Propeller and Tail Rotor Paint Schemes...

[HeliMix]

I was reading something today about FAA-AM-78-29, Conspicuity Assessment of Selected Propeller and Tail Rotor Paint Schemes. I did a Google search and found the following page (http://amelia.db.erau.edu/gen/am.htm). It has some interesting FAA information on it for many years.

The specific document on FAA-AM-78-29, Conspicuity Assessment of Selected Propeller and Tail Rotor Paint Schemes can be found here in a PDF document (http://amelia.db.erau.edu/reports/faa/am/AM78-29.pdf)

It says:

" At all viewing angles, the propeller design consisting of black and white stripes asymmetrically placed on opposing blades was judged "most conspicuous" by a wide margin. The red and white stripe design (symmetrically placed) was considered slightly more effective than the yellow tip design.

Of two designs for tail rotors, the black and white asymmetrical stripe scheme was chosen "more conspicuous" (9 to 1 ratio) than red, white, and black stripe design."

I think he might be trying to say that black and white are more visible and therefore more safe? Right? If im lost, you should clarify a bit more.

Yes, the is what it appears the FAA is saying.
