Heard this more than once on London frequencies, the clearance is questioned by the aircraft usually with "confirm unrestricted climb"
and normally receives a rather curt reply from controller.

ICAO are making a real mess of the climb/descend phraseology on SIDS and STARS. Personally I would like to see the same
methodology that is applied to take off clearances, ATC shouldn't even mention the word climb or descend until you are actually able to
do it, conditional climb or descent clearances are not the way we should be going.

So what's the conclusion? If the ATC did not say "Now", it's questionable isn't it?

In ICAO world for SID's there is no:
"CLIMB"
"CLIMB NOW, OPEN CLIMB" (in spite those ones are obvious)

CLIMB VIA SID TO (level), CANCEL LEVEL RESTRICTIONS :mad:

^-- it's one or the other, how can you have both??

Why??
Read more carefully the green squared explanation

​​​​​​​Well it's a contradiction in FAA land where I'm from, where "via" refers to vertical navigation and means specifically to comply with the level restrictions. So under that premise, this phrase is essentially saying "comply with the level restrictions, cancel level restrictions.":confused::{

But after some deduction, the explanation has to be that the premise of the jurisdiction of this document is that "via" refers to lateral navigation. So this would be saying to comply with the lateral navigation, and cancel level restrictions. OK, makes sense. But then it's completely redundant, if they omitted the "climb via" bit then you would have continued on the lateral path you were already cleared to. So what's the point of saying it? It doesn't add any meaningful information and only creates confusion because if you consider that the information must be significant, you're gonna look for some meaning in it that tells you to do something you're not already doing. (This isn't the first time I've had to relearn not to consider that the information must be significant)

In the UK, climb straight away. See the AIC linked in post 9.

Ah, finally I put the effort in to do that... it was quite straight forward.

Now I wonder what all the fuss is about :O

You and me both! That's exactly why I linked it, it really is pretty easy. The discussion if the UK should be different from the rest of ICAO is a separate thing and is worth having, but the current system really isn't complicated once you sit down and read it.

The question is, did you read that AIC before you went to Pommie land? :)

I don't have permission to view it, weird but i found this. Is it the same?

Here

"Within UK airspace, for all stages of flight, instructions to climb or descend cancel any previous restrictions, unless the restrictions
are reiterated as part of that instruction. Additionally, for aircraft on a SID, the word ‘now’ is added to climb clearances above the SID profile,
to highlight that the SID vertical profile is no longer applicable."

It says instructions to climb or descend cancel any previous restrictions (in this case, i'm assuming the restriction at 6000ft), then they went on to say "Additionally"....so if ATC omitted the word "NOW", it still means the level restrictions are cancelled if ATC ask to climb level above the restriction? Vague. So what if ATC omit the word "NOW"?


From Here

"2.2 Pilots flying on a SID in the UK FIRs have been briefed to expect climb instructions that cancel the SID vertical profile to include the word ‘now’. In the absence of this word being used, for instructions to climb above the SID profile, pilots will request clarification from ATC. In some cases omission of ‘now’ has resulted in a delayed climb, and in at least one instance, a deviation from and then return to the vertical profile of the SID, thus generating an increased safety risk, particularly in congested airspace."

MY conclusion: If they omit out the word NOW, I'm going to clarify.

Excellent. I'm glad you got that all sorted! :oh:

Yes absolutely correct and so unfair and dangerous just wondering what is the real reason for all this organizasions for "SAFETY" that we all definenatly concerned, what is the actual reason for established safety regulators ayditirs and the rest if they dont follow the same excact rules for everyone everywhere where can you see the Safety? ICAO EASA, where are we heading aviation people!?
