One of the most common causes of incidents and accidents in commercial aviation is still a lack of situational awareness, whether on the ground (runway incursions / taxiway errors) or in the air (landing at the wrong airport / CFIT etc).
Technology that could significantly reduce the frequency of these incidents / accidents already exists. It just needs to be integrated with the existing systems in commercial aircraft. Should the airline industry / manufacturers / regulators be doing more to address this issue?
