Looks like the start of a 60 page (really BORING) read. Anyone distilled it to what applies to non-electrical system equipped planes yet?

Paragraph 3.2

[astjp2]

Hey Hank, you are the engineer, you should love this crap! lol

[waltermrich]

Just as a reminder paragraph 3.2 of the above FAA doc. means airspace not allowed to fly in is the same as the current transponder requirements, right ? Thanks for the doc

Unless you live within 12 nm of coast and above 3000 ft. Aint a problem for my Tcraft, but is for the RV8.

My field elevation is 4470 and I fly regularly at 11K

And you can fly there with a non electrical exempted airplane.

Except its within the 30 mile veil for SLC

I don't understand this and think I see a confusion or conflict between 91.225(d)(4) and 91.225(e)(2).

Is it just me? Has someone else figured out what those two mean?

91.225(d)(4) says exempt from 10K alt. and above.

91.225(e)(2) says operation must be conducted below 10K alt. quote=> "Below the altitude of the ceiling of a Class B or Class C airspace area designated for an airport, or 10,000 feet MSL, whichever is lower".

Don't these two conflict?

Also I wonder what exactly "altitude of the ceiling of a Class B or Class C airspace area designated for an airport" means? Is it really "an airport" as in any airport that exists or some specific airport that is with so many miles of flight?

Dave, It basically means you can not fly over the top of a class C or B airspace. If you look at the map and take the outer ring for either airspace, and extend a cylinder upward you can not operate in that airspace without ADS-B. The exemption allows you to fly within the mode C veil, and under the self of both class B and C airspace. It also allows you to fly above 10,000 feet except for those cylinders I mentioned above.

Tim, thanks for the initial posting. Tom, thanks for the explanation.

[Guest]

Thanks Tom, I think I was making it too complicated but get it now.

91.225(g)(2) says call at least an hour ahead of time for operation without ADS-b out.

Don't want to forget about that one.

Which means that I need to call to fly every time from my home airport? Since it is within the class B veil? that would suck, I would probably just say screw it and fly anyways...

[Guest]

Check it out, maybe I misread it??
