What is PVD on Boeing 777? (Paravisual Display)

The Boeing 777 aircraft is widely regarded as one of the most advanced and innovative airplanes in the world. With its cutting-edge technology and state-of-the-art features, it is no wonder that the 777 has gained a reputation for excellence in the aviation industry. One such feature that sets the Boeing 777 apart from other aircraft is its Paravisual Display, also known as PVD.

The Paravisual Display is a revolutionary system that enhances the cockpit experience for pilots, providing them with vital information in a more intuitive and efficient manner. It is an advanced form of heads-up display (HUD) technology, specifically designed for the Boeing 777 aircraft.

The PVD system uses a transparent glass panel, known as the combiner, situated in front of the pilot’s line of sight. This combiner displays important flight information, such as altitude, airspeed, and navigation data, directly in the pilot’s field of view. The information appears to be floating in front of the actual outside world, allowing the pilot to maintain situational awareness without having to look away from the cockpit.

Benefits of Paravisual Display

The Paravisual Display on the Boeing 777 brings several key benefits to pilots and the overall aviation experience:

1. Enhanced Situational Awareness: The PVD provides pilots with real-time, pertinent information right in their line of sight, ensuring that they are constantly aware of their surroundings. This improves decision-making capabilities, especially during critical phases of flight such as takeoffs and landings.

2. Reduced Workload: By displaying crucial flight data directly in front of the pilot, the PVD reduces the need to divert attention to traditional instruments and displays. This allows pilots to focus on flying the aircraft and monitoring its systems, ultimately reducing mental and physical workload.

3. Increased Safety: The Paravisual Display enhances safety by minimizing the time pilots need to look away from the cockpit. With important information in their line of sight, pilots can quickly respond to any potential threats or emergency situations, thus improving the overall safety of the flight.

4. Improved Efficiency: The PVD streamlines the cockpit workflow by consolidating essential information in one central location. This enables pilots to access critical data more efficiently, leading to quicker decision-making and a smoother flight operation.

Overall, the Paravisual Display on the Boeing 777 significantly enhances the pilot’s ability to fly the aircraft with precision and confidence, while ensuring the safety and comfort of both crew and passengers.

Technical Aspects of Paravisual Display

The Paravisual Display system on the Boeing 777 incorporates several key technical aspects that contribute to its effectiveness and reliability:

1. High-resolution Graphics: The PVD utilizes high-resolution graphics to ensure that the displayed information is clear and easily readable. This allows pilots to quickly interpret the data and make informed decisions during all phases of flight.

2. Advanced Image Generation: The PVD employs advanced image generation technology to create the illusion of information floating in front of the pilot. This technology ensures that the displayed information seamlessly integrates with the pilot’s external view, creating a natural and cohesive visual experience.

3. Configurable Display Elements: The Paravisual Display can be customized to fit the pilot’s preferences and requirements. Pilots have the flexibility to choose the specific flight information they want to be displayed, allowing for personalized and streamlined cockpit displays.

4. Night Vision Compatibility: The PVD is compatible with night vision goggles (NVGs), enabling pilots to seamlessly transition between enhanced vision technology and the Paravisual Display. This compatibility enhances situational awareness during night flights, further enhancing the safety and effectiveness of the system.


The Paravisual Display system, or PVD, is a game-changer in the aviation industry, revolutionizing the way pilots interact with critical flight information. With its ability to enhance situational awareness, reduce workload, increase safety, and improve efficiency, the PVD plays a crucial role in the success and reputation of the Boeing 777 aircraft.

As technology continues to advance, we can expect to see further enhancements and refinements to the Paravisual Display system, further improving the overall cockpit experience and contributing to the safety and success of future aviation endeavors.
