Systems and methods for assessing runway conditions are disclosed. The system may comprise a brake control unit having an internal inertial sensor. The brake control unit may be configured to calculate a runway coefficient of friction to assess surface conditions of the runway. The brake control unit may monitor braking in an aircraft to detect a skid condition. In response to detecting the skid condition, the brake control unit may calculate an aircraft deceleration of the aircraft with the inertial sensor. The brake control unit may estimate the runway coefficient of friction based on the aircraft deceleration, an aerodynamic drag force of the aircraft, and a thrust reverse force of the aircraft.

Method and device for estimating lateral speed and lateral position of an aircraft during a phase where the aircraft is traveling on the ground. The device includes a unit for determining an initial lateral position value, corresponding to lateral position with respect to axis of a runway when touching down on landing, a unit for repetitively determining, at least from runway touch down, current ground speed and a current lateral angular deviation, representing angular deviation between the current route and the heading of the runway, a unit for repetitively computing current lateral speed, from the current ground speed and current lateral angular deviation, a unit for computing a current lateral position, from current lateral speed and initial lateral position, and a link for transmitting the current lateral speed and/or the current lateral position to at least one user system.

A device is for assisting the piloting in acceleration of an aircraft in taking in order to control its speed. The comprises a control member, adapted to be actuated by a pilot from a neutral position to define a taxiing piloting command for controlling the speed of the aircraft and a central controller, adapted to operate pilot at least one engine of the aircraft to apply the taxiing command defined by the pilot. The taxiing piloting command is an acceleration or deceleration command of the aircraft during taxiing.

A vehicle and method of operating a vehicle in a vehicle traffic control system includes receiving a grid projection from a grid generator, generating a navigation output, transmitting the navigation output to the vehicle traffic control system, receiving the vehicle traffic control plan from the vehicle traffic control system, and operating the vehicle.

The guiding method such as described correctly guides an aircraft on a platform of an airport, even in complex taxiing areas.

A control method for controlling an electrical taxiing system adapted to moving an aircraft while it is taxiing, the method comprising the steps of: generating a ground speed setpoint for the aircraft; transforming the ground speed setpoint into an optimized speed setpoint presenting a curve as a function of time that has a predefined function comprising a plurality of linear portions, each having a slope that is a function of the ground speed setpoint; implementing a regulator loop having the optimized speed setpoint as its setpoint; and generating a command for the electrical taxiing system from an output of the regulator loop.

An improved monitoring and control system capable of providing automatic control of ground movement in an aircraft equipped with non-engine drive means for autonomous ground movement to enhance airport ground safety and efficient ground travel is provided. The monitoring and control system is installed on aircraft equipped with non-engine drive means controllable to move the aircraft autonomously on the ground and includes monitoring means positioned in locations on the aircraft selected to obtain a maximum amount of information relating to an aircraft's ground position and operation, processor means, data transmission means, and manual or automatic control means to control and direct operation of an aircraft's non-engine drive means to move the aircraft autonomously, safely and efficiently on the ground. The improved monitoring and control system can be employed with one or a number of aircraft simultaneously to increase safety and efficiency of airport ground operations.
