Simplified CDM Procedures (APP/CTR)

Starting CDM (All Controllers)

AsOnly one controller per airport can be CDM master, and only the firstmaster thingcalculates whenTSATs. The master shall be the lowest online position at that airport (DEL > GND > TWR > APP/CTR top-down). All other controllers are slaves by default and do not need to do anything.

2. Once there areis no master controllers,master, the new controllescontroller getstakes the master "role"over by writing .cdm master BIKFICAO

Never have two masters for the same airport. Coordinate the handover before typing the command.

Simplified CDM Procedures (Top-down by APP/CTR)

This part of CDM is known as the ATFCMATFCM.

Simplified CDM procedures are done from the departure list. Please knownote that:

• You are completely allowed to performuse expanded CDM procedures if your capacity allows
• You MUST adhere to the displayed CTOT for takeofftake-off
• You may ignore TSATs for flights without CTOTs,a CTOT if workload is too heavy.heavy

ifIf a CTOT is present:

• Adhere to TSATthe Displayeddisplayed .TSAT. If the TSAT is not yet within startupthe start-up window (Lightlight green), the pilot must wait.
• When the TSAT is within startupthe start-up window (Darkdark Greengreen), (+/- 5 5min)min), Start-start-up can be approved.

ifIf no CTOT is presentpresent:

• StartStart-up and pushpushback can be approved,approved regardless of TSAT time(simplified procedures only).
• Be aware that non-adherance toignoring TSATs may resultlead into longer waiting times at the runway.
