FAA seeks wireless-industry subsidies to fund $4.5B radio-altimeter upgrades amid 5G interference concerns

The FAA is exploring arrangements under which U.S. cellular providers would contribute to financing roughly $4.5 billion to upgrade tens of thousands of aircraft radio altimeters, according to recently released meeting memos. The moves aim to mitigate operational risks from 5G C-band deployments that can interfere with altimeter signals.

X1.9 flare’s CME sparks S4 radiation storm and G4 geomagnetic storm — widespread satellite, GPS and HF impacts reported On Jan. 19, 2026 an X1.9 solar flare’s coronal mass ejection struck Earth, producing an S4 radiation event—the strongest since 2003—and a G4 geomagnetic storm that generated aurora as far south as the United States. NOAA confirms ongoing satellite anomalies, GPS degradation, HF outages and potential power‑grid effects.
