Good evening,
I am looking for one definition...

< Long Final > when landing (according to ATC phraseology) is between 8 and 4 Nm
< Final > when landing (according to ATC phraseology) is below 4 Nm
What about < Short Final > ? When does it start?I found some information in the CAP 413 - Radiotelephony Manual. But to have flown in Europe, I can remember some States differences.

What about ICAO? I cannot find?
I appreciate any inputs. Thanks in advance
My best regards.

I think it's after the 30 stabilized second.

For me at LHR, short final is about at 300ft without a landing clearance, and I may prompt ATC for that clearance or a 'land after'. LHR is my home base however, and I am used to late landing clearances, sometimes while just about to flare:ooh:. Others not as used to LHR may call 'short final' at 600 ft or 2nm from observation.

Short final is not defined by ICAO, although interestingly the term is used in an example in the ICAO Manual of Radiotelephony. Some States may have defined the term - the UK has not.

It can probably be best summed up in practice as indicating a degree of urgency when used by the pilot (as in 'Well, can I land or not?') or perhaps as a reminder when used by a controller so tht he/she does not have to continually watch an aircraft as it goes around the circuit. I would expect the range that qualifies as short final to vary with the aircraft type/size/speed. For a Boeing or Airbus I would go with TopBunk and say inside 1 mile would commonly be called short final but for a C150 inside half a mile and maybe even coming over the LLZ would not be an uncommon view.

Well the CAP 413 states 'Long final' as being between 8 and 4 miles, so 'final' (no 's'!) must be inside 4 miles.

While not defined, 'short final' I would imagine is at your discretion. I agree with spitoon and Topbunk that it varies, but for an airliner it is a mile or so, which would certainly not always be short final for a C150 in a headwind.

Like Topbunk said, landing clearance can come on very very short final, indeed after decision altitude but that's another can of worms. At my base they often warn to expect a late landing clearance only to issue it so early that you'd never get cleared to land that early at Heathrow unless you were the first to arrive in the morning!
