Boeing 747 and 777 Face New 5G Landing Restrictions

## Summary

The FAA is updating rules for Boeing 747-8 and 777 airplanes because their radio altimeters can get messed up by 5G signals in Canadian airspace. Pilots will have to follow new flight manual limits to keep flights safe starting July 1, 2026. This change helps prevent problems with important airplane systems and keeps everyone flying smoothly, with no big costs expected.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 747-8 and -8F series airplanes and Model 777- 200, -200LR, -300, -300ER, and 777F series airplanes. This AD was prompted by the determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G Lower C-Band) while operating in Canadian airspace, and the determination that this interference may affect multiple other airplane systems using radio altimeter data, including the pitch control laws, including those that provide tail strike protection, regardless of the approach type or weather. This AD requires revising the existing airplane flight manual (AFM) to incorporate limitations prohibiting certain operations requiring radio altimeter data when operating in Canadian airspace. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- AFM Limits for Canadian Airspace: cost, low. If your airplane is a non-radio-altimeter-tolerant Boeing 747-8 or 777 series, you must revise the Airplane Flight Manual (AFM) before further flight in Canadian airspace to prohibit dispatching or releasing to airports, and approaches or landings on runways while operating in Canadian airspace. Th…
- Optional Upgrades To Remove Limits: cost, high. You can remove the AFM operating limitations by modifying a non-radio-altimeter-tolerant airplane to a radio-altimeter-tolerant configuration. The FAA estimates an optional radio-altimeter replacement modification can cost up to $120,000 per airplane; a filter-addition option is estimated up to $14…
- Scope and Administrative Cost Estimate: cost, low. The FAA estimates this AD affects 390 U.S.-registry Boeing 747-8 and 777 series airplanes. For non-radio-altimeter-tolerant airplanes, the AFM revision is estimated at 1 work-hour x $85 = $85 per airplane, with total estimated cost on U.S. operators up to $33,150.
- Tolerant Airplanes Are Exempt: benefit, low. Airplanes that demonstrate radio altimeter tolerance (meeting the PSD tolerance criteria in the AD) are not required to comply with the AFM prohibitions in this AD. Modifying a non-tolerant airplane to a radio-altimeter-tolerant configuration terminates the AFM operating limitations for that airpla…
