The FAA has proposed a rule to protect radio altimeters from interference by expanded 5G wireless networks, requiring US operators to replace or upgrade about 58,600 units across fleets. The move would impose a minimum industry bill of $4.5 billion for equipment and retrofits.

Briefing
Immediate capex and operational hit: about 58,600 radio altimeters would need replacement or upgrade, creating at least a $4.5 billion industry bill and potential aircraft downtime while work is performed (direct cost exposure for operators and lessors). See the IATA warning that temporary mitigations are expiring and heightening exposure: https://hype.aero/?story=bce7cab1-de35-414b-9cbc-bd631bfa6d95
Adds pressure to already stretched ATC and FAA investment priorities: the retrofit burden comes as the FAA moves large sums toward telecom and surveillance modernisation and DOT seeks congressional funding for broader ATC overhaul — competing demands for limited public and private capital: https://hype.aero/?story=4552c4df-f7c0-430b-9d8f-263e035a1899 and https://hype.aero/?story=bca20d4e-6e6d-4fb7-8261-62f21ed9c92c
Supply-chain and cost escalation risk: large-scale avionics retrofits during ongoing supply-chain strain could raise total program costs and delay compliance, compounding industry-wide financial impacts noted in recent supply-chain studies: https://hype.aero/?story=ae474751-b542-4c61-9b33-c79f2753895c
