Abstract: Methods and apparatus to position a cargo unit in a cargo compartment of an aircraft are disclosed herein. An example linear track system in a cargo compartment of an aircraft includes a first linear synchronous motor (LSM) track coupled to a floor of the cargo compartment, a second LSM track coupled to the floor of the cargo compartment, and a cargo positioning system to activate the first and second LSM tracks to move a cargo unit along the first and second LSM tracks through the cargo compartment. A bottom of the cargo unit has first and second strips of conductive material to interact with the corresponding first and second LSM tracks.

Abstract: Described are systems and methods for magnetically assisted boom refueling. In certain examples, a magnetic refueling receiver is disclosed that includes a refueling receptacle configured to receive a portion of a refueling boom and a receptacle magnet disposed around at least a portion of a perimeter of the refueling receptacle. In another example, a magnetic refueling boom is disclosed that includes a refueling boom structure that includes a first end configured to be inserted into a refueling receiver and a pipe magnet disposed around at least a portion of a perimeter of the refueling boom structure.

Abstract: A seat assembly, a multi-passenger vehicle, and a method for attaching seats to a floor of a vehicle that employ an electromagnetic coupling between the seats and the floor. A power supply supplies electricity to the electromagnetic coupling to secure the seats to the floor and is turned off to release the seats from the floor without tools or workers bending down below the seats to remove coupling devices. The seats can therefore be readily repositioned or rearranged to adjust the spacing between the seats. Resident induction coupling is included between the floor of the vehicle and the seats to provide wireless power to the seats.

Abstract: A floor grid includes an outboard member, a first seat track and a second seat track, a first member extending from the outboard member to the first seat track, a second member extending from the first seat track to the second seat track, a first stanchion extending from the outboard member to the first seat track, a second stanchion extending from the outboard member to the second seat track, a third seat track and a fourth seat track, an intercostal extending from the second seat track to the fourth seat track, a third member extending from the outboard member to the third seat track, a fourth member extending from the third seat track to the fourth seat track, a third stanchion extending from the outboard member to the third seat track, and a fourth stanchion extending from the outboard member to the fourth seat track.
