How do pilots typically receive airspeed data?

Pilots typically receive airspeed data through ADC readings, which refers to the Air Data Computer. The ADC processes inputs from various sensors, including pitot tubes and static ports, to calculate the aircraft's airspeed. This information is then displayed on the cockpit instruments, allowing pilots to monitor their airspeed accurately and in real-time.

This method provides precise and reliable data, crucial for safe flight management and adherence to performance metrics. It significantly reduces the pilot's workload compared to alternative methods like manual calculations or visual inspection, which are generally less accurate and can lead to errors. Additionally, radio communication is typically used for other types of essential information sharing, such as weather updates or traffic advisories, rather than to relay flight-specific data like airspeed.
