  • Patent number: 4020787
    Abstract: Visual altitude alerting indicator for the altimeter of an aircraft, manually settable at "Before Landing Check List" to alert the pilot through visual cues to the required safe altitudes he must remember to prevent flying below prescribed safe altitudes, and to the altitude where the pilot must apply power to level when landing. The indicator requires no electronic assistance or audio alarms that might confuse the pilot over the many audio alarms presently used on aircraft. The alerting indicator consists of a ring concentric with the pivot for the hands of the altimeter and center of the dial therefor and adjustably movable about the dial and has a series of indicating altitude pointers to be adjusted relative to the dial at "Before Landing Check List" to alert the pilot through visual cues to the altitude he has to remember to prevent flying below prescribed safe altitudes when landing.
