applying wake separation
Been having a discussion about how, exactly, Tower applies the 2 or 3 minutes wake separation and where is this laid down in docs?.
Seems some airports use a stop-watch to measure time from rotation until next is cleared for take-off.
This also brought us onto how times are recorded and where this is laid down.
Sounds like Europe record to the nearest minute but ICAO used to say the current minute.
Any deffinative answers appreciated.
