Flygunz,
I think the concern was about the onset of anxiety while flying that did not necessarily have an identifiable cause. We can all account for the "normal" concerns about things that happen based upon statistics....engine failures...tail rotor failures, etc. I think the original intent was to seek input from others about those sudden "What am I doing here!" feelings we sometimes get.
Take me to 5-6,000 feet above the terrain in mountainous country....in a JetRanger without a full set of instruments on a smoky/hazy day.....(with adequate visual reference)...and watch me squirm....but in a 212 with a full dash....and no problem. Is it the second engine...the full instrument panel...the seat...or the lack of a good browline/horizion sight in the JetRanger...that gets me?
Interesting statistic out of the PHPA Safety Conference.....our industry kills 59 pilots per year and the rate appears to be increasing. How many airline pilots die in accidents each year?
