I've noticed while looking on high altitude charts different "kinds" of airways, such as A555, UA555, G448, UG448, R32, UL312, UA314, BR32V, etc.

Is there any signifigance as to the prefix/suffix that accompanies these route numbers?

I know J=Jet, AR=Atlantic Route, and presume A=Atlantic.

Thanks.

Correct me if I am wrong, but the route designator prefix defines the type of navigation equipment to be used on each route (I think?)

The differance between A555 and UA555 would be that the U stands for the high altitude route and the other is for lower altitudes.

I could be totally wrong however.

Check in your Jepps, introduction, Enroute Chart Legend/Airway Information.

It's scary how much info is there.
