document: Impact of aviation highway-in-the-sky displays on pilot situation awareness Thirty-six pilots -LRB- 31 men , 5 women -RRB- were tested in a flight simulator on their ability to intercept a pathway depicted on a highway-in-the-sky -LRB- HITS -RRB- display . While intercepting and flying the pathway , pilots were required to watch for traffic outside the cockpit . Additionally , pilots were tested on their awareness of speed , altitude , and heading during the flight . Results indicated that the presence of a flight guidance cue significantly improved flight path awareness while intercepting the pathway , but significant practice effects suggest that a guidance cue might be unnecessary if pilots are given proper training . The amount of time spent looking outside the cockpit while using the HITS display was significantly less than when using conventional aircraft instruments . Additionally , awareness of flight information present on the HITS display was poor . Actual or potential applications of this research include guidance for the development of perspective flight display standards and as a basis for flight training requirements
