With Ed plenty!! But I don't think you got the time to hear it!!WHAT, SOMETHING WRONG?
Doing traffic around Atlanta, I usually call from 7-8 miles out. But, I'm juggling five different Class D's, including Dobbins AFB. There's LZU whom I simply advise I'm on the western edge. PDK is a problem only because of heavy corporate traffic into and off the twenties when I cross the interstate a few miles north.What about Class D? Hubby always wants to wait until no more than 12 miles out before calling. What is the rule-of-thumb for Class D?

I should have referred to that. Unless coming from outside of the metro area, there isn't the luxury. I've gotten used to dealing with "close formation", so to speak. But, should I approach one from outside such an area... Yep, call soon as practical.From the AIM:
4-3-2. Airports with an Operating Control Tower
a. ... Initial callup should be made about 15 miles from the airport.
It depends. My general pattern is based on KAPA when can be extremely busy. Waiting too long can result is a very fast 180 when instructed to "remain clear." OTOH, there is such a thing as being too far away and I've heard pilots being told to wait until they were closer.What about Class D?
Fifteen it is, then.From the AIM:

While legally correct, it is operationally silly. Call early and give the tower controller enough time to figure out if s/he can fit you in so you don't have to do a 180 when the controller says, "Aircraft calling Salisbury Tower, stand by one." And it's "two-way communications," not "radio contact."keep in mind the word is SHOULD. That does not mean you absolutely have to call from 15 miles out. It is a recommendation not a hard fast rule. If they meant it that way they would have said, "Initial callup shall be made about 15 miles from the airport"
The only requirement is to make sure you have radio contact prior to entering the class D. Call from one mile out is not going to make you any friends in the tower but it is still within regulations.
You're dating yourself, or the instructor who told you that.I was always taught to call class C around 12 miles out.
Which is what I said if you had bothered to read the whole thing.While legally correct, it is operationally silly.
Yes NosehairYou're dating yourself, or the instructor who told you that.
"Back in The Day", 12 miles out was sufficient time for a Tower (not a Class C Airspace controller) to react and respond. Maybe even an early Class C when ther wasn't much traffic.
But, as you can see from the responses, that just is not sufficient time for the airspace controller to flow you in to the order of things, these days.
The one thing we got here at POA is opinions.I never dreamed this thread would get so many reply's.

Hey! "mmmmmmmmmmm" is off-topic! Start a new thread!Then you haven't hung out on the board long enough... we can take a post that says "mmmmmmmmmmm" and streach a discussion about it for two pages.
I dropped my daughter over at (LAN) Lansing MI. I was always taught to call class C around 12 miles out. In the am when I dropped her off I did that and it was no problem. I came back around 5pm and called 12 out and got a lecture from the controller. She said I know as long as I talk to you before you enter class C its legal but in the future please call 15 out. Now both times the airport was not busy, I did not conflict with any other traffic, so why would she want a call at 15 out?
Obviously, you simply have to notify prior to entry.
Read what I've previously written regarding my own situation flying traffic. Though not recommended, prior to entry is legal. In my particular situation, there's no such thing as having all that distance to call. Take a look at the Atlanta TAC on Skyvector.com.WRONG.
I realize you probably know this is wrong (at least I sure hope you do!), but as a CFI you will need to think very hard about how you word things so that your students don't get the wrong idea.
I think he is calling you on saying "notify prior" instead of the proper "establish two-way communications." Splitting hairs maybe, but they mean different things to different people...I can technically abide by the FARs, enter the class D and never "notify" the tower of anything. On the other hand I could theoretically notify the tower of my intentions well before entering class D and yet bust 91.129(c)...Read what I've previously written regarding my own situation flying traffic.

No Problems with the FBO or drop off, worked well. The thing with Lansing is they seem to not like GA traffic in there. I have heard from many GA pilots who get the feeling that lansing feels we are a bother. I don't get that at Flint or MBS. Now this is just my 2 cents but I hear it from other GA pilots also.

