Skyvector - charts

[Rune Jensen]

I found in one of the forums here a link to this brilliant site "skyvector.com" which I found really useful. However I am wondering about the meaning of the colors on the arrows used for world-hi. Some are black and others are blue. Does anybody know the difference?

OK, thank you Ricardo!

Here from their forum:

On the High altitude charts the blue "Q" airways are RNAV (GPS) high altitude routes. The black "J" airways are high altitude VOR routes

On the Low altitude IFR charts the "T" airways are the RNAV(GPS) routes and in blue, whereas the "V" airways are black.

On the VFR charts the V and T routes are the same color (faded blue).
