CDM phraseology

Standard phraseology for CDM. Replace the times and callsigns with the actual values.

Clearance delivery

Flight has a CTOT

ATC: "ICE123, cleared to Copenhagen via ..., squawk 1234. Slot 1430."

Pilot: "Cleared to Copenhagen ..., squawk 1234, slot 1430, ICE123."

The pilot must read back the slot. Take-off must be between 1425 and 1440 (-5/+10).

Pilot asks about their start-up time

ATC: "ICE123, expect start-up at 1415."

TSAT is dark green (within the window)

ATC: "ICE123, start-up approved."

TSAT is light green (pilot is early)

ATC: "ICE123, expect start-up at 1415, call me back at 1410."

Set ASRT and try Ready TOBT to see if an earlier TSAT is available.

An earlier TSAT becomes available

ATC: "ICE123, start-up approved." (or) "ICE123, new start-up time 1408."

TSAT has expired (blank)

ATC: "ICE123, your start-up time has expired. Update your TOBT on the VDGS, or advise when ready."

If the pilot is ready now, use Ready TOBT and give the new TSAT.

Flight will miss its CTOT

ATC: "ICE123, you will not make your slot. Standby for a new slot."

The CDM server issues a new CTOT once the TOBT is updated.

CTOT has changed

ATC: "ICE123, revised slot 1450."

Taxi or take-off with a CTOT

ATC: "ICE123, taxi to holding point runway 10. Your slot is 1430."

Do not give take-off clearance more than 5 minutes before the CTOT.
