![]() "Airbus" wrote in message ... In article , says... Hence the reason an aircraft propeller will appear to be revolving slowly backwards at times. Not when being observed directly. That only happens in movies and video due to the interaction between the imaging rate and the rotation rate of the propeller. Wrong again you clueless twit. No, he is right this time. No he isn't. |

When observed directly under artifical light that "flickers", the most obvious being a strobe light, but there are other types of artificial lights that have flicker. -- Jim Pennino Remove .spam.sux to reply. |

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. . . At least one exception. If you look at a prop through your own prop arc... Bertie |

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. -- Jim Pennino Remove .spam.sux to reply. |
