Abstract: An automatic controlling apparatus of a boarding bridge to match a position of the boarding bridge with an airplane, includes: a light irradiator, an optical sensor, and an actuator. The light irradiator irradiates a light to the airplane. The optical sensor can detect a reflection wave of the light reflected from the airplane. The actuator moves the boarding bridge such that a position of the boarding bridge is matched with the airplane, based on a detection result of the reflection wave detected by the optical sensor.

Abstract: The aircraft with multi-level cabins functioning as a cargo cabin or passenger cabin comprises a first cabin provided with a cargo hatchway which is opened and closed by a cargo door on a fuselage, the cargo door facing towards the cargo cabin; a second cabin which lacks the cargo hatchway, the second cabin being positioned directly above or under the first cabin; and an elevator to convey a cargo item, moved into the first cabin through the cargo hatchway, to the second cabin, and to convey back the conveyed cargo item from the second cabin to the first cabin, thereby the cargo item is moved between the exterior of the aircraft and the second cabin.

Abstract: An automatically controlling apparatus of a boarding bridge to match a position of the boarding bridge with an air-flame, includes: a light irradiator, an optical sensor, and an actuator. The light irradiator irradiates a light to an air-flame. The optical sensor can detect a reflection wave reflected from the air-flame of the light. The actuator moves the boarding bridge such that a position of the boarding bridge is matched with the air-flame, based on a detection result of the reflection wave detected by the optical sensor.

Abstract: This invention is distinguished by the following configuration. The aircraft with multi-level cabins functioning as a cargo cabin or passenger cabin, comprises a first cabin provided with a cargo hatchway which is opened and closed by a cargo door on a fuselage, the cargo door facing towards the cargo cabin; a second cabin which lacks the cargo hatchway, the second cabin being positioned directly above or under the first cabin; and an elevator to convey a cargo item, moved into the first cabin through the cargo hatchway, to the second cabin, and to convey back the conveyed cargo item from the second cabin to the first cabin, thereby the cargo item is moved between the exterior of the aircraft and the second cabin.
