AIRCRAFT GRAYWATER EJECTION SYSTEM

摘要

An aircraft having a cabin with a plurality of potable-water-using stations that drain graywater to a transfer tank. The graywater ejection system pressurizes the transfer tank at appropriate times and/or places, so that graywater can be ejected through a drainmast without the help of gravity. This graywater ejection system eliminates the need for a discharge line from the transfer tank and frees the aircraft's fuselage from having an inconvenient port associated with such a discharge line.
