Asked by: 2187 views Airspace

The TFR note on SkyVector for the  TFR 1/1155 surrounding Baltimore/Washington says SFC to OAGL. What does OAGL stand for?

    From the context, I it just means that an AGL altitude is unspecified.

    Many (most?) TFRs specify an AGL value. Good example is the one near Disney World in Florida, “surface up to and including 3000 feet AGL”. If you go to that TFR on Skyvector, you’ll see it depicted as “SFC to 3000 AGL” when you hover.

    OTOH, the SFRA TFR does not have an AGL limit (it goes up to FL180). Whatever script Skyvector uses to parse the TFR, probably looks for an AGL value. There being none, the parser script returns the “O”.
