What is an Altimeter 2992?

An Altimeter 2992 refers to a specific setting on an altimeter that indicates the barometric pressure at sea level is 29.92 inches of Mercury (inHg). This standard setting is used in aviation to ensure consistent altitude measurements among aircraft, particularly when flying at high altitudes. When pilots set their altimeter to 2992, they are referencing the standard atmospheric pressure, which helps in maintaining safe vertical separation between aircraft.
