An efficient, economical and reliable method for preventing aircraft fuel tank explosion and increasing smoke alarm time warning that can easily be newly manufactured or retrofit to existing aircraft systems whereby, pressurized conditioned or unconditioned cockpit-flightdeck-cabin waste outflow air or atmospheric ambient air medium is provided by dedicated aircraft engine systems or off-board air-handling/air-conditioning systems prior to aircraft engine start-up to circulate air in the unoccupied areas of the aircraft to purge and remove fuel tank fumes from within the fuel tank and heat outside the fuel tank and to actively move air in the smoke-alarmed areas of the aircraft for faster alarm-detector response time. After air medium purging of fuel tank fumes or fuel tank compartment heat or circulation of unoccupied smoke-alarmed areas, the fume-laden or heat-laden or circulating air is then vented directly to the atmospheric ambient air or to the low-pressure outside air intake suction areas of the aircraft's propulsive or auxiliary power unit engine for combustion or by-pass airflow to the atmosphere. |
