Requirements for Interference-Tolerant Radio Altimeter Systems
New law requires radio altimeters on drones to be interference-tolerant, affecting BVLOS and operations over people. Compliance needed by 2027.
Aforeworn detected this change in the Commercial Drone (Part 107) Rules space on July 5, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated Medium urgency. All Part 107 operators, especially BVLOS and operations over people should confirm how it applies to their specific situation before acting. There is a time constraint attached: Expected 2027 (exact date pending FCC rulemaking). Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors Commercial Drone (Part 107) Rules continuously and turns every detected change into a plain-English briefing like this one, so you always know first. Forewarned is forearmed.
