🌦️Meteorologie: Units in the world of flying
Let's dive into the world of units in aviation! How do we measure different quantities in the air? 🛰️
ℹ️Distance flown on a map is measured in nautical miles (1,852 km).
ℹ️Distance determines visibility, describes the meteorological situation and is measured in meters and kilometers.
ℹ️The speed of flight, but also of the wind, for example, is expressed in knots, which are nautical miles per hour (1.852 km/h).
ℹ️Altitude is given in feet (0.305 m), which gives us an idea of the distance from sea level or from the surface of the earth.
ℹ️Air pressure is expressed in hectopascals, which is crucial for the correct setting of on-board instruments for measuring altitude (for example, the so-called QNH or QNE).
Although the combination of these unit systems may seem confusing at first sight, it has its advantages. When communicating and transmitting information via radio, this minimises the risk of confusion between individual parameters, such as altitude and distance, which contributes to air transport safety. 📡
