All the information is in the Sporting code
Read it and know it
Become an official observer.
The information given is a guide only.
Do not assume that an observer knows.
From my observations 50% Observers do
not know some of the basic questions.
Silver

50k / 5 hours / 1000m Gain in height
1% rule
Don’t forget to notch the barograph
You may do an out and return of 100k +
Gold
• 300k / 5 Hours / 3000m gain in height
• The 300k flight may be
• Goal, Out and return, 2 or 3 turning points.
Diamonds
• Goal. 300k Out and return or triangular
course. Getting back to the start location.
You may start in the middle of the leg but
the distance is the distance between the 3
turning points.
• Distance 500k up to 3 turning points. You
do not have to get back home. It can be a
goal flight.
• Gain in height. Get a low point!
Turning points
•The flight path must pass in
the FAI sector that is 45° either
side of the bisector.
•If a logger is used the flight
path is according to the Long
Lat Position declared NOT the
actual location.
Round the clubs
• 4 Turning points
• Beverley air / Cunderdin air / Narrogin Silo
/ Narrogin air
• 3rd Saturday of the month starting October
to March
• Gliders are handicapped and there is a 7%
penalty for carrying water, Take off with
water you have water.
Round the Clubs
• You may turn short provided you fly 100k
minimum, total flight distance.
• If you score the minimum points are 500
the winner gets 1000
• The aim is to score for your club, the more
pilots that fly the more points scored.
• The winning club scores 5 points second 3
third 1 point.
Round the clubs
• Flights are sent to
[email protected] for scoring.
• Scores will be published on
www.jamescooper.com.au together with
the rules. Follow the prompts.
• Contrary to some beliefs there is no
cancellation of a day. One person scores
they win. Know the rules!
Australian Decentralised Comp
And Enterprise
• New rules are being developed to make
the comp more simple, so check them out
on the GFA web page. Not posted yet.
• 1 point per K handicapped.
• 10% bonus for FAI triangles
• 10% bonus for completing a declared task
• You may add a leg before and / or after the
declared flight

200 hours as well as others.
• The best 3 flights of the season will score.

turning points
• 0.8 points per k for the next turning point
• 0.6 points per k for the final leg if 5 tp used
OLC
• The best 6 flights score.
• However you can score for the max
kilometers flown and clubs can score
cumulative kilometers.
AAT’s
Assigned
Area
Tasks
What Are AAT’s
• A semi fixed task
• Flying from as starting point
• Via 2 or more areas that must be passed
through
• Finishing at a finishing point
• The distance flown is measured from the
start to the points in the sectors that give
you the longest flight path.
Time Constrictions
• The time of a task is specified
• If the flight is shorter than the specified
time the flight distance will be scored will
be flight time / allocated time
• If the flight goes over the specified time
there will be no reduction. Distance/Time
flown.
• There may be bonus points for extra
distance flown.
Time Suggestions
• It is generally best to be able to finish a
few minutes over the time allocated.
• It is unusual that you can increase your
average speed by flying for a longer period
of time, because the proportion of the flight
final gliding is reduced.
Where do you fly
• Fly in areas where you will get the best lift
• Do not fly in areas that will give poor lift
• Try to take advantage of streeting lines
For example plan for bad areas, do not get forced to fly into wet areas.
Basic Strategies
• Estimate the speed you will fly today
• And thus the distance you will fly in the
allocated time.
• This is split into two components.
• Final gliding
• Inter thermal
How far will I fly

Let us assume 6000ft start height.
4 Knot Thermals
3 hour task
Glider Dry Astir
NOTE FIGURES ARE APROXIMATIONS
What is
Average Cross Country Speed?
Final Glide Speed?
Calculations Final Glide Distance
• Final Glide at 75 Knots = 135 k/h
• For a height of 6000-(finishing height +
Ground height) =>6000 – (500ft + 750ft)=>
4750ft.
• 4750ft = 1.47k
• 25:1 glide angle.
• 1.47 * 25 = 36K Final Glide
Calculations Final Glide Time
• 36K at 135 k/h = a little over 15 min.
Calculations Soaring
• Time of soaring = Task time – Final gliding
time.
• 3 hours – 15 min = 2.75 hours
• Average cross country speed for Astir in 4
knots 82 kph.
• Distance to fly in 2.75 hours at 82 kph =
225 k
Total distance to fly
• Final Glide distance + Soaring Distance
• 36k + 225k = 261k
• Now Plan where you are going to fly.
Now where to fly
• Do not box yourself
into a corner,
OR
This is better
How do I fly there
• Put into your logger and draw on your
map.
• The centre of the circle.
• The degrees of the sector if applicable.
• In addition put in some turn points that you
intend to use.
• These will help straight line flying. ( More on
this later)
Budget
• Note the time you intend to arrive at the
provisional turning points
Flying Strategy
•
•
•
•
Take a note of your start time
When you can, calculate your finishing time
Fly straight to your first turning point.
As you approach the TP calculate your speed v
your estimate for soaring flight.
• Are you ahead or behind schedule.
• If you are behind be prepared to turn early
• If you are ahead continue straight on to extend
track.
Turn when it is time
Do not fly a curved
path
Flying Tactics
• Now carry on to the next sector in a
straight line to one of the pre selected
turning points.
• Have an idea as to your schedule but do
not spend all the flight calculating
• As you enter the sector work out how far
you are going to fly in.
• When it is time to turn make that decision
and turn.
Coming home
• Now you have decided to come home you
are committed.
• Do not recalculate once you have turned.
• Better to turn back a little late than a little
early.
• Now concern yourself with getting back
Safety
• Despite comments to the contrary the
probability of mid airs is more likely than
with POST tasking and fixed tasks.
• A number of aircraft are in a similar area
but flying in different directions
• Collision courses will be both merging
paths and crossing
