Acronyms - Roy G Biv

No, this is not a post about the well known Mr. Biv, or colors of the rainbow. Who is Mr. Biv? Well, Roy G Biv is actualy an acronym for the colors of the rainbow.

Red
Orange
Yellow
Green
Blue
Indigo
Violet

Red is the low frequency color and Violet is the high frequency. What does this have to do with flying? Think of this... These are colors.

What important colors are there in aviation? This is a question I missed on a quiz that now, I will never miss again. The colors of Aviation Gas. Yes, Roy G Biv can be a mnemonic for AvGas colors.

Roy - Red - AvGas 80 octane
G - Green - AvGas 100 octane
Biv - Blue - AvGas 100 octane Low Lead
??? - Yellow or clear - Jet A

Anyone knowing the Roy G Biv mnemonic for remembering the colors of the rainbow can now use it to remember AvGas colors.

According to www.prop-liners.com/avfuel.htm there is a newer 82 octane un-leaded that is purple. That sort of throws off my Roy G Biv mnemonic, but what the heck.
