Under 14 CFR § 89.115(a)(4), if an unmanned aircraft using a remote identification broadcast module stops broadcasting its message elements during flight, the person manipulating the flight controls must —
Why: 14 CFR § 89.115(a)(4) requires landing the unmanned aircraft as soon as practicable if it is no longer broadcasting the message elements of § 89.315 — the broadcast-module counterpart to § 89.110(a)(2)'s rule for standard remote identification aircraft.
Flying to a FRIA mid-flight is not the rule's remedy; a FRIA's no-equipment allowance applies to an operation conducted within its boundaries from takeoff, not to an aircraft already airborne elsewhere without a working module.
No altitude-based workaround substitutes for the broadcast requirement; § 89.115(a)(4) requires landing regardless of the aircraft's altitude.
