Well, I’ve heard back from Ms. Lilian Kim at KGO. By way of reminder: this has to do with a story that KGO in San Francisco published about a near hit this past Saturday (26 May 2007), as well as KGO’s reporting and the FAA’s response to being questioned about the incident. I wrote an article Monday (28 May 2007) about it.
Ms. Kim was kind. Probably too kind, given my comments on her story. Here’s what she had to say:
Dear David,
Thank you for alerting us to the errors. The broadcast correctly stated that Ian Gregor was an FAA spokesperson, but when it got transferred to our website, the title was mistakenly changed to FAA controller. We apologize and will make the correction. As for Emrear being spelled Embraer, that was my typo, and I apologize for that as well.
Thank you!
Lilian
Even the subject line of her email was too nice: “Thank You,” it said. Geez. Don’t I feel like an ass…
Anyway, I responded to Ms. Kim, and, because I’m longwinded, I took the opportunity to go on for a moment about what I thought might be problematic here. As always, I look forward to the comments of you, the reader, to help me understand whether or not I’ve gone astray…
You should also know that the KGO online article has been edited to show Mr. Gregor as an FAA spokesman, not a controller, and the aircraft manufacturer’s name is now spelled correctly.
Oh, and before I forget, I’ve had a couple of requests for KSFO’s airport diagram. Here you go!
Anyway, here’s my response (only slightly edited):
Lilian,
What a nice email, especially given the fact that I wasn’t very kind in my blog! However, you’ll want to look at your message (below) again… the proper spelling is Embraer. Your phrasing (“As for Emrear being spelled Embraer…”) makes me worry just a little bit…
I’ll publish a nice update in the blog largely exonerating you
. In the mean time, you really might want to give some thought to why an FAA spokesman would fry this controller before an investigation even begins. To quote:
“This appears to be one of the most serious runway events in San Francisco. The controller should not have cleared an aircraft to land and an aircraft to depart on the same time on those intersecting runways.”
As you probably know, ATC is all about communicating with precision—probably the big reason that controllers hate it when the news media mess up the facts and/or the interpretation of those facts. Given this, we’d be quicker to excuse the spokesman’s first sentence much more quickly than we would his second. Here’s why:
On of the words controllers (even us retired ones–what a hard habit to break!) use very carefully is the word “appear.” If a pilot says “Can you check and tell me whether my landing gear is down and locked?” the controller will always use the word “appear” in his or her answer: “Your gear appears to be down,” or “Your gear appears to be up.” That’s because we have no way of knowing what the status of the gear actually is. All we can do is report on what we see. Hence the mandated use of the term “appear.” That’s why Mr. Gregor can get away with calling this one of the most serious runway events in San Francisco. Not that he’s right. Just that he used a word that we recognize as softening his position. Perhaps that’s something we shouldn’t let go so easily, especially in cases like this, but use of that word hits us where we live.
As for his second sentence, he doesn’t get off so lightly. Clearances to land and take off on intersecting runways can be issued at the same time (and this is something that Mr. Wilson, KGO’s aviation consultant, needs to have in his quiver for times like this as well):
Both of these excerpts are from FAA Order 7110.65R, Air Traffic Control (the air traffic control “bible” in the US) (the bold is mine):
3−9−8. INTERSECTING RUNWAY SEPARATION
Separate departing aircraft from an aircraft using an
intersecting runway, or nonintersecting runways
when the flight paths intersect, by ensuring that the
departure does not begin takeoff roll until one of the
following exists:a. The preceding aircraft has departed and passed
the intersection, has crossed the departure runway, or
is turning to avert any conflict.b. A preceding arriving aircraft is clear of the
landing runway, completed the landing roll and will
hold short of the intersection, passed the intersection,
or has crossed over the departure runway.3−9−5. ANTICIPATING SEPARATION
Takeoff clearance needs not be withheld until
prescribed separation exists if there is a reasonable
assurance it will exist when the aircraft starts takeoff
roll.
So, Mr. Gregor has made a broad statement which obscures rather than illuminates. Controllers clear aircraft to land and depart on intersecting runways all the time, and do it legally and safely. This is to say, the truth might be in there, but he hasn’t gone to a lot of trouble to show us where it is. In any case, he should not have made damning statements in advance of an investigation. And, as I mentioned above, you should be asking yourself why he did so. It may be related to the current anti-controller crusade in the FAA, or he may simply be incompetent. Me, I can’t say which is the case. However, he was out of his depth and had no business making these sorts of statements on behalf of the FAA before investigations were complete.
And to reiterate one more point, in light of the regulations governing simultaneous arrivals and departures on intersecting runways, your Mr. Wilson needs to be careful about his statements as well. I have no doubt that his mistake was simply a matter of not being properly informed, but the fact is, when he says:
“The rule is that this aircraft that is landing, has to be through this intersection at these two runways, before this departing airplane even gets clearance to start rolling for it to takeoff. Apparently that was not the case.”
…he is incorrect. That’s not “the rule.” A takeoff clearance may be issued to the departing aircraft if, in the controllers estimation, appropriate separation will be in place when the departure begins its takeoff roll. Anticipated separation is one of the reasons controllers deserve the big money. Any monkey (hell, a machine) can clear one aircraft for departure after the arrival has cleared the intersection, but it takes judgment and experience to be able to anticipate that sort of separation hundreds of times per day. That’s what air traffic controllers do all over the world, and you’re very lucky to have some of the best at SFO.
Mr. Wilson is quoted two more times:
ABC7 aviation consultant Ron Wilson says the unique layout of SFO makes air traffic control work tedious. As the intersecting runways can often create a confusing situation.
Ron Wilson, ABC7 Aviation Consultant: “All the airplanes are not landing and taking off in the same direction so the looking at the same place all the time. At SFO you have to look at different places.”
First, I’d point out that ATC at SFO is anything but tedious. I’d suggest you schedule a visit to the tower to see what I mean. These men and women earn their pay every single day. Weather, the proximity of SQL, OAK, and SJC, noise abatement, helicopter and fixed-wing transitions, and hell, being the major airport at one of the world’s most popular destinations, mean lots of complex traffic. These folks are not bored.
Second, controllers never look at the same place all of the time. They are constantly scanning and keeping that information alive in their minds. That’s the nature of the job. If the implication is that the controller here was looking at a departure and forgot an arrival, or vice versa, I’d say that that implication is probably incorrect. I’ll wait for the report myself, but I’d guess that something else was afoot.
Bottom line, remember that you’re very lucky to have the kind of talent in the tower at SFO that you’ve got there. Again, I encourage you to spend an hour in the tower cab, plugged-in with the local controller, watching the operation and asking questions. I’d also suggest that you ask the Facility Manager whether one of the controllers at SFO might sit down with you for an in-depth interview about what they do there and how they do it. Personally, I was the subject of one of those interviews myself more than 20 years ago (as a controller at another location) and it came off very well. No sensationalism, just a better understanding for the community.
Finally, know that, if this controller screwed-up, he or she screwed-up. Period. Other controllers accept that. What we don’t accept is the FAA making conclusary statements the day after an incident. That is the height unfair treatment.
Thanks again for the nice email.
Dave
So, dear reader, do I need to reel it in or am I on the right track? Your input is, as always, appreciated.
