(Posted here and in the ATC section b/c I know a lot of you never go there)!
Guys and Gals....
These new 4-character call signs are causing some confusion. Let me set the record straight, so y'all will have an understanding of how this affects you within the ATC system.
On several occasionals recently, ASA has been using their past practice of adding an "A" to the end of your call sign b/c the inbound flight with the same number is still active. When this happens, in the past you simply went from calling yourself ASQ381, to ASQ381A. However, now that your call sign is ASQ4381, when your company adds an "A" to the end, the "4" drops off. The ATC computer can only handle 4-total characters after the company 3-letter identifier. So now your call signs becomes ASQ381A. I have had many, many folks this week try to come out of the ramps as ASQ4381A (Or whatever their 4-character number is plus the "A"). This is incorrect, so if you recieve a clearance and they've appended an "A" to the end, please make sure you have the correct call sign....and use that for your entire flight.
The call sign that will follow you on the Radar (the one the controllers will use) is the one printed on your flight procgress strip. So, save yourself and everyone else confusion, when clearance delivery appends an "A" to your call sign, verify exactly what your call sign is for the entire flight.
And just to add a bit more confusion to this, at ATL ATCT we place the suspense strips at the ground position (after you've picked up your clearance), in numerical sequence (there are usually anywhere from 50 - 100 sitting in front of GC at any one time). So, when you call yourself ASQ4381A, we look two bays over for your strip....rather than looking where the 600-flight numbers would be. When we have to go look for your FP strip, this slows GC down alot.Trust me, some of our new controllers cannot handle this anymore than they can handle the regular traffic without distraction/confusion. Help yourself out by verifying with Clearance Delivery if there's any question! Just trying to make sure we're all on the same page.
Happy Flying.

Very good points. We don't like the new 4 digits either...

Pilots pay attention to you flight plan. Frequently the dispatcher will file you with a letter at then end, and not tell you.
 
Can anyone give me a factual (not opinion) reason why ASA went to these 4-character call signs? Does it have to do with your new ACARS set up? And if so, what happens when you become ASQ381A rather than ASQ4381 in terms of recieving your ACARS messages? Just curious.

Enter it into ACARS the same way it is on the flightplan strip of the release, 381A. Enter it that way into the FMS also.
 
We should just change the regional forum to the ASA bitch forum!!!
 
ICAO..... Can suck it long!

Whenever in Canada, I like to reply to their, "Line up and wait." with "Take it out and hold it."

The official answer is because ICAO mandates using the full flight number as the call sign....In the past however we only did it on some of the international flights....

Does ICAO have the ability to mandate this for flights in the US? It would be nice to go back to the 3 number call sign.....
 
When SKW flies in/out of ATL, they use call signs like SKW58J, or SKW77K. They do not use 4-character call signs like ASQ has begun doing....?! Or were you being sarcastic?

SkyWest has been doing the SKW38B and such for over 2 yrs now out of SLC. Duplicate flight numbers, due to the fact that Delta ran out of them, I suppose. LOL
Homer, I think you are correct.
 
French

The French are purely responsible for this crap. These fools run the ICAO and their only purpose in the world is to cause trouble for those nations who do not suck as much as they do.

These retards agree to make English the universal language of aviation and then half the METAR abbreviations are for French words.

That nation still can't get over the fact that they are unseless to everyone, everywhere.
 
Actually ATC does NOT add the "A." I have no knowldge that the inbound is late or still active. That's your comapny's doing.
Now having said that, I have on occassion had one ot two that the company missed where two aircraft have the exact same number on the same freq....when that happens I generally say "inbound ASQ381, cross rwy 26L..." And for the other I say "Outbound ASQ381, Taxi into position & hold." ALthough the 7110.65 says just to exchange info about similiar (not idential) call signs...I have also on occassion verbally assigned one of them the "A" (usually the inbound b/c they're almost done with that flight segment), but only with an explanation, and then I do not change the strip, I just tell the GC sitting next to me.

Gotchya, but in SLC they use the call sign SKW72S for flt 3872 or SKW3841 would become SKW41A, etc. When the Delta schedule changes, a system is used at the other company to reassign duplicate flt numbers with a letter. This is all done in advance so SKW4004 would become SKW04B until Delta changes the flt numbers and schedules again, etc. So now the software knows it, dispatch files it, ATC recieves it and we all use it except for the customer/reservations and the gate agents. Correct me if I'm wrong but I believe that is how it's done in SLC with SKW.
