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.

In a visual preparatory landing altitude alerting indicator for aircraft and the like and in combination with an altimeter having hands movable thereabout to indicate the altitude of the aircraft, and a rim, visual altitude alerting means for said altimeter and cooperating with said hands to alert the pilot through visual cues of the altitudes that must be maintained to prevent flying below prescribed safe altitudes in preparation for landing comprising a series of circumferentially spaced alerting indicators, means adjustably mounting said alerting indicators for rotatable movement about the rim of the altimeter, and accommodating said alerting indicators to be set to indicate a plurality of critical altitude positions in preparation for landing, and to be adjusted at Before Landing Check List, to remind a crew member to make call-outs at a first predetermined altitude above landing decision height, a second predetermined lower altitude above decision height, a third predetermined lower altitude above decision height and alerting the pilot to apply power to level the aircraft at decision height, including a ring having a plurality of said alerting indicators spaced thereabout, and an annular support forming a bearing mounting for said ring, accommodating the adjustment of said ring about said support, said alerting indicators being spaced about said ring in accordance with the altitudes to be called out for landing and extending inwardly of said ring and the bearing mounting for said ring being a yieldable expansible and contractible ring fitting within the altimeter and held thereto by the expansibility of said ring fitting.
