How to Track Your Glider's Flight Hours and Know When Your Next Service Check Is Due
Your glider is the most important piece of safety equipment you own. Manufacturers publish recommended service intervals — but tracking the numbers manually is where most pilots fall short. A paper logbook with 200 entries is hard to sum quickly. A spreadsheet works until you forget to update it.
FreeFly.ing solves this without any configuration. Add your wing, log your flights, and the app tracks cumulative airtime, flight count, and calendar time automatically — using the manufacturer's own service schedule for your specific model.
No Configuration Required
Most tracking tools require you to find and enter your wing's service thresholds manually. FreeFly.ing skips that step entirely. We maintain a database of manufacturer service schedules — hours, flights, and calendar intervals — for the wings pilots actually fly.
Add your wing by manufacturer and model, log your flights as usual, and FreeFly.ing knows your service timeline. Nothing to look up, nothing to configure.
Why Flight Hours — and Flight Count — Matter
Most manufacturers specify service intervals in hours and calendar time, but some also reference number of flights. Packing and unpacking creates mechanical stress on lines and fabric that's separate from airtime. A wing flown 80 short sledge-run flights may be under more packing stress than one flown 80 long thermalling hours.
Check your wing's documentation for the specific parameters. Common thresholds are:
- Hours: 100–150 hours, whichever comes first
- Calendar: every 12–24 months regardless of use
- Number of flights: some manufacturers specify a maximum number of packing cycles
A glider that sits in the bag for 18 months ages differently than one flown 120 hours in thermal conditions. UV exposure, temperature cycling, and packing stress all degrade porosity and lines. All three parameters count.
Pilots who don't track any of them often discover they've overflown an interval only when a rigger asks at a safety day. By then the wing may have been flying outside its verified performance envelope for months.
Logging Airtime Against a Specific Wing
The key is linking every flight to the gear you flew it on. In FreeFly.ing:
- Add your wing to your gear list (manufacturer, model, year, serial number).
- Each time you log a flight, select that wing from your gear picker.
- The logbook accumulates total airtime and flight count per wing automatically.
You don't need to manually add up hours. Open your wing's gear detail page and the lifetime airtime and flight count are there.
Logging Against a Kit
If you fly a consistent combination of gear — same wing, harness, and reserve — you can create a kit in FreeFly.ing that groups them. When you log a flight against a kit, the airtime is credited to all gear items in the kit simultaneously.
This is useful when you want to track hours on multiple items at once without selecting each piece separately. If you borrow a different harness or reserve for a trip, log those flights against the individual items rather than your usual kit so the hours stay accurate.
Seeing Your Service Status in the App
Because FreeFly.ing already has your wing's service schedule, there's no manual comparison needed. Go to Gear → select your wing → the summary shows lifetime airtime and flights logged alongside your service status.
You can see at a glance where you stand against each interval — hours, flight count, and calendar time — without digging through a manufacturer manual.
Coming soon: Service event logging and automatic threshold alerts. You'll be able to record inspection results directly against a gear item and set service due thresholds — FreeFly.ing will flag when you're approaching them. Log comments on individual flights are also on the roadmap.
Making the Most of Your Inspection Data
After your inspection, log the result against the wing: inspection date, hours at inspection, and any findings. This creates a maintenance history for the wing that lives alongside your flight log. If you sell the glider, the buyer can see the full airtime history and service record — a genuine value-add over a glider with no documented history.
Tracking hours isn't just a safety habit. It's documentation that your wing has been maintained to manufacturer standards. That matters to buyers, insurers, and — most importantly — to you when you're launching in strong conditions and need to trust your equipment completely.
