Abrupt Controller

Kobra - 07 Aug 2008 14:27 GMT
Flyers,

I'll run this scenario past the group and see what you all think and is if
Mr. McNicoll can shed some light as well.

First, some quick background.  At my airport if you are IFR and are heading,
say, southwest (as I was) it's too bad...you're clearance is to send you 22
miles north to a fix and then 15 mile east to another fix and then they will
turn you on course.  Usually, if asked, you can get direct on course shortly
after take-off.  If traffic permits they will clear you to go direct to your
first filed fix on course.

Ok so...I took-off on an IFR flight plan and I had just leveled off at 4000'
north bound for their fix.  Next they gave me a vector of 090.  After a
minute or so I asked the controller, "McGuire Approach, Cardinal 07G, any
chance direct Smyrna (ENO)?"  The response I got was, "07G direct Smyrna
unable."  Ok...that would be fine if that was what my busy brain heard, but
I did not hear it that way...my brain heard, "07G direct Smyrna 'when
able'."  Shortly after I turned direct for ENO I got a VERY large lecture
with unneeded and unnecessary attitude.  "07G I TOLD YOU STAY 090.  CAN'T
YOU LISTEN OR UNDERSTAND ATC INSTRUCTIONS?  WHEN I GIVE YOU A VECTOR YOU ARE
TO FOLLOW IT EXACTLY AND CAREFULLY!!"

When I explained to him that I heard him say, "...direct ENO when able."  he
became even more belligerent.  "I DID *NOT* SAY THAT!!  YOU NEED TO LISTEN
TO ATC INSTRUCTION MORE CAREFULLY AND FOLLOW MY INSTRUCTION EXACTLY."

Whoa!  Like I needed to know any of that and like anyone needs to be yelled
at over the airwaves with an attitude.  This controller was a young military
male for what any of that is worth.

Granted I heard him wrong and I made a mistake.  But I think the controller
needs to take some responsibility for using confusing verbiage and surely it
was unprofessional to lay me out like that.  This reminds me of how a
mid-air occurred in LA because a new controller took time to admonish a GA
pilot for a couple minutes while a commercial plane and a Piper collided
right in front of him on his screen.

So my question to Steve McNicoll is...is that standard verbiage to say,
"...direct Smyrna 'unable'??.  'cause I'm here to tell ya that, that can be
EASILY confused with 'direct Smyrna 'when able'.  What's your thoughts on
this and did he use proper language or did he just use poor phraseology?

I'll leave the comments about your handling to others, but your
characterization of that 1986 tragedy over Cerritos, CA is grossly
misleading.

The NTSB found no fault with the controller working those aircraft.  In
fact, he is a highly regarded airspace manager today.

The Piper pilot was illegally within the TCA (Class B airspace).

Hello Sam,

I did not mean to be misleading and of course I don't have all the facts.
Using only the information I do have, I feel it a fact that he spent
needless time lecturing a GA pilot who was also illegally in the TCA.  It
would not be a stretch to infer that this distracted him from his scope.  No
one can say that it's not *possible* or even likely that if he didn't give
his lecture that he may have seen the conflict and warned the airliner about
the VFR target's position and direction of flight with the typical "altitude
known".

Hey, who knows, but I am surprised yet happy that this person came back to
the FAA and ATC.  The show *Air Emergency* (which is how I learned about
this) made it appear that once he came back to work, he immediately decided
that ATC was not for him and he never worked for ATC again.  I'm happy
everything worked out for him.  I felt really bad for him when I saw the
show.

If this is the one, I see no mention of ATC distraction:

You should read the full NTSB report.  I found it on-line this morning
with a Google search:

http://amelia.db.erau.edu/reports/ntsb/aar/AAR87-07.pdf

The Piper's primary target didn't show because of a weather inversion.
Because he was sqawking 1200 his beacon return was rudimentary (which
the NTSB did find fault with).

The other aircraft that violated the TCA was being worked by the
controller.  When he determined (no mandatory Mode C at the time) that
the aircraft was inside the TCA without a clearance the controller made
it clear that he was inside the airspace and that he needed to use his
TCA chart more dilgently. It was an appropriate response to the
intrustion; not a tirade.

Traffic was light for LAX airspace, and there were two controllers on
this position.  Had they both had their eyes glued on the DC-9 they
still couldn't have detected a potential mid-air in the making.  The
technology at the time was just too crappy.

Had you read back the instructions, the chances of any confusion would have
been greatly reduced.  You should always read things back.

If you read back "when able" after he says "unable," he'll probably catch it
and correct you.  If you don't read anything back, you never know.
Viperdoc - 07 Aug 2008 17:51 GMT
Anthony, where do you get off telling a real IFR rated pilot about how he
should read back instructions, when you have never been at the controls of
anything other than a computer game? Do you even remotely think that talking
with play controllers in any way mimics the real IFR environment?

Get a clue- you don't know anything about flying IFR or in IMC.
Kobra - 07 Aug 2008 20:07 GMT
> Where was your readback?

I read it back and just like me he heard what his brain expected to hear:
'unable' when I actually said 'when able' .  I wish I thought of that while
I was being reprimanded.  I was just too busy flying, being embarrassed and
head scratching trying to figure out how this whole misunderstanding took
place.

But as I said before, the big issue with me was the way he snapped.  I just
think he was a young man, given a little authority, probably a junior
trainee controller sitting with him, I'm in charge and fear me attitude and
probably having a bad day.

