PRS-M4DT is AVSS’s recovery kit for DJI M4D and M4TD configurations, including Dock 3 integration and standalone operation. The manufacturer specifies a mass of 215 g ±5 g, automatic deployment in less than 0.5 seconds and manual triggering through DJI’s payload interface. The separately named PRS-M4DTEX adds independent geofence flight termination.
Integration details continue into the software: AVSS’s April 2026 firmware notes address dock-startup errors and barometer handling above mean sea level. Expected descent of 2.92 m/s and impact energy of 8.82 J depend on calculation methods and final compliance reports. The approval reference is the exact aircraft-and-kit combination, rather than the product family name alone.

These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
FAA declaration OOP000000244 is accepted for Category 2 and 3 operations over people for DJI M4TD standalone with PRS-M4DT. AVSS’s accepted means of compliance has a different scope. The earlier rescission for the incompatible Mavic 3 Multispectral/PRS-M3E configuration does not rescind the separate M4TD declaration.
Commercial availability
AVSS markets the kit for specified DJI configurations. The applicable kit version, aircraft setup, firmware, compliance report and jurisdiction define the order, including whether the independent geofence function of PRS-M4DTEX is required.

PRS-M4DT recovery kit for DJI M4D and M4TD — summary: AVSS markets an aircraft-specific parachute recovery kit for DJI M4D and M4TD, including Dock 3 use. The manufacturer specifies a 215 gram system with a plus/minus 5 gram tolerance and manual or autonomous deployment; the separate PRS-M4DTEX configuration addresses European flight-termination requirements.
FAA rescinded DJI Mavic 3 Multispectral with AVSS PRS-M3E at AVSS request due to unsupported/incompatible configuration. This does not revoke separate DJI Matrice 4TD standalone/PRS-M4DT declaration OOP000000244. Neither declaration establishes approval across all variants, jurisdictions or BVLOS missions.
FAA accepted AVSS Means of Compliance revision 6, dated January 7, 2025, for Category 2 and 3 operations over people. Individual aircraft declarations and later MOC revisions require their own applicable acceptance.
Live FAA declaration OOP000000244 is Accepted for Category2 and3 Operations Over People for DJI M4TD Standalone with AVSS PRS-M4DT. That exact aircraft/system declaration does not approve every DJI aircraft, EX variant, operating jurisdiction or BVLOS mission.