When the D-spaces are so close together that when you clear one you don't have time to call before busting the next one, the two towers usually have a hot line and LOA for handling it if you tell one you're going to the other.I don't have such a luxury juggling between closely located Class D's. As I said, look at the chart on Skyvector..

Complacency, hell! I notify prior to entry because that's all I have time for. And, that is compliant. Reference AIM 3-2-5 (b)(3). When I leave one tower, it's for a duration of at least one other airspace. The change is almost instant but the time it takes to monitor for a moment before calling.Then, you are busting the regs. TWO WAY COMMUNICATION.
I don't care how close the class D's are in your area - All you have to do is say "Peachtree Tower, N1234X is leaving your airspace momentarily, request frequency change."
I hope you're not teaching your students this type of complacency WRT the regs. And I don't know where you get the idea that all you have to do is "notify prior to entry." TWO WAY communications - They must come back, with your tail number. Even "N1234X, stand by" is OK. "Aircraft calling Tower, stand by" is not.
That particular tail number is known as and referred to as traffic watch. The towers expect it during the morning and evening rush hours.Ken,
I don't think that you're "technically illegal", I think that you are in violation of the regs. However, it sounds as if the towers are cognizant of the challenges of the airspace and use their discretion to give you a "pass". How much of that is because they know your tail number? Would they do the same for one of your students? How will you teach the transition to them? And I think that Ron's point about a letter of agreement between the towers may play a role here.
I think it would be a really good idea to phone one of the towers on the land line one of these days and find out just what the official story is. I'd hate to find that some day a new manager came on, saying to the troops "it's time we start ENFORCING these regulations" only to find you caught in the clamp-down. If there's a LOA behind this, however, that seems less likely.
And those LOAs are what allow them to "play together". I'd be very interested in hearing what they say when you get a chance to talk to them about it! And a tower tour is certainly worth it. Try to do one with your students, too!I have no clue about an LOA. There are numerous news choppers who also transition these areas but at a much lower altitude. Metro's helo is usually at 500. That will keep them away from approach areas more often whereas I'm well above. I think it really boils down to all the towers having to "play together" in order to facilitate movement of traffic as required. Usually, it's not an issue.
That's a given. In fact, the main facility for the school I'm headed to for teaching is just a mile away from Atlanta TRACON. The welcome visits. The tower at PDK welcomes visits with students so the student learns what's happening on the other end of the mic.And those LOAs are what allow them to "play together".

AIM 3-2-5 (b) said:3. Arrival or Through Flight Entry Requirements. Two-way radio communication must be established with the ATC facility providing ATC services prior to entry and thereafter maintain those communications while in the Class D airspace. Pilots of arriving aircraft should contact the control tower on the publicized frequency and give their position, altitude, destination, and any request(s). Radio contact should be initiated far enough from the Class D airspace boundary to preclude entering the Class D airspace before two-way radio communications are established.
14 CFR 91.129 said:§ 91.129 Operations in Class D airspace.
(c) Communications. Each person operating an aircraft in Class D airspace must meet the following two-way radio communications requirements:
(1) Arrival or through flight. Each person must establish two-way radio communications with the ATC facility (including foreign ATC in the case of foreign airspace designated in the United States) providing air traffic services prior to entering that airspace and thereafter maintain those communications while within that airspace.
Technically, you could say I'm breaking regs.
It's getting very busy around here. So, I welcome all you cornfield pilots to come on down and check it out.
Busting regs? Nope. If I were doing what they don't want, I'd know about it long before now. Between tracking down the owners of the plane, the traffic watch contractor and the radio stations who hire it done... word's gonna get through.
OK, let's do that:

