What is a significant feature of the primary flight display (PFD)?

• A. Shows only speed data
• B. Displays flight data on multiple screens
• C. Consolidates essential flight information onto a single screen
• D. Shows engine performance solely

Answer: (C)

The primary flight display (PFD) is designed to present critical flight information in a clear and consolidated format. This integration allows pilots to have easy access to essential data, such as altitude, airspeed, attitude, heading, and navigation information all on a single screen. This design enhances situational awareness and reduces the need for the pilot to scan multiple instruments, thereby minimizing the cognitive workload during flight operations.

The other options either limit the scope of what a PFD does or do not reflect its primary purpose. For instance, showing only speed data or engine performance solely would not provide the comprehensive information necessary for effective flight management. Displaying flight data on multiple screens is contrary to the purpose of the PFD, which is to consolidate diverse information into one accessible display.
