There is no existing mechanism for the FAA to monitor if there are drone pilots, licensed or otherwise, who will fly above this altitude limit. That is well and fine until you get into a close encounter with a manned aircraft, for which you could be facing heavy penalties if the FAA can identify you as the drone pilot.

Yes, in 2026, the FAA has several high-tech methods to detect drones flying above the legal 400-foot limit. The primary tool is Remote ID, a "digital license plate" system now mandatory for nearly all drones. Remote ID broadcasts the drone's location, serial number, and—crucially—its GPS altitude in real-time, which can be monitored by the FAA and local law enforcement. Furthermore, modern drones from manufacturers like DJI or Autel include "black box" flight logs that record altitude data. Even if a drone isn't broadcasting, airports and high-security areas use Aeroscope and other RF-sensing technologies to track the radio frequency of the controller and the drone, revealing its height and position. The FAA also monitors social media platforms like YouTube and Instagram for footage clearly taken from illegal altitudes. While they may not catch every single violation instantly, the combination of broadcast data and surveillance tech means that flying above 400 feet carries a high risk of detection and potential fines.
