FIGURE 4. SUMMARY OF PILOTS COMMENTS
Subject pilot
comments, as recorded by the pilots on their post-flight questionnaire
forms, are shown below. The excerpts, while not necessarily
direct quotes of individual pilots reflect the general nature
of the comments.
- The pulsing feature of the device is important in drawing the pilot's attention. (3 pilots)
- A different color might be better - red or amber. (2 pilots)
- "X" intuitive for indicating aa closedrunway. (1 pilot)
- Pilot education would be necessary. (1 pilot)
- Since the device is an obstruction, it should only be used when other equipment is on a temporarily closed runway. (1 pilot)
