WebJan 1, 2024 · How Does An Altimeter Work? When the plane starts to climb, the pressure on the altimeter decreases. Because the bellows are compressed, the pressure of air from the static port causes them to expand. As a result, the pointer on the dial rises. WebJan 1, 2016 · The altimeter measures the vertical distance, called range , between the satellite and nadir surface of the Earth (Fig. 1 ). This is conceptually achieved through measuring the travel time of short pulses during emitted to and reflected from the Earth’s surface within the instrument footprint area.
