Systems and methods provide a precaution in an aircraft equipped with a terrain avoidance warning system (TAWS). The precaution is provided before a caution and a warning are issued by the TAWS for a subsequent condition to a precaution condition. The systems and methods determine an existence of the precaution condition at least partially in response to an altitude signal and provide a line on a display indicative of a threshold altitude in response to the precaution condition or a bar on an altitude tape of a primary flight display. The line is between a representation of the aircraft and a representation of terrain. The threshold altitude is an altitude at which a caution is issued by the TAWS.
