Quoting IslandRob (Thread starter): "1328, stop, stop stop!" the controller shouted, according to audio posted on the website LiveATC.net.[Edited 2015-06-17 16:52:56] |
Quoting Okie (Reply 3): Flight Thirty Two Twenty Eight. |
Quoting wjcandee (Reply 2): A real call needs to be made for an end to the simplex voice communications in favor of the duplex system used by pretty much anyone with a decent radio these days. Ends the stepping on each other. |
Quoting bcoz (Reply 5): What's strange to me is the fact that they were using two different runways for takeoffs. I've been flying in and out of MDW for more than ten years and I don't think I've seen that before. |
Quoting wjcandee (Reply 2): One thing I never hear on the tape is the tower telling the aircraft that was cleared to land on the runway to go around. So I guess DL got off the runway fast enough after the abort. The FO is working radios as they line up and wait, and after they abort, it's clearly the CPT communicating. Experienced captain as PF, and still a FU like this... |
Quoting N415XJ (Reply 11): Just wondering- would it be possible to have some sort of annunciator light that goes off in the cockpit, triggered by ATC when the aircraft is cleared to takeoff? |
Quoting N353SK (Reply 12): The FAA is working on implementing Runway Status Lights that are supposed to automatically alert you when the runway is unsafe: http://www.skybrary.aero/index.php/Runway_Status_Lights_(RWSL) |

Quoting OMP777X (Reply 13): What I just heard while listening to the radio transmissions is that the ground controller informed the WN crew ahead of time that there was another flight also about to take off with a similar call sign to theirs. That probably helped them abort much quicker when they heard the call to stop. |
Quoting SPREE34 (Reply 7): How so? Even in duplex, if two speak at once, the listening station can get garble. |
Quoting cjg225 (Reply 10): Avherald says that 4L was being used for landings, not 4R. It's at 0:10 of the LiveATC recording you linked. |
Quoting IADCA (Reply 18): Both cockpits acknowledged the tower after being told there was a similar call sign on the frequency. The call sign mix up is the major contributing factor here, but it seems pretty clear the proximate cause is the DL pilots rolling without clearance. |
Quoting nm2582 (Reply 23): |
Quoting FighterPilot (Reply 24): Unfortunately adding "Alpha" and "Bravo" to the end is not much different than them already being called "Delta" and "Southwest." The main problem lies in the similar flight numbers. |

Quoting ikramerica (Reply 26): The problem comes from parsing 1328 as thirteen twenty-eight rather than 1-3-2-8 1-3-2-8 And 3-8-2-8 Do not sound alike. |
Quoting FighterPilot (Reply 19): As a corrective action will either carrier change their flight number to avoid this in the future, if so, who? |
Quoting nm2582 (Reply 23): does ATC have the ability to reassign callsigns on the fly? |

Quoting nm2582 (Reply 25): I was kind of thinking about it from a human engineering standpoint - lots of people have no idea what you say before you say their name, but as soon as you say their name, they focus in and pay attention. |
Quoting bcoz (Reply 5): What's strange to me is the fact that they were using two different runways for takeoffs. I've been flying in and out of MDW for more than ten years and I don't think I've seen that before. Arrivals on one runway and departures on another, yes.... but not simultaneous departures on intersecting runways. |
Quoting nm2582 (Reply 23): |
Quoting KarlB737 (Reply 34): Yes there was a call sign issue present in this instance but I think it is too risky for MDW to attempt two takeoffs in this fashion. If two planes ever collide at MDW at the intersection guess what the final ruling will be. It will state that there will be one and only one active runway for takeoffs. |
Quoting sprout5199 (Reply 31): Just saying "they need to be Duplex like every body else" shows that you really don't understand how radio communications work. |
Quoting nm2582 (Reply 25): blah blah blah 3828 (misheard as 1328) ALPHA cleared for takeoff. |
Quoting IADCA (Reply 18): There's a recording on liveatc with the full thing, and the warning was both directions. Both cockpits acknowledged the tower after being told there was a similar call sign on the frequency. The call sign mix up is the major contributing factor here, but it seems pretty clear the proximate cause is the DL pilots rolling without clearance. (And afterwards, the WN pilots even checked with the tower to make sure they were in the right, presumably to assist them in determining what to tell their employers.) |
Quoting EA CO AS (Reply 27): Why not address aircraft by their squawk instead? Less likelihood of having similar ones active from clearance delivery... |
Quoting N766UA (Reply 35): However, in instances with similar-sounding callsigns, ATC should alert the aircraft to each other's callsigns, "Southwest 3828 be advised Delta 1328 on frequency," and then address each in the following manner: "Southwest 3828 Southwest" and "Delta 1328 Delta." This is standard procedure and it's in the 7110 |
Quoting jetblastdubai (Reply 45): With airline mergers and consolidations, it is now impossible to simply drop the first digit because carriers have now become so big that all their flights cannot be accommodated by the remaining 3-digit callsigns. |
