An aircraft stair system is provided with flexible bumpers configured to prevent abrupt impact of the first structure against the second. Each of the bumpers has a flexible body, a base portion, and a lever arm extending out over the base to create a gap and an open mouth.

Airstair systems and associated methods are disclosed. In one embodiment, the airstair comprises a deployable upper step, a primary deployment device and a secondary deployment device. The upper step is movable between a stowed configuration when a door of the aircraft is closed and a deployed configuration when the door is open. The primary deployment device resiliently biases the upper step toward the deployed configuration. The secondary deployment device is movable in coordination with a movement of the door and configured to drive the deployable upper step toward the deployed configuration during opening of the door and during a failure of the primary deployment device.

A mobile platform with a passenger door system having stairs with one or more deployable lower steps and associated methods for deployment and/or stowing of such lower steps are disclosed. In one embodiment, the method comprises using movement of the door to drive a movement of a handrail associated with the stairs, and using the movement of the handrail to drive a movement of the one or more lower steps.

A landing station for an unmanned aerial vehicle includes a landing surface and a centering wheel. The centering wheel is coupled to the landing surface and has a spoke extending therefrom. The spoke is positioned to rotate relative to the landing surface in response to rotation of the centering wheel relative to the landing surface. The spoke is configured to rotate into engagement with a landing leg of the unmanned aerial vehicle to impart centrifugal force onto the landing leg sufficient to rotate the unmanned aerial vehicle toward a predetermined position on the landing surface.

A vertical take-off and landing (VTOL) aircraft provides transportation to users of a network system. The network system may include multiple aircraft or other types of vehicles to provide multi-model transportation. An aircraft may include a fuselage, a truss coupled to the fuselage, and multiple distributed electric propellers coupled to the truss. The distributed electric propellers may be positioned on at least two different planes. The fuselage may include a cabin having one or more seats for the passengers arranged in a configuration that has a compact footprint, provides legroom, provides visibility to surroundings of the aircraft, or facilitates convenient ingress or egress of passengers. The aircraft may open a port cabin door and starboard cabin door for simultaneous ingress or egress of passengers.

An embodiment is a system including an external passenger seating unit comprising at least one seat; and a translation mechanism for translating the external passenger seating unit between a first position in which the external passenger seating unit is stowed in a payload bay of an aircraft and a second position in which the external passenger seating unit is deployed external to the aircraft for accommodating at least one passenger.

A table is incorporated into an aircraft staircase design. The table can be deployed when the stairs are stowed inside the aircraft cabin area. The table is upwardly biased such that when it is released from a locking mechanism the table flips up to horizontal.
