Starting CDM & handing over master

BeforeEach CDM canairport calculateneeds any TSATs,exactly one controller must be master. forOnly eachthe airport.master Thiscalculates page explains who that is, how to start CDMTSATs and howcan toset handmanual over.CTOTs. Everyone else runs as slave.

Who is master?master

Only one controller per airport can be CDM master, and only the master calculates TSATs. All other controllers are slaves by default and see the master's times.

The master shall be the lowest online position at that airport: DEL > GND > TWR > APP/CTR (top-down).

Online at BIKF	Master for BIKF
BIKF_DEL, BIKF_TWR, BIKF_APP	BIKF_DEL
BIKF_TWR, BIKF_APP	BIKF_TWR
BIKF_APP only (top-down)	BIKF_APP
BICC_FSS only (top-down)	BICC_FSS

Starting CDM

If you are the lowest position online at an airport, write .cdm master ICAO (e.g. .cdm master BIKF) in the EuroScopeairport: commandDEL line.→ GND → TWR → APP/CTR.

• Only BIKF_APP online: BIKF_APP is master.
• Only a BIRD CTR online: the commandCTR onceis master for each airport,CDM e.g.airport .cdmit mastercovers.
BIKF and .cdm master BIRK.

CDM airports in BIRD: BIKF, BIRK, BIAR, BGGH, BGSF,BGSF and EKVG.

Starting CDM

1. Select the active departure runways in the EuroScope runway dialog. With no runway selected, CDM calculates nothing. At BIKF, the runways selected also decide the departure rate.
2. Type .cdm master BIKF (repeat for each airport you cover).
3. Check the CDM airport panel (.cdm panel):
   • Green: you are master.
   • Purple: someone else is master. Coordinate before doing anything.
   • Red: no master.
4. Times update every 10 seconds. If they do not appear, type .cdm refresh.

Handing over master

WhenHand over when a lower position logs on, or thewhen currentyou masterlog logs off, master must be handed over:off.

1. Agree the handover with the other controller.
2. The oldcurrent master switchestypes to slave by writing .cdm slave.
3. Once therethe ispanel shows no master, the new controller writestypes .cdm master ICAOBIKF.

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

If you are master and log off with no onenobody taking over, writetype .cdm slave before disconnecting.

After a EuroScope crash, reconnect, become master again and type .cdm recover BIKF to restore the saved times.