Look above.Where do you see anything that suggests you only need to "notify prior to entry?"
And, since the AIM is advisory, let's talk about the regs, which have more teeth:
It's done as authorized by ATC between adjoining facilities. From one Class D to the next, I'm talking with someone and I continue with them until authorized to switch. PDK knows I need to switch to MGE in short order. They don't hold on to me any longer than necessary for that vary reason. When I notify the MGE controller I'll be transitioning north, they know I'll need to talk with RYY. When I pass back south, RYY knows I'll be switching back to MGE and MGE is expecting it considering I was on their radar from the moment I talked with them after switching from PDK. As I pass back south and transition to the southwest, MGE KNOWS I'll need to switch to FTY. From that point on, going west and then back east again, I'm on radar with FTY. All four of those Class Ds have radar and I flash them as requested several times during my flight.Originally Posted by 14 CFR 91.129

NOT when ATC authorizes a deviation from FARs or other requirements.It's not "technically" at all. You ARE breaking regs.
It would be very improper to contact one airspace while still on with another. I flew with a student two weeks ago who left Jax Center frequency while my head was turned toward traffic. We then had a discussion about how you never leave your controller until authorized."Cornfield" hah. I'm sure Chicago Approach would laugh at that one... And I've dealt with (and flown through and around) several class B's. Yes, you're busy with all that tower switching, but it's your job to do it right. You do have two comm radios in that bird don't you? Use 'em.
One thing you're completely forgetting... ATC AUTHORIZES ME TO PERFORM THIS PRACTICE!!!! I said already, were I doing ANYTHING not authorized, you can bet your life I would have heard about it by now.Just because they haven't pressed you on it doesn't mean you're not busting them. They have better things to do.
What concerns me much more is that you apparently don't realize you're busting the regs, and that you are going to be teaching people to fly.
Look above.

You can't bust a regulation when you're in one airspace and they clear you to switch. Almost always, I'm still well inside one airspace when I'm authorized to switch.
I'm busting your balls because,
It IS Established!!! Just about every time, I get those magic words, "Five-One-Two-Whiskey-Whiskey, Clear to transition Class D as requested." Either way, I get an authorization to enter prior to entry with them using my tail number. Then, communication is maintained while within until authorized to switch. How do you think I get the authorization to switch?It does NOT say "notify" prior to entry. It says "Establish two-way radio communications" prior to entry. That means you need to hear your tail number prior to entry.
ATC has the authority to direct traffic by whatever means necessary to all traffic in their area for the purpose of safe flight. Unless you know something is blatantly unlawful and/or certainly unsafe, follow the order. They may not always have time to give you a reason. You stated that yourself. However, I've not had any order unreasonble or incapable of following or unsafe. If anything, I get traffic advisories for some traffic clearly not a factor but done as a courtesy CYA.IIRC, ATC cannot legally authorize a deviation from the FAR's. (Unless they say something like "unless authorized by ATC, ..."). I'm sure Ron can weigh in here and point us to something written on that subject.
Then there's FAA Order 7110.65, Control Transfer, 2-1-15:Ensure that the necessary coordination has been accomplished before you allow an aircraft under your control to enter another controller’s area of jurisdiction.
b. Transfer control of an aircraft only after eliminating any potential conflict with other aircraft for which you have separation responsibility.
c. Assume control of an aircraft only after it is in your area of jurisdiction unless specifically coordinated or as specified by letter of agreement or a facility directive.
See above. It ain't happening. The time is too short and it's not worth missing a traffic advisory. Further, do you think Controller A wants you talking to Controller B before there may be a hand-off you're not aware of? Stay with your current controller. Otherwise, you may end up not hearing a much desired traffic advisory or safety alert.True, but you can listen to the other one so you can flip over and jump in right away.
I have no clue where that came from.Actually, there's another reason I'm busting your balls. It's because you said you only have to "notify prior to entry" in this thread which relates not to the airspace you are flying in, but a class C with nothing else around it, which is obviously very much incorrect.
Calm down Kenny. I think that all he was saying is that when posting, it's bad form to use the word "notify" in place of "established 2-way radio communications" (which you in fact did) since newer pilots might think that only half of the required conversation is enough.It IS Established!!!
