Altitude Computer

An altitude computer, also known as an aviation computer or flight computer, is a mechanical or electronic device used by pilots and navigators to perform various calculations related to aircraft altitude, airspeed, fuel consumption, wind correction, and navigation. It is an essential tool for flight planning and in-flight calculations.

Altitude computers typically have a circular slide rule or a digital display that allows pilots to input variables such as altitude, airspeed, temperature, and wind speed. By manipulating the slide rule or entering the values into the digital display, pilots can calculate important information such as true airspeed, groundspeed, fuel consumption, time en route, and wind correction angles.

Altitude computers are particularly useful for flight planning, as they can help determine the optimal altitude for fuel efficiency, calculate the time it will take to reach a destination, and provide accurate wind correction angles to compensate for crosswinds. In-flight, altitude computers can assist with navigation by calculating groundspeed and wind correction angles, allowing pilots to stay on course and adjust their flight plan as needed.

Altitude computers come in various forms, including handheld devices, panel-mounted instruments, and software applications for electronic flight bags. They are an important tool for pilots to ensure safe and efficient flight operations.
