Definition
A cockpit display technology that integrates a computer-generated terrain image (Synthetic Vision) with a real-time sensor image of the outside world (Enhanced Vision, typically infrared) into a single presentation on the pilot's primary flight display. The combined image gives the pilot both the broad situational picture from the synthetic database and the actual sensed view of runways, lights, traffic, and obstacles ahead.
Plain English
A display that blends two pictures of what's outside the aircraft: one drawn by the computer from a terrain database, and one captured live by a camera or infrared sensor. Together they give the pilot a clearer view than either picture alone, especially in poor visibility.
Context Anchor
Seen in advanced flight deck display discussions, especially when studying synthetic vision, enhanced vision, and instrument approaches in reduced visibility.
Derivation
"Combined" signals that two separate vision technologies are merged into one display. The term reflects that CVS is not a new sensor itself -- it is the integration of Synthetic Vision (database-generated) and Enhanced Vision (sensor-generated) into a single picture.
Why Pilots Care
Improves situational awareness and safety by giving pilots a more complete picture than either synthetic or enhanced vision alone can provide.
Grounding Statement
In darkness, haze, or low clouds, CVS helps by showing both a stored-data picture of the outside world and a live sensor picture from the aircraft.
Intuition Check
CVS does not mean the pilot’s normal eyesight plus a display. In this context, “vision” means an aircraft display that creates or senses an outside view for the pilot.
Example Sentence 1
On the approach into fog, the crew used their Combined Vision System to confirm the runway environment before continuing below the decision altitude.
Example Sentence 2
Modern business jets often include Combined Vision Systems to support operations at airports with limited visual references.
