Phraseology to Stop Take Off

[fireflybob]

I was interested to know the RT Phraseology in the UK should ATC need an a/c to stop take off after take off roll has commenced?

[iainfs]

"BAW123, stop immediately; I say again BAW123, stop immediately -- acknowledge"

[BOAC]

I believe it to be
"FFB1 stop immediately, I say again stop immediately, acknowledge"

[Spitoon]

UK phraseology

If the aircraft has not commenced take-off.
(A/c identity) hold position, Cancel take-off – I say again cancel takeoff – acknowledge.

If it is rolling
(A/c identity) stop immediately – I say again (a/c identity) stop immediately – acknowledge. Aircraft commenced take-off.

There was a lot of very valuable guidance to controllers on the topic in ATSIN 68 - long withdrawn and gone from the web site. It seemed to me that only a fraction of the info went into other documents when the ATSIN was withdrawn.

Thanks for the information - I thought that was the case.

On the thread reference an alleged runway incursion at JFK, I noted ATC used the phrase "Cancel take off" - is there an ICAO phraseology?

[Spitoon]

ICAO is slightly different.

G-CD HOLD POSITION, CANCEL TAKE-OFF I SAY AGAIN CANCEL TAKE-OFF VEHICLE ON RUNWAY

and

FASTAIR 345 STOP IMMEDIATELY FASTAIR 345 STOP IMMEDIATELY

are the examples in the Manual of Radiotelephony.

And there you have it, straight from the broom cupboard monkey's mouth.:p

Ginger Nuts!

[Spitoon]

Huh? Too much of Thatcher's local speciality? Or am I missing something obvious, Standard?

[ZOOKER]

Only ever did this once.
It was a SAS MD80 and it was "SAS*** STOP, STOP, I say again STOP...acknowledge".

In the U.S. it is A/C Callsign "Cancel Takeoff Clearance (and reason if time)" As with everything in the U.S. I'm sure it evolved out of some sort of litigation.

[BOAC]

As with everything litigious, while an aircraft should not be expected to stop on this call above V1, should it have a 'nasty' stopping on an ATC call there is ample room for the lawyer sharks to circle. The US method (not using the word 'STOP') is actually safer, although a bit more cumbersome.

[FRQ Charlie Bravo]

Australian AIP GEN 3.4 5.14.6.4:

Take-off Clearance Cancellation:

ATC: (aircraft call-sign) HOLD POSITION, CANCEL, I SAY AGAIN CANCEL TAKE-OFF (reasons)

Pilot: HOLDING (aircraft call-sign)

to stop a take-off in emergency conditions note: Used only when an aircraft is in imminent danger:

ATC: (aircraft call-sign) STOP IMMEDIATELY (repeat aircraft call-sign) STOP IMMEDIATELY (reason).

Pilot: STOPPING RUNWAY (number) (aircraft call-sign)
(my addition of the unwritten and assumed parts i.e. "(aircraft call-sign)")

The second one seems a pretty gutsy call to me. ATC of course don't have access to a particular flights V1 or ASI so I'd have to say that the ambiguity involved in the US terminology is less distracting to an aircrew although it is possible that it lacks the feeling of urgency that the word STOP invokes. I suppose that the tone of the controller's voice and any amplifying reasons stated will correct for this however.

Has anybody here experienced this in the sim? Seems like a good one to mix things up a bit (and catch somebody like me off guard).

It works in the real world. I've been 'stopped', ("Stop immediately..." is the phrase in the UK). Light aircraft on a parallel taxiway instructed to park on the grass turned onto the grass and then kept coming at a good speed towards us on the runway.

[Lon More]

Never worked TWR but once had a trainee scream "Stop" at a 747 at FL290.

He decided a career in management might be a better option.:*


(He hadn't realised I'd seen that he had lost it completely and had quietly unplugged him and resolved the conflict)

[dagowly]

As per CAP 413

"G-CD, hold position, cancel take-off
I say again cancel take-off,
acknowledge"

[reportyourlevel]

As per CAP 413

"G-CD, hold position, cancel take-off
I say again cancel take-off,
acknowledge"


You need to re-read either the OP or the book!

[dagowly]

That's what the controlled copy of 413 says about cancelling take off clearance, chapter 4, page 9 and as the OP wanted to know the info... Well...there you go.

I prefer the miltary way. Callsign hold.

[Andy Mayes]

dagowly, as reportyourlevel says, you need to re-read the OP for the phraseology you have given is what is given before an aircraft has commenced its takeoff run. This is different to what is asked for in the OP, Civil Aerodrome ATCOs (in the UK) are well aware of the differences and I personally have been asked the for the different phraseology on every competency check in the last 3 or 4 years.

[reportyourlevel]

As AndyMayes says, the difference is important. Also, when it comes to ATC procedures you may as well chuck the 413 in the bin. 493 is where it's at.

[Spitoon]

I prefer the miltary way. Callsign hold.We're all entitled to our preferences but the published procedures are what matters, then everyone knows what to expect.

It's good to look at the big picture too. In the civil world with multi-crewed aircraft, flightdeck procedures to abandon a take-off in many carriers is to call "Stop". When the ATC phraseology was reviewed it was important to avoid questions about whether the other pilot or ATC was the person who just shouted "Stop" at a time when things need to be done quickly. Sometimes there are good reasons for things being the way they are, even if we don't necessarily like the procedures.
