European verbiage
Question,
Flying in Europe, when ATC says, "fly heading 123 intercept ILS 27" does that clear one for the full ILS approach?
Thank you in advance!

I assume you may have been flying in the UK? (I say this because most countries seem to just use "cleared ILS approach").
If so the answer is no, but there are a few different options available to ATC.
"BAW123 turn left heading 290 degrees, intercept the localiser runway 26", this instructs you to turn to the heading and intercept the localiser. It is NOT an approach clearance.
"BAW123 turn left heading 290 degrees, when established on the localiser descend on the glidepath", this instructs you to turn, intercept LOC and descend on the glidepath, from your current cleared level.
"BAW123 turn left heading 290 degrees, cleared ILS approach runway 26"
This is the same as above, however, as it's been explained to me,under ICAO standards the phrase "cleared ILS approach" means that you may descend to the level published on the approach chart, regardless of your previously cleared level. In the UK this was considered dangerous (as many a times the charted level can't be used for separation purposes), therefore the phrase "cleared ILS approach" is only to be used when you are already cleared to, or lower than, the charted approach level (and up until not long ago, it wasn't used at all).
Hopefully that makes sense.
The phrase "intercept ILS" is (as far as I know anyway) not in the RT manual (CAP413), so if given that I would suggest you clarify if you may descend on the glidepath or not.

A very good succinct reply crazy voyager. Just shows how confusing this different phraseology is for the flight deck.
'Cleared Approach" should be used by all, and here in the UK us controllers can monitor the descent of the aircraft. I do it now? It makes things so much easier.

"Intercept and follow localizer RWY..." instead of "cleared ILS approach RWY..." can be used if we have opposite departures and want them "out of the way" before we give the approaching aircraft further descend.
Often, we at least, add "Intercept and follow LLZ RWY... maintain X feet" just to be dead sure they don't misunderstand the instruction.

Nimmer,
Most people here seem to use "cleared ILS approach" now, the only excpetion really being some straight in approaches that can descend on the glide but not to the platform level due to various constraints.
Otherwise the obvious example seems to be Heathrow 27s, where traffic often intercept at 4000 feet (due to City departures climbing to 3000 below) but the platform level I believe (without checking) is 2000 feet.
Then again, if you work in TC you will already know this much better than myself.
Also as a side-fact, I recently flew on a fam flight where we were told to "report established on the localiser". When we captured the PF stated localiser alive, cleared approach? And the PNF said, "yes, cleared approach". Despite the fact that they actually were not allowed to descend on the glidepath.
This was a UK crew operating into their home base in the UK and everyone was a naitive english speaker. It does show how a subtle difference can make a lot of difference.

I often heard "intercept ILS" from ATC at CDG...

No I don't have a reference, I work in the UK where that way of using "cleared approach" isn't authorised as you have to be at or below the platform level. However I've been explained the reason for this is as stated above, that under ICAO you are allowed to descend to the platform level when "cleared approach".
Hopefully someone who actually works in ICAO land will have a reference to it though, I shall ask around and see what I can come up with.

If just "Heading nnn" was given the heading should be continued until authorised to resume own navigation. "Intercept / Cleared ILS nn" qualifies the heading.

CDG is an odd one, many controllers still use "Intercept ILS" or "Intercept full ILS" and sometimes even "Cleared Final Approach" as an approach clearance. I believe this might have something to do with the fact you've been technically cleared for the approach already "Cleared BANOX1W approach radar ILS runway so-and-so" but I have never been able to find out.
