A method for attenuating effects of turbulence on an aircraft, and a device to implement the method, the method including: using at least one signal on a wind profile signal, along an excitation direction, representing, at a given moment in an aircraft referential, a component along the excitation direction of the wind speed at a front of the aircraft according to a distance along a longitudinal direction of the aircraft; carrying out a frequency determination, in which the wind profile signal is processed to determine a frequential content; and selecting a control strategy to be adopted according to the previously determined frequential content, the strategy enabling at least one applicable control law to be identified.

A system for aiding piloting of an airplane during a final approach includes current roll angle sensors that measures a current roll angle of the airplane, and a maximum roll angle calculation device that calculates a limit roll angle corresponding to a maximum roll angle at which an end point of the airplane will not strike the ground. The system also includes a display for automatically presenting on a single screen a first characteristic sign illustrating the current roll angle and a second characteristic sign illustrating the limit roll angle. If a potential ground collision is presented by too high of a current roll angle, an alarm may be emitted or automatic control of the airplane may occur to correct the roll angle.

A method and device for reducing on an aircraft lateral effects of a turbulence. The device () includes means (, A, A) for calculating and applying a roll control command and a yaw control command enabling the side effects generated by a turbulence event to be attenuated on the aircraft.

Disclosed is a method and device for attenuating lateral effects on an aircraft due to turbulence encountered by the aircraft during flight. The lateral effects are attenuated by applying a roll control order to control a first controllable movable member that acts on aircraft roll and minimizes aircraft roll-wise disturbances due to wind, and a yaw control order that controls a second controllable movable member to act on aircraft yaw. The roll and yaw control orders are calculated based on a sideslip value of the aircraft, while the yaw control order is calculated as a function of the roll control order to compensate for aircraft lateral effects due to turbulence, as well as lateral effects due to application of the roll control order to the first movable member.

Disclosed is a method and device for attenuating vertical turbulence on an aircraft. The method and device involve calculating, by a calculating unit, based on a determined vertical wind component a first control order to control movement of at least one first controllable movable member that acts on aircraft lift, and a second control order that controls movement of at least one second controllable movable member to act on aircraft pitch. A verification unit verifies that activation conditions evidencing severe turbulence are in effect, the vertical turbulence being attenuated.

A device and method for detecting air turbulence determine a theoretical height corresponding to the difference between an extrapolated height of an isentropic trajectory and the current height of an aircraft. This theoretical height is compared with a height threshold indicating a risk of turbulence.
