Easiest way to join Victor airway

Basically the same thing but after you enter the first waypoint (or any waypoint prior to that) just select the airway off of that waypoint.  At that point you can activate any leg on the airway you want.

It's easy to add an airway to a flight plan but you do need to know a little bit about it. Specifically, you need two endpoints, which can be intersections or VORs. The endpoints are like entrance ramps on the freeway; the first is your "on" waypoint, which is closest to the place where you want to get on the airway. The second is the "off' waypoint, where you want to get off.  Select an "on" waypoint that is behind you.

But an "intercept airway" feature would be nice for the circumstances Flying_Monkey described. 
A number of user interface issues to think through, but an interesting problem. Perhaps if the airway could simply be entered in lieu of a waypoint, and the IFD would presents nearby waypoints (and insert a gap if you already had a plan active.)

Really need to know more about where you were going... Likely your flight plan had a destination that was off said airway?... when confronted with this senario what I do is look on the IFD for the airway (you can set them on of off in settings of the base map.  The controller is already vectoring you towards it... touch and drag the magenta line to intercept the airway and confirm your new course that lines up... easy...  once you intercept if you need to readjust your course on the airway you can easily select the vor or other navaid or location you are heading in the flight plan and hit direct to... This is one that causes stumbling in the flight plan and in flight for many... 

Thanks for the replies. All very helpful. I do think that a join Victor airway feature would be nice. Basically, enter a Victor airway and the ifd will show the closest leg of it...Something like that.

That's pretty much what Apiaguy suggested.
