Default Garmin 430 question

wrote in message
...
I was wondering how to program this into the 430, and if it is even
possible. Say you are east of a VOR and ATC gives you a vector to
intercept the 270 radial FROM the VOR and track away from the VOR on
that radial and intercept an airway. The clearance went something
like this:

"Glasair 470XX, fly heading 220, intercept and fly the PDZ 270 to
intercept V394."

Since GPS navigation is TO-TO, how could I get the magenta line on the
screen to be on the 270 radial from the VOR? I guess I could put in
the PDZ VOR as a direct waypoint, then use the OBS button on the 430
and the OBS ring on the VOR head rotate the magenta line drawn from my
present postion to the VOR to rotate and align to the 270 radial. I
would have to set the OBS to 090. That would get the line on the
screen, but I would be flying to the VOR not from it.

How can I do this? BTW, there is no published intersect on V394 that
I am intercepting in this clearance, so I cannot select that waypoint
and fly 270 to it.

Maybe ATC should stop giving these types of clearances and just say
"fly heading 270 and intercept V394".


I don't have the 430, but you should be able to enter a flight plan with
PDZ-V394, push the OBS button and dial in 270. You just might have to fly
the white line instead of the magenta line (assuming the 430 gives you a
white line on the 270 radial and I think it should).

Alternatively you can always just use the NAV receiver, dial in the VOR's
frequency, and do it the old fashioned way which is what I generally do.

ATC is not going to stop giving radial intercepts anytime soon. The
difference between the clearance you got and the clearance you suggested is
ATC knows within reason what path you are going to be on when they put you
on the radial. If they just gave you a vector, they might have to revector
you at a later time which is more work for them. It also makes handoffs
easier as you're flying a known path.
