Rule
Summary
The FAA is updating RNAV Route T-437 in the eastern U.S. to make flying safer and smoother as part of their NextGen plan. Pilots and airlines flying this route will see changes starting December 24, 2026, with no extra costs involved. This upgrade helps keep our skies modern and efficient for everyone.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
T-437 RNAV airway extended to Elkins
The FAA changed RNAV Route T-437 so it now extends between the SIROC, GA waypoint and the Elkins, WV (EKN) VORTAC. The change is intended to improve safety and efficiency and becomes effective at 0901 UTC on December 24, 2026; it provides connectivity for RNAV-equipped aircraft between the Zenith, WV area and Elkins, WV.
No significant costs to operators certified
The FAA states there are no extra costs involved and expects, at most, de minimis costs from compliance or minor flight rerouting. The agency certified the rule does not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.
2026-13440, Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
2026-13126, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.
2026-08943, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.
2025-04846, Extension of the Prohibition Against Certain Flights in the Territory and Airspace of Libya
The FAA is extending the ban on certain flights over Libya for three more years, until March 20, 2028. This affects U.S. airlines, commercial operators, and pilots with FAA certificates flying in Libyan airspace, due to ongoing safety risks. The rule also reminds everyone how to apply for special approvals or exemptions if needed.
2025-03853, Enforcement Policy Regarding “Drug and Alcohol Testing of Certificated Repair Station Employees Located Outside of the United States; Correction”
The FAA is giving repair stations outside the U.S. a break by delaying enforcement of new drug and alcohol testing rules until March 20, 2025. This means affected repair stations don’t have to worry about penalties if they aren’t fully following the updated rules just yet. The delay helps everyone get ready without rushing or extra costs.

Colorado is now in charge of safely managing special wells that store carbon underground to help fight climate change. Starting November 12, 2026, the Colorado Energy and Carbon Management Commission will issue and enforce permits for these wells, while the EPA keeps control over wells on Indian lands. This change means faster, local decisions without extra costs for businesses or the public.
Next: 2026-20848, Use of Salt Substitutes To Reduce the Sodium Content in Standardized Foods
The FDA is changing food rules to allow salt substitutes in many standardized foods, helping companies make lower-sodium options. This move aims to cut heart disease risks by reducing sodium without changing how foods basically taste or look. The new rule kicks in December 14, 2026, and food makers have until November 12, 2026, to raise any concerns, with no big costs expected.
