I wanted to write 'Any" instead of "ant". Finger or keyboard malfunction.
I know this a subject with great controversy. I have looked from the ICAO Doc4444 to the 8168, the 9426 and 9689 etc. I have visited Skybrary and Forums. I have discussed it with pilots and controllers. So far, I have just a big lot of different answers and opinions. Looking at Forums, there are discussion for years about it. Amazing. Hasn't someoone felt the need to implement a stupid rule. I couldn't find the meaning of a "late landing clearance" neither. It is just made up. I'll keep trying.
Thank you for all inputs and references if you know of any by any chance.
