Any rule of thumb for leading a DME arc? and does anybody teach vectors to an arc? if so, how are you teaching to lead from a vector?

[/ QUOTE ]General rule of thumb for the lead is 1/2 mile for speeds up to 150 KTS, which will cover most GA instrument trainers.

The vectors I seen have usually still involved a 90 intercept, just somewhere other than an IAF. Other than that, if faced with somehting different, it would depend on the intercept angle. At worst, staying with the 90 would gat you in prettg good position for a correction. But that's just thinking out loud.
