EASA regulations mandate supplemental oxygen on non-pressurized helicopters above 10,000 feet. Oxygen requirements vary based on helicopter complexity, altitude, and flight duration. Crew always need oxygen above 10,000/13,000 feet. Passengers require oxygen above 13,000 feet, with a percentage needing it between 10,000 and 13,000 feet after 30 minutes.
