Multi-Layer Failsafe
ArduPilot monitors every critical system in flight. When something goes wrong, the aircraft knows what to do — automatically.
If the ELRS link is lost for more than 2 seconds, ArduPilot automatically triggers RTL. The aircraft navigates back to its takeoff point, transitions to VTOL, and lands autonomously.
FS_SHORT_ACTN / FS_LONG_ACTN
When battery voltage drops below the configured threshold, the aircraft aborts its mission and returns home. Two thresholds are set — a warning level and a critical level.
BATT_LOW_VOLT / BATT_CRT_VOLT
If the 4G LTE telemetry link drops, the aircraft can either continue its autonomous mission or return home, depending on configuration.
FS_GCS_ENABL
If GPS signal is lost during flight, the aircraft maintains altitude and enters a circling pattern until GPS lock is reacquired. If GPS is not recovered, it performs a controlled descent.
FS_EKF_THRESH
If the aircraft fails to achieve sufficient airspeed during transition from VTOL to cruise, it aborts the transition and returns to hover mode.
Q_TRANS_FAIL
A configurable geographic boundary prevents the aircraft from flying beyond a defined area. If the fence is breached, the aircraft immediately returns to launch.
FENCE_ACTION
Pre-Configured Safety
Every Stork ships with failsafe parameters tuned for its specific configuration. Battery thresholds match the installed pack, geofence is set to a conservative default, and RC failsafe is configured for the ELRS link.
Enterprise customers receive full documentation of all failsafe parameters and can customize thresholds through QGroundControl or Mission Planner.
Safety built in
Every failsafe is configured, tested, and verified before your Stork ships.
