How to read the 3D replay of a paragliding flight
September 09, 2026
To read a paragliding replay, follow the track over time and compare climbs, transitions and terrain. RSFly includes Standard 2.5D Replay in Free; Plus adds cinematic 3D Replay.
What does the 3D replay actually show?
Replay displays track samples and interpolates movement between them. Terrain and camera add context; the scene is neither a video recording nor an exact measurement of ground clearance.
On RSFly.app every uploaded flight includes the Standard 2.5D Replay; Plus adds the cinematic 3D Replay on real terrain, including on mobile.
How do you spot a climb in the replay?
Circles accompanied by altitude gain may indicate a thermal climb. Downwind drift can reflect the wind and does not by itself demonstrate poor centring. Compare altitude changes, duration and context.
Compare segments and flights with similar conditions and recording quality. Observed differences suggest debrief questions without automatically isolating the effect of pilot technique.
What should you look at to improve the next flight?
The replay does not judge: it shows. The conclusions remain yours.
- Transitions: how much altitude you lose between climbs and how fast you travel.
- Decision points: where you left a line that was working.
- Climb consistency: how regular your circles stay from the start to the end of the thermal.
Apply it to your flight
Free includes the logbook, essential statistics and Standard 2.5D Replay. Plus adds cinematic 3D Replay, detailed analysis, comparisons and exports. The Plans page describes current availability and terms.
- Open the IGC file in the logbook and check its date, duration and track continuity.
- Choose a climb or transition and compare time, altitude and replay over the same interval.
- Record observations and compare flights in similar conditions, keeping data separate from interpretation.
In short

- Circles accompanied by altitude gain may indicate a thermal climb. Downwind drift can reflect the wind and does not by itself demonstrate poor centring. Compare altitude changes, duration and context.
