CA 2606667

Systems, methods and computer program products for alerting a flight crew during landing that the tailwind exceeds acceptable limits. The system determines a base tailwind threshold speed for a candidate runway based on a performance constant associated with an aircraft and candidate runway information and determines present tailwind speed. If the tailwind speed is greater than the base tailwind threshold speed, a tailwind alert is generated. Also, the system determines if the aircraft is in a tailwind alerting mode based on configuration of the aircraft and activates tailwind alerting, if it is determined that the aircraft is in the tailwind alerting mode.

Systèmes, procédés et programmes informatiques destinés à avertir l'équipage pendant l'atterrissage que le vent arrière dépasse les limites acceptables. Le système détermine une vitesse limite de vent arrière de base pour une piste candidate à partir d'une constante de performance associée à un aéronef et d'informations sur la piste candidate, et détermine la vitesse actuelle du vent arrière. Si la vitesse du vent arrière dépasse la vitesse de seuil du vent arrière de base, une alerte de vent arrière se déclenche. Par ailleurs, le système permet de déterminer si l'aéronef se trouve en mode d'alerte de vent arrière compte tenu de la configuration de l'appareil et déclenche une alerte s'il s'avère que l'aéronef se trouve dans le mode d'alerte de vent arrière.
