An enhanced vision system is provided for an aircraft performing a landing maneuver. Accordingly to non-limiting embodiments, a processor onboard the aircraft receives data from sensors or systems onboard the aircraft and determines a position of the aircraft relative to a runway using the data. Responsive to this determination, the processor adjusts the gain of a first vision system and a second vision system. Images from the first vision system and the second vision system are merged and displayed to the pilot until the completion of the landing maneuver.
