops all same radii
• Slight difference 1 point downgrade. Severe
  minus 2 or 3 points
• No segmentation to circular flight path. Every
  seen segmentation minus 1
• Minor drift minus 1 point. Severe drift
  more points downgrade

19
ROLLS

• Roll rate constant. Small variation minus 1
  point. More severe heavier downgrades
• Crisp well-defined start and stop. Bad
  definition minus 1 point
• Point rolls must have equal time for each
  point
• Missing or extra point

5 MORE DOWNGRADED!
20
STALL TURNS

• Mainly about lines
• Entry exit part-loops must have equal radii
• Maximum pivot without downgrade is ½ span
• More than 11/2 span, severely downgraded
• Pendulum after stall minus 1 point
• Skid (low wing) before stall minus 1 point
• Torque-off apply 1-pt/15º rule

21
SNAP ROLLS

• Rapid autorotative roll, in stalled attitude
  (spin, but in forward flight)
• Definite break in attitude and flight path
  before rotation
• Barrel roll ZERO!
• No snap ZERO!
• Positive when negative required ZERO! (or
  vice-versa)
• Over or undersnap use 1-pt/15º rule

22
SPINS

• Begin end horizontally
• Must be stalled
• Nose/wing drops, not lift
• Near-vertical downline projected after spin
• No stall ZERO POINTS!
• Snap entry ZERO!
• Spiral dive ZERO!
• Over or underspin use 1pt/15º rule NOTE-
  45º off already minus 6!
• Part-loops all same radii
• Ignore drift when stalled

23
LOOP/ROLL COMBO'S

• Most widely used
• Immelmann roll is directly after half loop.
  Visible line MINUS 2!
• Early roll MINUS 2 POINTS!
• Humpty bump part-loops all same radii. Falling
  forward over top is severe downgrade
• Rolls always on middle of lines. Minor
  misrelation minus 1 point

24
WIND CORRECTION

• All manoeuveres must be wind corrected
• Shape preserved in models flight path
• All judging on track of model, not attitude
• Pilot must make allowance for lines/angles and
  figures at box ends, or high vertical
  manoeuveres

25
POSITIONING

• Entire flight within box
• Centre manoeuveres oppiste judges on CL
• Off-centre downgraded in range of minus 1 to 4
• Entire manoeuver out- ZERO POINTS!
• Far flying serverely downgraded. Visibility!
• Optimum distance 150m!
• Turnaround manoeuveres downgraded in proportion
  to being out

26
GENERAL

• FAI competition take-off and landing 10 or 0
  points
• SAMAA Competition from 10 to 0 with downgrades
• Gear retracts on landing ZERO!
• Only one attempt at each manoeuver
• Second attempt at take-off scores ZERO!
• Flopped stall tunr scores ZERO POINTS!

27
GENERAL

• Use DEDUCT method for judging not impression!
• Balance with overall impression
• Enter N/O if manoeuver or part is missed
• Dont guess a score!
• Use own judgment! Dont copy scores!
• Dont talk during flight!
• Be objective impartial
• Be consistent accurate
• GET MORE EXPERIENCE!

28
JUDGES

• Always be on time
• Supply your own admin
• Arrive well-rested!
• Use breaks wisely
• Get a comfortable chair
• Use a sunscreen good hat umbrella
• Look after your eyes!
• Dont force your opinions onto others
• Command respect through good judging
• STUDY THE RULE BOOK!

29
FLIERS

• Always make sure your equipment is working
• Dont keep judges waiting
• Always be polite
• Never argue a score ask where you can
  improve
• Dont mutter to your friends protest
  formally if you feel strongly
• Learn to respect judges just like fliers,
  they are fallible in their judgement
• STUDY THE RULE BOOK!
