Gulfstream Gets a Takeoff-Stall Safety Rule for Its G400
Published Date: 11/10/2026
Rule
Summary
The FAA has set new safety rules for Gulfstream’s GVII-G400 airplane to prevent dangerous stalls during takeoff by adding special flight envelope protections. These rules kick in immediately and make sure this high-tech plane meets top safety standards. Gulfstream and anyone involved with this model should note the changes and can comment by the end of December 2026.

New certification safety rules for GVII‑G400
The FAA issued final special conditions that add safety requirements for the Gulfstream Model GVII-G400 airplane’s electronic flight control envelope protection for takeoff. These special conditions are effective on November 10, 2026 and will be applied as part of the Model GVII-G400 type certification; interested parties may submit comments by December 28, 2026.
Required behavior for envelope protection functions
For airplanes that use envelope protection functions (like the GVII-G400), the FAA requires that those functions must not unduly limit maneuvering or interfere with normal or emergency operations; must have onset characteristics appropriate to the phase of flight; must not cause unsafe characteristics when flight parameters briefly exceed design limits; must not adversely affect control during expected atmospheric disturbances or impede windshear recovery; must avoid adverse coupling when multiple protections activate; and must not hinder recovery from abnormal attitudes.

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.

Starting January 11, 2027, owners and operators of single-engine turbine airplanes and drones get more flexible inspection options and easier reporting rules. These updates cut down paperwork and hassle without risking safety, making life smoother for pilots, maintenance crews, and the FAA. Plus, some maintenance rules got clearer to keep everyone on the same page.
