Automated Sweepstakes Entry Form Instructions


(1) enter your name (or choose from list), then click on your Division and Class.

(2) enter the date of the flight in MMDD format. For example, if your flight was on June 3, you enter 0603.

(3) Enter the file name with the flight data. It must be in IGC format (if it is in another format, use a software program to export it as an IGC file). Any flight in the IGC format will be accepted, regardless of what logger or GPS was used to log the flight. No security checking is performed.

(4) Enter your tow release time and landing time, in HHMMSS format. This is taken directly from the IGC file, and must be in UTC timezone. You may have to look at the data file, or use a program like SeeYou to find these points. For example, if your release was at 193546, enter this string of numbers just as they are (this is 19:35:46 UTC = 1:35:46 PM Central Standard Time). Both of these times are needed for the optimizer to know when to credit flight distance. Automatic figuring of these times is impractical. For example, one may release directly into wave without losing altitude or without circling off tow. Similarly, you may be stationary in wave without climbing or sinking, which some programs interpret as a landing! Or you might have left your logger on after th flight, and it records your car drive up/down some mountain roads.

(5) Click the SUBMIT button. In a few seconds, the output from the optimizer program will be displayed. An e-mail will be sent to the 1-26 Sweepstakes Sheriff notifying of your fight.

Problems

Please direct technical problems to Kevin Ford, the author of this web page. If you wish to remove a flight, or replace an existing flight with a new claim, please contact the Sheriff.


In general, the program will accept data files which are partially corupted, either gaps in the log, or obviously incorrect data (e.g. a data point on the equator). The altitude data is not analyzed at all, so it should work equally well with Garmin-logger flights.
