Pattern Altitude
I thought I'd have figured this out by now but my observations seems to be contradictory and useless so I'll ask you guys.
For the people we talk to during our flights who is seeing primary & secondary returns and who is seeing only secondary returns?
For example, the way most delta airports in SoCal talk to us leads me to believe they have radar (shared from SoCal I assume) and that the ones outside the Mode C veil can see primary returns.
I remember getting the impression somewhere that TraCons and Centers generally turn off primary returns because of clutter. But if thats true then does that impact their ability to provide advisories WRT non-transpondered craft?
