Fine - but which ones cause you to see the propellers turning in
apparent reverse? Do you frequently operate your airplane indoors?
Propellers are usually observed in natural light, which does not flicker. At
night, on the rare occasions where you actually see the props clearly, it is
from the aircraft's own lighting, which is DC. I have nbever seen the props
turning backwards on a real plane - see it frequently in movies though. . .
Any light that flickers at an appropriate rate will cause the prop to
appear to turn in reverse.
The likelyhood of being somewhere with lights that flicker is irrelevant.
The original statement was that it -ONLY- happens in movies and video, and
that absolute statement is false as are most of MX's absolute statements.
