Wanted to know what is the exact procedure to intercept radial after takeoff
Much the same way you were taught to do it in a 172.
I'm really worried that we're having this discussion. I can understand if the OP needs a bit of explanation on the finer points of FMS usage, but seriously, you can't convince me that it isn't faster to just put the information in the RAD NAV page and do it raw data in ROSE VOR mode.
It's really the most basic of IFR instructions.
