Class E surface extension revisited
A little late on the discussion (a year and 8 months roughly), but could we bring back to life a dead horse? I had a student bring this issue up during table talk tonight, about needing a clearance to fly through a Class E surface extension. It threw me off so I promised to do some homework. That brought me here.
I spent over an hour reading through the discussion and the references. I ended up in the FAR's under 91.127 (c). It says that if a control tower is present, communication MUST be made prior to 4 nm. However it does not preclude you from making contact with them since they have jurisdiction of the airspace as stated previously in paragraph (a).
The catch is that if there is a LOA between the over-lying control agency and the tower that controls the airport, the tower now bases their control of the Class E from the fact that their airfield is IMC and they control the airspace up to 2500 AGL (usually).
As for the LOA, it is bull that it is not readily available and posted, but you can still get a speeding ticket when you don't know the speed limit. Bottom line the way I see it is that the FAR does give the exception for ATC jurisdiction in paragraph (a). So the airport does have the right to prevent you from passing through VFR, but only up to 2500 AGL.
Please feel free to correct me if I am wrong, I enjoy learning.
