Mission validation guide

What the messages mean

Error

A current mission condition blocks export. Change the affected setting or route and recalculate.

Warning

The mission can export, but a modeled limit or selected behavior needs pilot review.

Info

The planner changed or explains a valid result, such as an adjusted flight count.

Change → Recalculate → ReviewRecalculate the route after a change, then review the message and the new route. A one-click action changes a setting; it does not verify the flight for you.

Supported ranges, such as altitude and waypoint limits, describe what FlyPath can plan or export. Caution margins are planning prompts. Neither establishes a legal altitude, obstacle clearance, safe battery reserve, or permission to fly.

Survey area and coverage

No flight lines and No usable flight path mean the selected area or settings produced no flyable survey route. Check that the boundary is valid and large enough for the chosen altitude, overlap, direction, and margin. A corridor needs a usable centre line and width. Generate or update the route again after editing; an old route is not confirmation.

Front overlap is the estimated overlap between successive images along a survey strip. In semi-auto capture it depends on speed and the interval capture setting; in Full capture mode, the planner controls captures. The planner currently warns below 65% and blocks below 40%. Slow down within the aircraft's supported speed range, increase altitude within supported and legal bounds, or use Full capture with sufficient overlap. Higher altitude changes ground resolution; Full capture can increase time and waypoint count. When even the aircraft's minimum speed cannot reach the target, speed alone cannot fix it. Set safe speed is offered only when a supported speed can meet the target. Recheck the displayed estimated overlap after recalculation.

Battery, waypoints, and flight count

Flight time and battery allowance are estimates based on the planned route and aircraft profile. Near battery limit warns above 85% of the usable allowance. A flight beyond its modeled allowance blocks export and identifies affected flights. Estimated batteries describe the total modeled survey time divided by that allowance, rounded up; configured flights are shown separately. Travel and actual conditions can require more capacity. Split mission can divide the route, but you must recalculate and check every new flight; the action itself does not prove adequate reserve.

Each exported flight must also fit the supported waypoint limit. Adjust Waypoints / flight, split the route, or simplify the survey if a limit is exceeded. Minimum flights is a request: route segments, battery allowance, and the waypoint cap can change the actual count. Flight count adjusted reports a valid result with the requested and produced counts. Review the flight list and every planned start point after any split.

Survey time is a modeled route estimate. Travel to and from the survey, setup, battery swaps, and other ground work are excluded. Plan those separately.

Terrain and altitude

For fixed altitude, terrain checks compare sampled ground elevation with each flight's starting ground reference. Estimated ground clearance below the current 30 m caution margin warns; zero or negative estimated clearance is an error. This margin is not a certified safety threshold. Terrain samples do not account for trees, buildings, wires, or every ground change.

Increase altitude can help when the required setting stays within the supported maximum, currently 150 m. If the required height exceeds that maximum, the error remains: a capped altitude change cannot resolve it. Where available, terrain follow or a revised survey may help. Recalculate and inspect the planned heights and clearance afterward. Check the legal altitude limit for your location independently.

Terrain-follow height exceeds the supported limit reports required heights relative to the affected flight's starting ground reference. Splitting at suitable launch references may bring flights within range, but every resulting flight needs fresh validation. Terrain above flight altitude means sampled ground reaches or exceeds a planned fixed flight height. Revise the plan and recheck. Terrain data unavailable blocks terrain-follow export until valid data returns; without terrain follow, ground-clearance checking may be unavailable. Retry after connectivity or terrain service recovery and inspect the updated result.

Safety actions and export review

Warnings for the selected After mission and Signal lost actions ask you to review what the aircraft will do. Go to setting opens the relevant control; it does not change the choice. Confirm the actual exported behavior and landing location before flight. These warnings appear again in Review and export.

The export review summarizes aircraft, capture mode, altitude, flights, waypoints, and survey time. Its launch assumptions explain the first-waypoint ground reference used for battery and terrain estimates. In semi-auto capture, set interval capture before takeoff. Review the exported mission on the intended controller or DJI application, including each waypoint, height, speed, camera action, and safety action.

When a service or save fails

Connection and terrain messages identify which data could not be loaded. Retry when the connection returns; a terrain-follow mission still requires terrain data before export. If path generation or update fails, use Retry path or Retry update. A previous route may be out of date and cannot stand in for the current settings.

If saving fails, keep your planner tab open and retry after the connection or sign-in is restored. A mission changed elsewhere may need its latest version loaded or a real edit conflict resolved. Export request failures appear in the review dialog, where you can retry the download after recovery. Confirm that errors have cleared and the current route has been recalculated before exporting.
