a Calculated Take-Off Time (CTOT) that the Aircraft Operator should comply with and a time window around the CTOT in which the aircraft has to take-off. This time window is used for sequencing departure flights

Valdkond ICAO lisade põhjal loodud klassifikaatori järgi: Lennuliikluse korraldamine
Staatus: kinnitatud
Tegemist on lennuliiklusest tuleneva piiranguga stardiajale (stardivahemik -5 kuni +10 minutit), mis võib tekkida lähtelennuväljalt, sihtlennuväljalt või kasutatavast õhuruumist ning mille eesmärk on hajutada õhusõidukite saabumist.
Demand is managed by giving the aircraft a slot stating when it can take-off – the ‘Calculated Time of Take Off’ or CTOT. Normally, the aircraft should take-off within 15 minutes of the time stated in its flight plan but, if a slot is necessary, then this window is shrunk – to within five minutes before the CTOT or within ten minutes after the CTOT. If the aircraft can’t achieve this take-off time, then it has to reapply for a slot.
The air traffic control (ATC) slot is needed by each ATC regulated departing flight on the actual day of operation to avoid congested airways. This slot is only valid for this specific flight and for a specific departure time window of 15 min.
