Emergency autoland systems for aircraft must be able to apply braking to the landing gear wheels on an aircraft during landing. The present disclosure details an emergency autoland braking system and associated apparatus for aircraft. Separate from a pedal brake or a toe brake system that requires input from a pilot or copilot, the aircraft is equipped with a second braking system powered by an actuator that can pull on aircraft brake cables independently of the pedal brakes while still allowing for input from the brake pedals. The actuator may be commanded by the emergency autoland system on board the aircraft. The system provides an equal displacement to both brake cables and is calibrated to slow down the aircraft uniformly.

Disclosed is a ground movement system for a helicopter having a fuselage and rotor blades fixed to the top of the fuselage, the ground movement system comprising at least three wheels secured below the fuselage of the helicopter, the wheels being retractable during flight; a motor positioned in the hub or on the undercarriage leg of each of at least two of the wheels, wherein each motor is operable to rotate the wheel in forward and backward directions; wherein each motor allows the wheel to rotate freely when unpowered; at least one user interface operable to receive user input commands to control the speed and direction of travel of the helicopter using the ground movement system; and a control arrangement to provide control signals to each of the motors based on the user input commands.
