-
- Pilots call it "flicker vertigo" -- it can happen in single engine
- planes (that nice shiny propeller spinning and glinting right in front
- of the pilot), and also sometimes with helicopter blades or
- bounce-back from flashing beacons when in clouds.
-
- I've a book here that says it happens to some people when they watch
- flicker between 4 and 20 Hz. Reactions include nausea, dizziness,
- unconsciousness, or reactions similar to epileptic fit. (Needless
- to say, this is Not Good when you're flying.)
-
- Doesn't give any tips for avoiding it, though, except not to watch the
- flicker, and to make small, frequent changes to the RPMs.
-
- You might try the aviation newsgroups, too -- they might have some
- useful tips 'n tricks.
