ATC controller phraseology

[bluelake]

What is the difference between these two phrases:
#1 "Report procedure turn inbound"
#2 "Report established inbound"

To narrow the discussion, let me say that #1 is in the AIM. Also, I have heard both of these nearly interchangeably when on procedure turns during practice IAP's.

 

[Minuteman]

#2 is used for holding pattern course reversals (or at least doesn't specify which reversal should be used)?

 

[Alchemy]

#1 means call as soon as you start turning toward the final approach course during your procedure turn. By that I mean if you're outbound procedure turn heading is 315, as soon as you begin the 180 degree turn to 135, call in.

#2 means call when you're actually on the final approach course ie. you're on the course that will take you down to MDA on VOR, NDB, or GPS approach or you're on the localizer on a non precision approach

 

[MikeD]

Where I hear them:

#1: Upon completion of a course reversal on a procedure turn (45/180, teardrop, etc) and established inbound when flying a PT, or cleared a full approach on an approach with a PT; you'd report "procedure turn inbound" as requested by ATC.

#2: When being given a radar vector to intercept a final approach course (VOR approach for example), reporting "established inbound" means you have case break on the CDI of the HSI/OBS and thus, established inbound. Normally, you'll receive an intercept heading and altitude to maintain "until established" whereby you'll then be "cleared for the approach".

 

[DE727UPS]

I agree with MikeD on #1. On #2, I'd only ad that it might not be just radar vectors, but also after you've intercepted the final course inbound after a procedue turn.

 

[JAM]

1) PROCEDURE TURN INBOUND- That point of a procedure turn maneuver where course reversal has been completed and an aircraft is established inbound on the intermediate approach segment or final approach course. A report of "procedure turn inbound" is normally used by ATC as a position report for separation purposes. (from the P/CG)
This means not until joining/tracking a course toward the airport (after the PT).

2) "ESTABLISHED INBOUND" - this is not defined, but I think a reasonable person would agree with MikeD. If in doubt, just ask the controller!

ESTABLISHED - To be stable or fixed on a route, route segment, altitude, heading, etc. (AIM Pilot/Controller Glossary)

So, are you "stable or fixed" on the inbound route segment while you are still turning?

Are you stable or fixed if you intercept a final approach course and are still descending?

I consider myself established on the route segment once I have course guidance. Is the aircraft at 1G, not accelerating/decelerating, with absolute zero VSI, and rock steady on a heading +/- 1 degree? Of course not. But I'm on the route segment as far as I'm concerned, and for all practical purposes, am established.

[/ QUOTE ]I do not disagree with you in the least (although I'm not sure of the relevance of climb/descent to an "on-course" definition) . What I am suggesting is that the definition isn't particularly conducive to a precise "these many degrees on or off" analysis, and each pilot has to ask herself the question you answered so eloquently.

Turning inbound on an ILS on a calm day, I might consider myself "established" when the needle has come far enough toward center and my heading agrees enough that my interception is no longer in doubt. On the other hand, intercepting an NDB bearing in a heavy crosswind I might well wait until the equivalent of an on-course heading with the needle deflected no more than 10º.

Other pilots may and probably do it differently.

The relavance of the climb/descent remark was in reference to the definition of a "stable" platform.

I agree, the interpretation of "established" is somewhat vague. For a good gauge of when one would or could consider themselves established, I can easily buy your rules of thumb, just as much as others. Key being, if it's working, then it's effective; if it's not working, correct it. Granted, obvious SA, airmanship, and a little prior planning/anticipation would need to go into it, such as the NDB example assuming one had prior knowlege of the winds aloft at that particular part of sky. But I agree with your point.

 

[cime_sp]

The FAA has never defined "established" but FAR's Explained cites a few legal decisions where established was considered to be less than half-scale deflection. Of course that was just some judges interpretation of it. I have also heard people say that as soon as the needle is alive and no longer full scale deflection that you are established because in the instrument PTS as long as you are not full-scale outside the FAF you are still within tolerances.

Basically use your own judgement.

 

[bluelake]

thanks for all the replies. I am on the run, so need to print this out and read it later.. but quickly, Alchemy, what you said is what I THOUGHT.. but it is not what the AIM says.. that's why I referenced the AIM to narrow this down. But, humbly I must correct myself. I intended to say that "procedure turn inbound" is what is found in the AIM, not "established inbound".

 

[bluelake]

MikeD,

I agree with what you are saying. My only confusion is I have been hearing these phrases interchangeably lately. On practice approaches I have heard both, and lots of these approaches are using procedure turns to inbound. If someone just says, "bluelake, its two different ways of saying ya gotta call once your on the final approach course" then I will be happy.

As a lowly and green CFI-I, I was teaching my IR student that if he heard 'proc turn inbound', then report as alchemy suggests.. but if 'report established' then he should report once established. The AIM proved me wrong hands down...

maybe my problem is that different controllers are using different jargon to get me to call at one place in the approach ????

thanks all!

If I'm flying any sort of procedure turn and am told to report procedure turn inbound, then I'm going to do just that. If the controller wants me to report established on whichever segment he instructs me to, then I'm going to do that too.

I'm sure controllers use many interations of this:

Procedure turn inbound, established inbound, report intercepting the final course, report localizer inbound, etc, etc, etc. BL, do what ATC asks. The terms are actually pretty self explanatory, with the exception of what exactly "established" is being somewhat vague. For this, the general consensus is use good judgement.

 

[Alchemy]

One more thing....my CFII taught me to ALWAYS call "procedure turn inbound" when beginning the 180 degree inbound portion of the procedure turn. He told me to do it all the time on every non radar vector IAP even if ATC doesn't request that I do it.

I haven't really looked for this in the AIM, but the controllers never seem to mind and often they'll say "report established inbound" after I call procedure turn inbound.

[/ QUOTE ]How about a very practical answer. I doubt that ATC gives a hoot if you report in at the beginning or end of the 60 seconds it takes to make a 180 or the 30 seconds that it takes to make a 90° turn.

So, how about sticking with the priority of aviate (keep your attention on the turn when turning), navigate (make sure you are indeed intercepting and not just passing through), and then communicate?

This is not correct. Procedure turn inbound means you have captured the final approach course and are now flying it inbound toward the final approach segment.

#2, report established inbound, would be used for approaches not utilizing a procedure turn.

 

[DE727UPS]

PROCEDURE TURN INBOUND- That point of a procedure turn maneuver where course reversal has been completed and an aircraft is established inbound on the intermediate approach segment or final approach course.

http://www1.faa.gov/ATpubs/PCG/

I always thought it was after the course reversal but before intercepting the inbound. However, this defination from the pilot/controller glossary says it would also be correct to wait until intercepting the final approach course.

 

[bluelake]

Midlifeflyer...
I did those things. I aviated the airplane nice and level, 2000' MSL and 90 KIAS. I navigated.. went outbound, and then did a tidy 180 turn inbound. I got all that. My question is about the communicate.

and to MikeD.. I totally agree with your comment. Theres lots of variants in ATC language. Perhaps its a one way street though.. god help the new pilot who says 'roger' when ATC wants to hear 'affirmative'

thanks to all replies. make no mistake, I aint discontinuing my lessons over this.. just a picky little curiosity .

That's good to know. I'll be sure to "change my ways".
