A rotating retractable step system positioned within a cutout of a wall is presented. The rotating retractable step system comprises a foot pedal and a support shaft. The foot pedal is configured to be stowed in a vertical orientation within the cutout of the wall, and to rotate between the vertical orientation and a horizontal orientation. The support shaft is associated with the foot pedal, such that movement of the support shaft extends the foot pedal outwardly away from the cutout, or retracts the foot pedal towards the cutout.

An Electric Vertical Take-off and Landing (EVTOL) Passenger Air Vehicle (PAV) using a plurality of electric motors positioned concentrically about the passenger compartment and utilizing ducted turbines to produce thrust allowing the vehicle to take off and land vertically and fly without the use of aerodynamic wings. Utilizes a plurality of independent electric battery powered motors providing sufficient thrust to ensure the vehicle can hover and complete a safe landing despite a loss of thrust from any two adjacent motors and up to half of the motors, if non-adjacent, by utilizing redundant onboard flight control systems to vary motor torque as need to maintain steady, controlled flight. Design utilizes a pivoting seat for passenger comfort as well as shock mounting of the seat for safety. Ingress and egress are facilitated by integrated folding air stairs. The turbine fairing is designed to be rapidly manufactured as two parts, as upper and lower shells, using a composite forging process.

A fairing is provided in one example embodiment and may include a first edge portion to provide a first clearance distance between the fairing and rotor flight controls of a rotorcraft; a second edge portion to provide a second clearance distance between the fairing and the rotor flight controls of the aircraft, wherein the second clearance distance is greater than the first clearance distance; and a support structure attached to the fairing below the second edge portion. A rotorcraft is provided in another example embodiment and may include a fairing in which the fairing can include a handhold portion along an edge of the fairing. The handhold portion can include a handhold clearance distance between the handhold portion and rotor flight controls of the rotorcraft; and a support structure attached to the fairing below the handhold portion.

Air stair support systems, stair support cable assemblies, and hooks are disclosed herein. A stair support system includes, but is not limited to, an aircraft fuselage, a door seal, a stair door, and a stair support cable assembly. The aircraft fuselage defines a door frame and a stair hook receptacle. The stair door has a retracted position within the door frame and an extended position that forms an entry/exit stairway. The stair support cable assembly includes a cable and two hooks. The first hook includes a curved end portion configured to hook onto the stair hook receptacle, a cable end portion secured to the cable, and an intermediate portion having first and second intermediate legs that extend the intermediate portion away from the door seal when installed on the door frame and the stair door. The second hook is configured to hook on the stair door.
