Piloting an aircraft is quite a complex endeavor, requiring one to govern the trajectory of the vehicle, manage various systems, maintain communication with ATC, keep awareness of their surroundings, and so much more at once. One of the most important things that pilots must do to ensure a safe flight is to be constantly aware of their position in the atmosphere, as many things are dependent on altitude, ranging from engine performance to collision avoidance. In order to monitor the aircraft’s exact altitude at all times, one must rely on a standard cockpit instrument known as the altimeter. This instrument is always present in some shape or form within the aircraft, regardless of the type of aircraft you are flying or the type of cockpit your model features. As such, it is important that any current or prospective pilot has a good understanding of such instruments, and how their readings are obtained.
