AC 25.795-3 - Flightdeck Protection (Smoke and Fumes)

Document Information

Flightdeck Protection (Smoke and Fumes)
Date issued
Office of Primary Responsibility
ANM-100, Aircraft Certification Service, Transport Airplane Directorate
This advisory circular (AC) describes an acceptable means of showing compliance with the requirements of Title 14, Code of Federal Regulations (14 CFR), part 25, § 25.795(b)(1), “Flight deck protection.” This section requires that an airplane be designed to limit the entry of smoke, fumes, and noxious gases into the flightdeck in the event of detonation of an explosive or incendiary device on the airplane. The means of compliance described in this document provides guidance to supplement the engineering and operational judgment that must form the basis of any compliance findings relative to penetration into the flightdeck of smoke, fumes, and noxious gases generated by explosions or fires elsewhere on the airplane.
