Default Spinner strobing as a "Bird Strike Countermeasure"

The following thread on the Van's Air Force web site was of general enough
interest that I thought it worthwhile to bring it to the attention of other
pilots:

http://www.vansairforce.com/communit...ad.php?t=24147

Would be quite useful if it really worked. Of course there would still be
strikes with inattentive and near-sighted birds. ;-)

I wonder about doing the candy stripe spiral on them, or painting the blades different colors...

There is a design used on the American Airlines (and perhaps others) high
bypass engines that is reported to be effective too. Might check it out at
airliners.com or something. Considering visibility difference and rotation
speed, the design you are testing appears even more visible. My guess is, it
will work.

I rate this things right in there with the old ultrasonic deer
whistles you put in your car grill. Driving down the road was supposed
to put out a noise to scare the deer. Somebody made a small fortune on
those before they proved they don't work.

That's used to let people on the ground know if the engine is still
turning. An engine coasting to a stop is nearly silent and is silent
if you are out on the ramp wearing hearing protection.

At cruise RPM that effect would be completely lost. There's not a
bird or human alive that can discern stroboscopic effects of more than
a couple hundred cycles let alone over a 1000. Most of us can't even
discern 60 cps.

Incorrect. The spiral on the fan hub is a bird deterrent measure. It
has nothing to do with ground personnel.

True, but aren't we talking about 40 cps when the prop RPM is 2400?
