Threat avoidance system and methods using adjustments to built-in values

Abstract

A system for enhancing flight safety of a host aircraft receives an adjustment value from a portable memory device; determines a working value of a parameter in accordance with the adjustment value; and provides an advice for threat avoidance in accordance with the working value of the parameter, a terrain database, and an expected climb gradient capability of the host aircraft. The adjustment value may describe an adjustment to at least one of: an aircraft capability parameter, a flight crew capability parameter, a mission parameter, a threat detection technique parameter, a threat advice parameter, or a threat avoidance parameter. Threats include a risk of colliding with other aircraft, colliding with terrain, and encountering adverse weather conditions.
