12. Flight Operations: Pilot requirements; Use of oxygen
2026-09-24 — Federal Register
FAA proposes to raise the altitudes at which a pilot is required to don an oxygen mask for commuter and on demand operations, as directed by the FAA Reauthorization Act of 2024, and revise the pilot oxygen mask requirements applicable to general aviation operations in pressurized aircraft. This site displays a prototype of a “Web 2.0” version of the daily Federal Register.
It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov. The documents posted on this site are XML renditions of published Federal Register documents.
Why it matters: Changes and notices published by U.S. authorities can affect the way dangerous goods are classified, packaged, marked, labeled, documented, transported, stored or reported. Hazmat employers should compare the official document with their current procedures and training content before making compliance decisions.
Points to review this week
Companies handling hazardous materials should consider whether any of the developments above affect training, shipping procedures, packaging, marking and labeling, placarding, emergency-response information, incident reporting, storage compatibility, fire protection or environmental compliance. Always verify the underlying facts and effective dates against the original official or publisher source.
