õhukõrguse
õhukõrgus refers to altitude, the vertical distance of an object or location above a reference point, typically sea level. In aviation, it is a crucial concept for air traffic control and navigation, ensuring safe separation between aircraft. Different types of altitude exist, including true altitude, indicated altitude, pressure altitude, and density altitude, each serving a specific purpose in flight operations.
True altitude is the actual height above mean sea level. Indicated altitude is what an aircraft's altimeter
In meteorology, altitude plays a significant role in atmospheric conditions. Temperature generally decreases with increasing altitude,
In mountaineering and geography, altitude is used to describe the height of mountains, plateaus, and other landforms.
