<p>The FAA has proposed regulations that would require all radio altimeters (RA) to withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. A new industry/government committee will develop the required methodology and publish the recommended standards in June 2026 for public comment. A final publication is scheduled for March 2027. The FAA said the new regulations, to apply to all new and in-service aircraft that currently require RAs, anticipate the "initial RA performance deadline will be achievable between 2029 and 2032." The agency estimated that some 58,579 new or upgraded RA systems will be required for “all aircraft currently equipped with RA operating under Part 121; the majority of aircraft operating under Parts 91 subpart K, 125, 129, 135, and 194; and a minority of general aviation aircraft operating under Part 91.”&nbsp;Comments on the proposal are due March 9, 2026.</p>
