KTrax

Payment options

Over the years, development and operation of the KTrax site has grown to more than just a hobbyist project. We therefore kindly ask you for a moderate financial contribution for the Logbook data. We offer plans for airfields (recommended) and aircraft.

We decided to keep access to the range analyser free to support safety awareness for FLARM installations.

Free trial

We also offer a free trial for 1 month of the STANDARD plan. Please just send email to Gerhard with your airfield ID.

Payment

Please pay using your credit card using the buttons below. For the PREMIUM plan, you can also pay via SEPA bank transfer if preferred. Please send email to Gerhard for details.

Please specify airfield name/ID and any callsign(s) exactly as they appear in the logbook or in the DDB.

We strongly recommend choosing a plan appropriate for the number of takeoffs you estimate for your airfield per year. An aerotow counts as two takeoffs.

Plans with limited takeoffs run out once the limit is reached. You can always renew within one month without losing any data.

Logbook: Aircraft plan

The aircraft plan below give you access to the web logbook for a year for a specific callsign, wherever you fly and as long as you are covered by OGN stations. Data retention like is like in the STANDARD plan. This plan is recommended only for private owners/operators who fly at several airfields.

Note: The previous distinction between single-seaters, double-seaters and commercial aircraft turned out to be impractical. Also, most single-seaters signed up are modern high-performance self-launch gliders. Therefore, we are offering only one aircraft plan as of 7/2022.

Of course, existing plans will remain to be valid until their expiry.

FAQ

Q: If I sign up, is the access password-protected or public?
A: Your logbook will be publicly visible. As of 2021, crew names can be protected by a simple shared password mechanism.
Q: What happens if an aircraft takes off at a subscribed airfield, then lands on a non-subscribed one, or vice versa?
A: If either the takeoff or landing site is subscribed, both takeoff and landing will be recorded with full data. The 'external' field must be covered by an OGN station providing data to KTrax for this to work.
