Abstract: A device that provides conditioned air to an aircraft may include a housing with a housing outlet end, a longitudinally collapsible hose that has a hose outlet for attachment to the aircraft and is partially received within the housing, a hose drive for extracting and retracting the hose by selectively pushing the hose in an outward or inwards directions, a drive control for controlling the hose drive, an outward marker attached to the hose, and a sensor for detecting the presence of the outward marker. The hose may have an extracted length that is at least twice a length of the housing. The hose may pass through the housing outlet end. The drive control may be adapted to respond to signals from the sensor to control the hose drive. Further, the marker may be adapted to provide a magnetic signal or a radio signal for detection by the sensor.

Abstract: Device for extracting and collecting air conditioning hoses, has a flexible hose with a perimeter relief, rolled up as a helicoid along the same, a storage body inside which the hose is housed according to a longitudinal shaft of the same and a tractor unit, connected to the storage body, which also has an extraction and collection mechanism configured to extract and collect the hose. The extraction and collection mechanism has one or more helicoidal spindles, in contact with the perimeter relief, each one of which is configured to rotate according to a rotation shaft parallel to the longitudinal shaft, the rotation of which gives rise to a push force on the relief, which causes a linear displacement of the hose along the length of the longitudinal shaft.
