Non Standard Class G – Vanished in CONUS!!! Why?

Asked by: 392 views ,
Airspace

I was checking the sectionals and to my surprise ALL non standard class G in the CONUS disappeared!!  Non Standard G = not 700 and not 1200.

The only place where you can find the zigzag blue (non-1200 G) is on coastal waters!

In Central Oregon there was a lot of G starting at 5500MSL, it's all gone.

Why? New radars? ADS-B?

Any NPRM on this?

i guess this is a big deal for professional scud runners that depend on class G

    You are late to the party, The high class G airspace found mostly in the West is all gone. The rational is basically that with RNAV and point to point navigation allow use of much of this airspace and ATC has had issues with IFR traffic transiting these areas as they were class G.

    It was all handled thru the standard rule making process which is required for airspace designation.

    No it hasn’t, at least not quite yet. The big bend area of Texas has some 14,500 G airspace (search for the airport 09TS). There’s also some SE of the SJN VOR, for just two examples.

    For the “zippered” class G, there’s a bunch just north of Las Vegas and some near Yuma, AZ, for two examples of that.

    They amount of this airspace HAS been dramatically reduced over just the last few years for the reasons John states, but it’s still out there.

    There’s a small patch of it near Isle Royale in Lake Superior, and more of it across the border in Canada.
