I discovered this when I was multi-time building. I'd file a flight plan from Dallas to Little Rock at 8000ft in a Seminole using Victor Airways. All I had was VOR/DME
, no GPS or RNAV capability. Center would tell us, "Cleared direct Little Rock" as soon as we took off and were clear of the terminal airspace... Well Little Rock was still over 150miles away and I definitely wasn't getting the VOR.
I told center, "Unable direct Little Rock." Center came back with, "Fly 060, direct Little Rock when able." So we flew 060, then about 70 miles later we picked up Little Rock and went direct to Little Rock VOR.
This happened all the time, no matter where I was flying, even though we did all the flight planning on airways, as soon as we took off we were given vector and direct when able.
Bonus animus sit, ab experientia. Quod salvatum fuerit de malis usu venit judicium.
