Abstract: Height adjustment devices can temporarily and selectively adjust a height of at least a first portion of a first aircraft while the first aircraft is engaged with the height adjustment device. Height adjustment devices may include a ramp configured to engage at least a first main landing gear on at least one side of the first aircraft. The ramp may include a first angled portion, a second angled portion, and a level portion positioned between the first angled portion and the second angled portion. A width of the ramp may be sufficient to receive the first main landing gear, and the height adjustment device may be configured to guide the first aircraft to transition the first aircraft from an entering position to a final position to enable large wingspan aircraft to be parked next to each other in narrower airport gates.

Abstract: Height adjustment devices can temporarily and selectively adjust a height of at least a first portion of a first aircraft while the first aircraft is engaged with the height adjustment device by tilting, lifting, and/or lowering the first aircraft and/or a second, adjacent aircraft. The height adjustment device is at least partially integrated into an apron of an airport where the aircraft are located, and the height adjustment device is configured to guide the first aircraft to transition the first aircraft from an entering position to a final position. The height adjustment device may be configured to position the first aircraft in a level orientation in the final position and prevent interference with the adjacent aircraft while the first aircraft travels such that a wing of the first aircraft passes by an adjacent wing of the adjacent aircraft.
