What does a primary flight display consolidate for the pilot?

A primary flight display is designed to streamline the critical flight information that pilots need while flying, integrating multiple parameters into a single view. This typically includes essential data such as altitude, airspeed, heading, attitude, vertical speed, and sometimes other important information like flight direction and navigation data. By consolidating this information, the primary flight display reduces the need for pilots to scan multiple instruments, making it easier to monitor the aircraft's performance and situation at a glance. This integration enhances situational awareness and allows for quicker responses during flight.

While other options may mention important aspects of flying, they do not encompass the full breadth of what a primary flight display offers. For instance, altitude and speed information alone do not provide the complete picture needed for effective flight management, nor does the inclusion of weather conditions and navigation cues capture the entirety of the data presented on such a display. Communication with air traffic control, while critical, is not typically a function of the primary flight display itself. Overall, option C best represents the comprehensive nature of the information consolidated within a primary flight display.
