Current altimeter. The standard temperature at sea level is 15 degrees Celsius (59 degrees Fahrenheit). This site was designed to help you find the height above sea level of your current location, or any point on Earth. Web site of the NWS Aviation Weather Center, delivering consistent, timely and accurate weather information for the world airspace system Section 3. Maintaining a current altimeter setting is critical because the atmosphere pressure is never constant. Altimeters are important navigation instruments for aircraft and spacecraft pilots who monitor their height above Earth’s surface. This site was designed to help you find the height above sea level of your current location, or any point on Earth. § 91. Altitude, or elevation - which is often the preferred term in geography - is the height above the sea level. (a) Each person operating an aircraft shall maintain the cruising altitude or flight level of that aircraft, as the case may be, by reference to an altimeter that is set, when operating— (1) Below 18,000 feet MSL, to— Aircraft Altimeter Introduction An altimeter is a type of barometer which measures the vertical distance to the surface, necessary for a pilot to maintain the desired or assigned altitude during flight.
