"How to stay out of ATITPPA threads on PoA..."
Kritchlow:
Up until now, I have managed to stay out of these discussions, but I think I might have something at least marginally constructive to add to the thought process. So, please stay with me through this overly-long post.
I get where you're coming from - you're new on the scene (whether arriving or departing), you're moving pretty fast, and you don't know where anyone is. And if we're in each other's way, I definitely want you to know where I am - whatever we have to say on the radio to find out. But I've never been a fan of the "any traffic . . ." request, partly because it isn't what you really mean.
Here's a scenario to illustrate: You are taxiing on to 17 and announce that you will depart the area to the southeast. Plane 1 is abeam the numbers on left downwind for 17. Plane 2 is turning from the 45 into left downwind for 17 with Plane 1 in sight. I'm in Plane 3 inside the outer marker shooting a practice LOC to 35 with a circle to land on 17. (For grins and giggles we could put planes 4 and 5 out to the east and west inbound for landing, but let's leave them out for now.) When I hear you make your departure call, I'm going to be talking as soon as you finish your transmission ("any traffic" request or not). In fact, you and I are going to be coordinating with each other until one of us sees the other one - very politely, I might add. And until you and I find each other, or are otherwise convinced we don't have a conflict, I want Planes 1 and 2 to keep their mouths shut so you and I can talk - and I suspect you do, too. Then, once we find each other, I'll keep talking to you so you know EXACTLY what I'm going to do. Heck, I'll even get out of your way.
In this scenario, you didn't really mean ANY traffic please advise, you meant any traffic that could be a problem, please advise. But Planes 1 and 2 may not have the good sense not to key their mics. In fact, they may be new to this and think they are supposed to respond. Now, maybe there is no harm in them speaking up if you and I still have some time before we're at the same place, but anything either of them says is just going to be useless noise to you, and way down the list of priorities for me. And they might take up time that you and I need. There are all kinds of other scenarios where you might call and I might be "in the area," but I'm not someone you care about because there is no possible way we're going to get anywhere close to each other. In those instances, I'm going to keep my mouth shut when you call, "any traffic" request or not, so the frequency will be open for someone who needs it. I'll continue to make my normal radio calls, if I have any left to make, at normal times. You'll learn where I am at that time, and you won't care that you are just finding out because we're not an issue for each other.
Again, I understand your thought process (I think) - you figure if someone isn't sure whether there is a potential conflict or not, better to have them say something. I agree with that. But if they don't know whether there is a potential conflict or not, they should be talking whether you add the "any traffic" call or not. I certainly would be because I don't want either of us to die. In the end, there are all kinds of "what ifs" and I suspect that whoever came up with the provision in the AIM weighed all the possibilities and concluded that the potential harm of the "any traffic" requests outweighs the potential benefits.
From what I read on airplane forums, many pilots seem to have an emotional response to the "any traffic" request. I wonder if some (not necessarily all) of them have such a response because they consider it insulting. Perhaps what they hear is "I don't trust you to determine whether there is a potential conflict or not, so tell the superior pilot and I'll figure it out." That's a shame if anyone feels that way on either end of the transmission, because you're just trying to do your part to keep everyone safe. For those of us that don't have the emotional response, I think we just have a difference of opinion on whether the request reasonably adds to the mix.
Hope this helps you understand the "anti" point of view. Too bad we can't discuss in person, because I think we would both enjoy the conversation. I'll just close by suggesting that if you aren't convinced not to use ATITAPA, perhaps you could tweak it to what you really mean, "any traffic in my way speak up or move!"