I seem to recall that ATC isn't responsible for not correcting
mis-heard readbacks so don't count on that, ever.  Now, were it me:

1) File an ASRS form, now.

2) WRT the instruction, I would have thought the prefered method would
have been "<aircraft>, unable Smyrna."  As you mention, "Smyrna
unable" is confusing.  In fact, if I read the 7110.65 right, he wasn't
in compliance with the approved terminology in 2-1-18(c):

2-1-18: Operational requests
c. State the word “UNABLE” and, time permitting,
a reason.
PHRASEOLOGY-
UNABLE (requested operation).
and when necessary,
(reason and/or additional instructions.)

3) Never get into an on-air discussion.  Just shush and go on to the
next sector.  It's not worth the airtime, regardless of what the guy
on the ground is doing.  You have better things to be doing, like
flying the aircraft.  If you want to get into it later after you
landed, ask for the controller's initials, note the time, and then
call his facility and ask for the supervisor or QA guy.  They'll take
the information and pull the tapes.
Steven P. McNicoll - 07 Aug 2008 21:43 GMT

Not so.  Controllers are still responsible to insure readbacks are correct.
That was never changed and never even proposed to be changed.  It was widely
misreported.

Order JO 7110.65S Air Traffic Control

Chapter 2. General Control

Section 4. Radio and Interphone Communications

2-4-3. PILOT ACKNOWLEDGMENT/READ BACK

a. When issuing clearances or instructions ensure acknowledgment by the
pilot.

NOTE-
Pilots may acknowledge clearances, instructions, or other information by
using "Wilco," "Roger," "Affirmative," or other words or remarks.

REFERENCE-
AIM, Para 4-2-3, Contact Procedures.

b. If altitude, heading, or other items are read back by the pilot, ensure
the read back is correct. If incorrect or incomplete, make corrections as
appropriate.

Hm, OK, thanks.  What I seem to remember is someone who got violated
for doing something that they read back incorrectly and used "but the
controller didn't fix the readback" as part of the defense and still
had the violation upheld as it wasn't ATC's issue if they didn't
correct an incorrect readback.  Wouldn't be the first time I
misremembered somethin tho.

It happened a little differently.

Aircraft A requested a different altitude.  ATC assigns different altitude
to aircraft A.  Aircraft A and aircraft B read back altitude issued to
aircraft A.  Controller hears only loud squeal, asks aircraft A to say
again.  Loss of separation occurs between aircraft B and aircraft C.
Aircraft B is violated for taking a clearance issued to another aircraft.
Aircraft B's defense is the uncorrected readback, a readback that was never
heard or acknowledged by ATC because it was blocked by aircraft A's
readback.

I read an ALJ's decision where a pilot got violated even though his readback
error was not caught.  The controller was charged with an error as well.
This is no doubt the exception as usually the controller buys the error
exclusively.

Speaking of questionable phraseology.

Who is "violating" all these pilots.

And what is the manner in which they are "violated".

sounds painful

If ATC isn't supposed to correct an incorrect readback, why have readbacks?
Or is that not what you mean?

If he reacts that emotionally to something this trivial, perhaps air traffic
control is not the best career choice for him.  Angry young males make poor
air traffic controllers (in fact, they are bad at just about everything except
perhaps bar fights).

Yeah, he got the phraseology bass-ackward.

Yeah, he gave you a ration you probably didn't have coming.

Maybe he was having a bad day.  Maybe he just got told he's going to the
sandbox for another 13 months; for his second or third time.  Maybe he was a
trainee trying to impress his trainer with his "control."  Maybe a lot of
things.

If anyone else in the facility heard the exchange he's likely already gotten
some wall-to-wall counseling.

sh.t happens :-/  Be the adult and drive on.

Bad phraseology on the part of the controller.  When denying a pilot's
request the transmission is supposed to begin with "unable".  When approving
a pilot's request it's supposed to end with "approved" or just "approved as
requested".

Order JO 7110.65S Air Traffic Control

Chapter 2. General Control

Section 1. General

2-1-18. OPERATIONAL REQUESTS

Respond to a request from another controller, a pilot or vehicle operator by
one of the following verbal means:

a. Restate the request in complete or abbreviated terms followed by the word
"APPROVED." The phraseology "APPROVED AS REQUESTED" may be
substituted in lieu of a lengthy readback.

PHRASEOLOGY-

(Requested operation) APPROVED.

or

APPROVED AS REQUESTED.

b. State restrictions followed by the word

"APPROVED."

PHRASEOLOGY-

(Restriction and/or additional instructions, requested operation) APPROVED.

c. State the word "UNABLE" and, time permitting, a reason.

PHRASEOLOGY-

UNABLE

(requested operation).

and when necessary,

(reason and/or additional instructions.)

d. State the words "STAND BY."

NOTE-

"STAND BY" is not an approval or denial. The controller acknowledges the
request and will respond at a later time.

The usual way to say this is "unable direct" or "unable direct Smyrna".

Your readback of the whole instruction should have tipped him off, since there
was no real reason to read back what he basically read back to you, but
with "unable" at the front.

I have had several controllers go off on me like that, and even went through
the motions of complaining, getting the tape read back, etc.

Why waste your time and energy. There was a misunderstanding. It wasn't
personal. In 5 minutes you will be talking to someone else, and if it is
*really* bad (a voilation), you don't want to be recorded as being
belligerent.
