Applicable Models:
XAG P150 Max
No. of Affected Aircraft (Reported so-far)

Description of Issues

Under specific operating conditions, the aircraft may unexpectedly enter a hover or stationary state during autonomous operation. In affected cases, communication between the aircraft and remote controller was subsequently lost, preventing reconnection and manual takeover during the occurrence.

The aircraft remained unresponsive throughout the event until the onboard battery level reached the critical protection threshold, triggering an automatic forced landing procedure.

As a result, the aircraft may remain stationaryin-flight for an extended period before descending automatically due to lowbattery protection logic.
