part of “safety-related events,” some respondents might deduce that there is something inherently unsafe about an approach change inside of 10 miles if the crew did not request it. The response to this question and whether or not there was a potential safety concern could vary greatly, depending on where the change was initiated and on how much of a heading change would be required in the maneuver. Similarly, the question did not allow for the consideration of the type of aircraft involved, since smaller, narrow-body aircraft could more easily accept a change much closer to the runway than could a wide-body aircraft.
