Aircraft Inerting Systems

An airplane fuel tank inerting system provides an inert atmosphere in a fuel tank to minimize explosive ignition of fuel vapor. This AIR deals with the three methods of fuel tank inerting systems currently used in operational aircraft: (1) on-board inert gas generation systems (OBIGGS), (2) liquid/gaseous nitrogen systems and (3) Halon systems. The OBIGGS and nitrogen systems generally are designed to provide full-time fuel tank fire protection; the Halon systems generally are designed to provide only on-demand or combat-specific protection. This AIR does not treat the subject of Explosion Suppression Foam (ESF) that has been used for fuel tank explosion protection on a number of military aircraft. ESF is a totally passive, full-time protection system with multiple and simultaneous hit capability up to 23 mm. The primary disadvantages of foam are weight, reduction of usable fuel, and the added maintenance complexity when the foam must be removed for tank maintenance or inspection.

INTRODUCTION This report is intended to encourage more effort to be directed toWard improving the pilot's visibility from the cockpit of transport type aircraft wih the ultimate objective of improving safety. In the preparation of this Aeronautical Information Report, consideration Was given to pilot surveys made by the Civil Aeronautics Administration, studies made by manufacturers, and a review of the cockpit visibility provided in present day transport aircraf`t. It is recognized that a rigid specification is undesirable and may restrict development and utilization of initiative. For this reason the report is in general terms and offered as a guide.
