Types of Enhanced Vision Systems

Our five senses (vision, hearing, taste, smell and touch) are key to keeping us safe. Vision is especially important to a pilot. Vision at night and in Instrument Meteorological Conditions (IMC) can be improved with technology, namely, Enhanced Vision (EV) and Synthetic Vision (SV) technology.  


Enhanced Vision (EV) uses sensors on your airplane to provide a better view. These sensors can be infrared or radar. They are very useful in seeing terrain in weather, or on a dark night. The sensors help you see what is actually in front of the aircraft.


Synthetic Vision (SV) doesn’t use sensors. Instead, it relies on GPS information and a database to create a virtual landscape. SV can create a picture of the flight environment and overlay that picture with aircraft instrumentation. The result is a single image that contains the information you need for safe flight operations. Since this information is not based on direct observation, you’ll need to keep your software and databases up to date.


Display Choices

Most GA systems are displayed through a cockpit Multifunction Display (MFD), or a Primary Flight Display (PFD). A Head Up display (HUD) is a great way of displaying EV/SV information, but it’s very expensive.


Regardless of which display you choose, be sure to become very familiar with it before you use it in real time. It’s a good idea to schedule periodic proficiency training with a CFI who knows the equipment. These training and review sessions will give you the confidence you need to use the equipment effectively.
