What is the purpose of the primary flight display (PFD)?

The primary flight display (PFD) is designed to provide essential flight information directly to the pilot. This display typically includes crucial parameters such as altitude, airspeed, heading, vertical speed, attitude, and navigation indications. The PFD consolidates this information into a single interface, ensuring that pilots can quickly and effectively monitor flight status and performance without having to shift their attention to multiple instruments.

This clarity is vital during various phases of flight, especially during critical situations such as takeoff, landing, and adverse weather conditions. By streamlining information presentation, the PFD enhances situational awareness and aids in decision-making, contributing significantly to flight safety.

Other options do address important aspects of flight operation such as controlling speed, displaying weather, and managing navigation, but they do not capture the comprehensive role of the PFD in presenting vital real-time flight data to pilots.
