The attitude, airspeed, vertical speed, glideslope and localizer, angle of attack, turn and slip, and wind indicator along with an altimeter, HSI, and accelerometer are displayed on the PFD.

• A. The attitude indicator, AOA, airspeed, altitude, vertical speed indicators
• B. A compass rose or arc that includes a map, glideslope or lateral deviation indicators, and active FMS waypoint information
• C. Aircraft and engine system information and CAS messages
• D. The horizontal situation indicator and NAV source, and localizer

Answer: (A)

The main idea is to know what a PFD (primary flight display) is designed to show: the pilot’s immediate flight status in a compact, easy-to-read format. On the PFD, you want the aircraft’s orientation and the core flight metrics you monitor constantly. Attitude (the artificial horizon) is central because it tells you the aircraft’s pitch and bank. Angle of attack is increasingly included to help with stall awareness. Airspeed and vertical speed indicators show how fast you’re moving and how quickly you’re climbing or descending, while the altitude readout keeps you aware of your height above the ground. Together, these pieces give a clear, essential picture of how the airplane is flying at that moment.

The other items listed—glideslope and localizer (ILS guidance cues), wind indicator, HSI, and accelerometer—are more aligned with navigation guidance, flight management, or system/status displays rather than the core flight status shown on the PFD. They are typically presented on the navigation display or separate cockpit instruments rather than all on the PFD. That’s why the combination that emphasizes attitude, AOA, airspeed, altitude, and vertical speed best represents what the PFD is designed to show.
