The second set of procedures would be those agreed through ICAO. It is interesting, as always, to find out where these might differ from local (here, French) rules.

LFOK Chart Looking at the chart, 2 interesting things:
- If you overfly KELON at FL80, then you're up (or down as you wish
) for some turns before you reach the compulsory 2500ft at the IF. Or you have good S/B... So what is the point in clearing for approach as early prior to KELON as Spud3 describes?
- Entry protection of hold at KELON is 5000ft pressure altitude. So if you start holding at FL80 you may end up in an other airspace, so I'm pretty sure standard local instructions are to clear at least down to 5000ft if holds are expected.
I'd say the ATCO might have been a bit lazy, from what I can picture from the situation, I would have cleared the ACFT down to 5000ft in the same message as the approach clearance, in order to clear any ambiguities...(here 2500 would have even been ok, I think the minimum radar altitudes in the area are lower than that even 25NM away from CAV)
