TTT XC League

Announcing the TTT XC League 2017!!
Starting Jan 1st and running though November 30th, TTT members flying from TTT sites can compete for bragging rights of the best XC pilot of the year! Entry is free to all TTT members who wish to participate.

The full rules are posted below. Essentially the rules are: fly XC from the Sequatchie Valley, submit your flight for scoring, and earn points. Your top XC flights of the year will be totaled up for your final score. More details are in the official rules below.

There are a few changes for 2017 (Bold and Italicized), but the highlights of the changes are…  In 2017, we will now be scoring the top 3 flights instead of 5.  This will make more people be at full score capacity and make for a better competition.  Another change is the addition of declared dog-leg flights.  Now your declared turn point XCs will score total distance instead of just launch to landing straight line.  This will make for some more interesting flights and a reward for trying to hit turn points.  This will also give you a taste of true competition type flying.

If interested, send an email to with your details (name, wing type(s), etc.) so we can get you in the scoring spreadsheet and send you a copy of the rules.

Happy XCing!

TTT XC League Rules

If you have any queries about these rules, please contact the TTT XC League Committee at

All flights must be flown on a hang glider or paraglider in the current calendar year. Pilots should submit their flight within one calendar month. Supporting evidence (IGC track log files) if required should also be submitted within one month.

The TTT XC League is open to TTT members using any class of hang glider (HG) or paraglider (PG).  Pilots are responsible for their own safety at all times.  Competing for points is no excuse for unsafe flying.


Flights must start on one of the TTT launches.

Tandem gliders are allowed but only the pilot in command scores.

Any league flight shown to have infringed restricted airspace or designated DNLs will be disqualified.

Flights submitted to the TTT XC League must be supported by a 2D GPS track log that includes launch and landing. This must be uninterrupted, with 3D GPS/barograph altitude evidence, where a flight proceeds under controlled airspace, over any controlled airspace, prohibited areas etc. GPS evidence is not required in the case of Open Distance Witnessed Flights which can be submitted to the league as launch and landing points only. The following conditions apply:

Name and contact details of the individuals who actually witness the launch and landing must be provided.


Accompanying notes

Be aware NOTAMS can introduce temporary restricted airspace.


Flight Types

Only a pilot’s 3 best flights will count.

The minimum flight distance is 5 Miles for a HG and 3 miles for a PG for open distance, and 6 miles for all wing types when flying Out and Back or Triangle routes.

The majority of the flight should be out of ridge lift.


The permissible types of flight are as follows:

Open Distance (score: distance)

Open Distance flights do not have any turnpoints. Open distance flights will score the straight-line distance from the start point to the end point.


Out and Return (score: distance x 2)

Out and Return flights commence at a start point, go round a single turnpoint, and return to the original start point. The coordinates of the start point and finish point are therefore identical. The start/finish point may be different to the actual launch/landing points but the flight distance is only measured from the start, to the turnpoint and back.

Completed Out and Return flights score the distance multiplied by 2, The minimum flight distance is 6 miles.


Triangle (score: distance x 2.5)

A Triangle is a triangular flight as above, except that it does not conform to the FAI 28% rule. Completed Triangle flights score the distance multiplied by 2.5 when the majority of the flight is out of ridge lift. The minimum flight distance is 6 miles.


FAI Triangle (score: distance x 3)

An FAI Triangle is one which satisfies the FAI’s 28% Rule (shortest side must be greater than, or equal to, 28% of the distance flown) and the majority of the flight is out of ridge lift. To fly a triangle you must round three turnpoints, and return to the original start point. The coordinates of the start point and goal are therefore identical and for declared triangles and local records, must be one of the turnpoints. The start/goal point may be different to the actual launch/landing points.

Completed FAI Triangle flights when the majority of the flight is out of ridge lift, score the distance multiplied by 3. The minimum flight distance is 6 miles.

Rule to encourage pilots to attempt triangle flights

Note that for non-declared triangles, using GPS verification, you can fly a loop and you will be scored the best triangle, which can be fitted inside it. Your track log points must cross to complete the loop. This means you don’t have to start and finish at a turnpoint but may start midway along a leg. This is to encourage pilots to try triangle flights.

However for declared triangles the FAI rules still apply, and your start and finish must be at one of the three turnpoints. If you don’t quite manage to get your track logs to cross to complete the loop it may still be possible to score the triangle using FAI rules and FAI Sectors.


Failed Triangle or Out and Back (score: distance)

A Failed Triangle or Out and Back  is an attempt at a triangular or out and back flight in which the pilot fails to make it back to the start point. Failed Triangles or Out and Back score the total distance from the start (Open Distance), around up to two turnpoints and back towards the finish point.


Declared Goal (score: x 1.5)

The pilot prior to launching must declare the start point and goal. Completed goal flights score with a multiplication factor of 1.5.  Declared dog-leg flights that are open distance will be scored total distance from start, through each declared turn point, then to point of landing.  This will make it score better than a dog-leg flight that is not declare (which is just scored from start to landing).


Multiple Flights

There is no need to land between submitted flights provided that complete evidence is provided for each one. For example, you could complete a triangle then fly open distance, or fly round the triangle twice without having to land in between. Note, however, you can only declare one task per flight.

Flight Evidence

The onus is on the submitting pilot to produce irrefutable evidence that the flight they are claiming took place, if challenged. The TTT XC League is designed  to ensure that no unfair play takes place, although in essence it is largely based on trust and relies on pilots entering data accurately and honestly.



Open Distance flights (i.e. no turnpoints) can still be validated with just a take-off witness. If using GPS track log evidence no take-off witness is required.


