KTrax

Contributing to KTrax

Over the years, development and operation of the KTrax site has grown to more than just a hobbyist project. As of 2020, we therefore kindly ask you for a moderate financial contribution for processing the Logbook data.

We offer plans for airports (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

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

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

We strongly recommend choosing a plan appropriate for the number of takeoffs you estimate for your airport 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.

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.
