Ok, hear me out. I have a 430 (non WAAS) and a 330 transponder. I can upgrade the 330 to ES and have the bones of an ADS-B out solution (lacking only the higher fidelity WAAS position source.
That said, I could throw a GDL-82 without upgrading the 330 and because the 82 has a built in WAAS reciever, I'm golden...
So it stands to reason that there should be a stand alone WAAS unit that can make a 330ES transponder and 430 work, shouldn't there?
Question #1. Does a "stand alone" WAAS unit exist?
Question #2. If I elect to upgrade my 330 to ES TODAY, and keep the straight 430 as a half measure for the next year, will I be throwing out an ADS-b signal?
Question #3. If the above answer is "yes" Is there a practical, discernable difference between an ADS-b position derived from a WAAS or non WAAS source, or is it a "legality issue"?