Track logs

Primary evidence is now considered to be a GPS track log. A track log in the form of an IGC file should be provided, within one month of the flight, to validate the following:

* Flights to Declared Goal

* Out and Return flights

* Triangle flights

See GPS Help for information about recording and downloading your track logs, and submitting a valid IGC file.

The track log must provide unequivocal evidence that no intermediate landing was made and must generally substantiate the flight. Interruptions in the tracklog will not invalidate the flight provided gaps do not bring into question the continuity of the flight (generally speaking gaps of less than 10 minutes are acceptable). Notwithstanding, your track log must include your claimed start point, any turnpoints, and finish point.

Witnesses are NOT allowed for turnpoints (for Out and Return or Triangle flights the start/finish point are considered turnpoints).


Submitting a Flight

Flights should be submitted to a TTT XC League committee member.  GPS Tracks can be submitted via TTT XC League Airtribune page or emailed to  See GPS Help for information about recording and downloading your tracklogs, and uploading a valid IGC file.


Declared Flights

Declared Flights are Flights to Goal, Out and Return or Triangle flights that are declared in advance. You can make your declaration in either of two ways:

Text to another TTT XC League participant



Each of these methods will provide a time-stamp for your declaration that will be valid for 24 hours. You must state: Name, Start location, [optional turnpoints], Goal location, and approximate distance of flight.

For example, a Flight to Goal would be declared as follows:

  • Name, Start, [turnpoints], Goal, Dist.


Example, a flight from Henson Gap to goal at Marion Co Airport.

John Smith, Henson Gap, Marion Co Airport, 25 miles.

You can only declare one task per flight. If you make two separate flight declarations on one day, only the last one is valid. Successful declared flights score the distance flown, multiplied by a specific factor – see Flight Types. This will not show when you first enter the flight, but once the declaration and GPS tracklog have been verified you will be awarded the multiplier.

You should upload your flight to the TTT XC League Airtribune page or email the IGC file to within one month of the flight. See GPS Help for information about downloading your tracklog and submitting a valid IGC file.

Observation Zones

An observation zone is the airspace a glider must enter to verify that a GPS Waypoint (start, finish or turnpoint) has been reached. The shape of the Observation is a standard 400m cylinder. The GPS track log must show that the pilot was in the relevant observation zone. There must be either:

* A tracklog point within the observation zone, or

* A pair of consecutive points not more than 30 seconds apart for which a straight line drawn from the first point to the second point passes through the observation zone.



Cylinders observation zones (‘beer can’) are defined as the airspace in a vertical cylinder of 400 meter radius centered on a GPS Waypoint.


The scored distance will be the distance that is shown as Straight line distance on Airtribune or the distance plotted between launch and landing for non IGC tracked witnessed open distance flights.  For out and back flights or triangles, the distance will be measured between turn points.  Distances will be in statute miles for entering into scoring.  Final score will be the result of distance multiplied by glider factor, type factor and declared factor.


Glider Factors are as follows:

Rigid x 1

Topless HG x 1.1

Double Surface HG x 1.25

Single Surface HG x 1.5

EN C/D PG x 1.25

EN A/B PG x 1.5


The top 3 final scores for each pilot will be added for a total score.  Ranking will be based off of the total score.


GPS Help

GPS tracks should be in ICG format for uploading to Airtribune or emailing to  The TTT XC League Airtribune account username is “” and the password is “xxxxtttxcleague” where “xxxx” is the club lock number (if you don’t know the club lock number, ensure you are a current member and contact a TTT BOD member for the number).


Recording a GPS track

Make sure you know how your instrument records your tracklog before your flight, and that tracklog recording is turned on. For Open Distance it is useful, but not mandatory, to mark your location when you land, to create a reference waypoint for your distance. Alternatively, you can download your track later to a GPS mapping program and determine your best finishing position from the track visualization. This is useful if you have had to fly off-track to make a safe landing, and may prevent those potentially hazardous terrain-hopping moments (no squeaking in TTT XC League) when you try to maximize your distance. A selection of popular GPS mapping/flight analysis programs is shown below:

* CompeGPS Air

* SeeYou

* OziExplorer

* Garmin MapSource

For declared flights you must select your turnpoints before the flight, make a declaration, enter the route into your GPS and fly around the turnpoints in the declared sequence. Your tracklog will be checked to ensure you have entered your declared observation zones at all turnpoints.


Uploading your tracklog

Your tracklog should be submitted within one month of your flight. You can upload your tracklog directly to the TTT XC League Airtribune page at any time. Make sure that you are logged on to the account as described above, select the Upload Tracks button and choose your file to upload, select your type of activity from the “Choose Sport” drop down menu and click Upload.  Next, ensure you click the “Add Story” button and enter your name and pertinent information regarding your flight. From there, your flight and XC data should be available to view.  A courtesy email to should be sent to alert the scorer of your flight being uploaded.


Alternatively, if you email your tracklog to, the scorer will upload your track.  It is up to you to validate the upload and ensure your track is correct.


Tracklog problems

If you find that your displayed tracklog is incorrect (and it shows your car journey home, for example), you can delete it, correct the problem in GPSDump and re-upload it. To delete your tracklog, Click the “…” circle on the header bar for the track and choose delete track.

If your tracklog upload fails, tell us about the problem and email it to:


Opening and Closing Dates


A new TTT XC League contest will start again each January 1st and run to November 30th each year.



Awards (possibly some trophies) and bragging rights will be earned for the top 3 pilots of the year.  Awardees will be recognized at the end of year/Christmas party.
