Abstract: In a method for the ventilation of an aircraft area, air conveyed from an aircraft environment by a conveying device into an interior space of the aircraft is supplied during ground operation of the aircraft to the aircraft area to be ventilated. During flight mode of the aircraft, air flowing from the aircraft environment via a ram air duct into the interior space of the aircraft is supplied to the aircraft area to be ventilated. During flight mode of the aircraft, in addition to the air flowing from the aircraft environment via the ram air duct into the interior space of the aircraft, air conveyed from the aircraft environment by the conveying device into the interior space of the aircraft is supplied to the aircraft area to be ventilated when a flight velocity of the aircraft falls below a flight velocity threshold value.

Abstract: An aircraft battery exhaust system comprises a fluid discharge opening formed in an aircraft outer skin and a fluid discharge line having a first end connected to the fluid discharge opening and a second end. A first fluid discharge branch line has a first end connected to the second end of the fluid discharge line and a second end connected to a first battery in such a manner that a fluid leaking from the first battery is directed into the first fluid discharge branch line. A second fluid discharge branch line has a first end connected to the second end of the fluid discharge line and a second end connected to a second battery in such a manner that a fluid leaking from the second battery is directed into the second fluid discharge branch line.
