Patent number: 8249792Abstract: Disclosed is a method and device for protecting an aircraft comprising at least one wing-mounted engine arranged on each of its wings against at least one of a low-energy situation and a high-energy situation during flight in which at least one engine is a failed engine. A control unit is triggered to activate a protection function, as a function of the number and position of failed engines. The control unit controls at least one non-failed engine, and the protection function is activated when activation conditions are met. The activation conditions indicate that the aircraft is either in the low-energy situation such that the total current power of the aircraft is less than a predetermined minimum power or that the aircraft is in the high-energy situation such that the total current power of the aircraft is greater than a predetermined maximum total power.Type: GrantFiled: October 7, 2009Date of Patent: August 21, 2012Assignee: Airbus Operations SASInventors: Emmanuel Blanvillain, Florian Constans, David Chabe

Patent number: 7139645Abstract: A device and process for aiding the driving of an aircraft running over the ground in an acceleration phase with a view to takeoff may include determining a current speed v0 of the aircraft and a value acc corresponding to a deceleration of the aircraft during emergency braking. A distance df to be traveled on the ground by the aircraft while stopping is calculated using the expression df=(v0)2/2 acc, and a stopping position of the aircraft is calculated from the distance df and a current position of the aircraft. Thereafter, the distance df and the stopping position are presented to a driver of the aircraft with the aid of an appropriate device.Type: GrantFiled: July 9, 2003Date of Patent: November 21, 2006Assignee: Airbus FranceInventors: Fabrice Villaume, Eric Godard, David Chabe

Patent number: 6980128Abstract: A display system for an aircraft includes a central unit configured to determine a speed vector of the aircraft and to determine a longitudinal margin of maneuver of the aircraft. The longitudinal margin of maneuver is expressed as a load factor and is related to one of a pitch-up maneuver and a pitch-down maneuver. The display system also includes a display unit connected to the central unit. The display unit includes a display screen configured to display a first characteristic sign illustrating the speed vector and a second characteristic sign illustrating the longitudinal margin of maneuver.Type: GrantFiled: November 19, 2003Date of Patent: December 27, 2005Assignee: Airbus France S.A.S.Inventors: Eric Godard, David Chabe, Jacques Espinasse
