Abstract
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.
