I don't think they have delusions, you however, may. I don't think you really understand the FAA regulations as it pertains to obstructions.

I think they do, but do not call it as such.

I think you are the one who does not understand it. The FAA has jurisdiction over ALL aircraft, not just certified, and they specifically say that models are aircraft.

But like I said, do not waste your time with us here, PLEASE contact the FAA and set them straight.

I did not say that they have no jurisdiction, just that they have said that we do not come under part 91. If we did we would have to fly above 500 feet not below 400. Please try to read my statements.

OMG! I’m beginning to understand your logic. The light bulb does not provide illumination; it sucks up anti-photons and the absence of the anti-photons allows the photons to illuminate the room. Seriously, just because they (FAA) do not address models under part 91 does not mean they don’t regulate the airspace we fly in. With the exception of class A airspace Class B, C, D, E & G airspace either can or does start at the surface. We (modelers) fly in one of the designated airspaces which are the subjects of this poll.

Read the applicability part of Part 91. It says it applies to each person aboard the aircraft. Our aircraft does not have people on board so part 91 does not apply. The FAA act of 1958 says the FAA has authority over navigable airspace. Navigable airspace and its boundries are not part of the airspace definition but is a major part of Class G airspace. However, there is part 77 which governs obstructions to airspace.

The FAA does not consider model aircraft an "obstruction". They consider them aircraft. Please read their definition of "aircraft". As such, irrespective of falling under Part 91 or not, the FAA has authority over that operation. Hence their ability to ground models in areas of TFR, such as we will have here in LA today.

And this will all be moot since once they publish the new SFAR 107 our relationship to the FAA should be made much more clear.

Yes their definition of aircraft applies to us, but no part 91 does not. Yes they have authority per part 77. That is why they have not regulated us, we fly mostly in non navigable airspace.

What about this airspace? LA area today!

I don't see how that applies to FAA regulations. TSA's are above FAA regulations. TSA's are basically the Federal government excersing emenant domain on a temporary basis. Not differant in total restriction of airspace in Area 51.

KE,
Just FYI I thought you'd like to know; the UAPO is now AFS-407. So in reality (or technically speaking) it isunder the AFS-400 umbrella that you (we) spoke of previously.

Hhmmm. 14 CFR part 91.137 and 91.141

"With the exception of class A airspace Class B, C, D, E & G airspace either can or does start at the surface. We (modelers) fly in one of the designated airspaces which are the subjects of this poll." (phlpsfrnk)

Simply said. Hard to argue with that, and most likely the majority is in Class G.

But if you read the clause you see that the FAA is not the authority. The TSA authority goes back to the 50's or 60's and just recently added to the FAR, but IMO not necessary.

At anyrate I should have said day to day operations. Terrorist threats, and disasters are clearly special cases which need extreme measures.

That is true, but on should look at the difference in this and the navigable airspace in part 77.

The descriptions for a Class B show a set of graduations but it does not say how wide each ring is for a class B airspace.

The skyvector linktook me right to Long Island, were our field is located. The field is in Syosset, on the north shore, directly east from LaGuardia.

Looks like the field is about15 NM from JFK and about15 NM from LaGuardia. I presume these areClass B airspace airport, but how would you tell?So, what kind of airspace does that put me in?
http://skyvector.com/#47-14-3-4287-3487

Lookslike the field isjust outside the dotted linefrom Republic airport. I am guessingthat is about 5 NM.Their web site says they are Class Dairspace.This is mostly private airplanes as far as I know. I am not aware of any scheduled commercial flights out of here. http://www.republicairport.net/pilot-overview.htm

Best I can tell you are in Class G from the surface to 700 feet AGL. Above 700 feet AGL you are in Class E airspace. At 3,000 feet MSL you are into LGA Class B airspace. Looks like you are about 150 to 200 feet above sea level, so the Class B actually starts about 2,800 feet above where you are standing.

my airspace belongs to the usaf or at least they are the only other folk allowed to to fly under five hundred feet

Thanks. That is what Ithink too.

The highest Iget my planes might be 2200 feet, so I don't think Iwill be touching LGA, JFKor Farmingdale airspace.

You may be right if the elevation is the same where he is standing as the airports the class B is from. But if not isn't the Class B airspace based on the elevation of the airport?

I believe only in MOA's and for national emergencies. But they are not ruled by the FAA, but their wing commander wouldn't care to find out they are flying below 500 feet outside of a MOA.

The Farmingdale airspace is Class D, which extends to the surface inside the dotted line, which for the most part is 5 NM (5.75 SM) around the airport when the Tower is in operation. It is a bit smaller to the south of the airport. So for that airspace it is not your altitude that is critical, but your lateral distance from the airport.

No, Class B airspace altitudes are charted as feet above Mean Sea Level (MSL). Class C airspace is based on airport elevation, but on sectionals and terminal area charts is charted using MSL reference. Class B is described as looking like an upside down wedding cake with steps up as you go out from the main airport. Class C is typically a ring that extends from the surface to the top as charted. In addition, Class C is only active when the tower is in operation just like Class D.

Look at MacArthur Field.The top of their Class C is 4100 MSL, or about 4,000 feet AGL. Most altitudes depicted on sectionals are given in feet MSL. Ground based obstructions will show both MSL altitude and AGL height.

In the example above I noted that while they are under Class B airspace that starts at 3,000 ft MSL it is likely only 2,800 feet AGL at their location since they are about 200 feet MSL at their site.

Ok, I missunderstood what you wrote.
