Full Supervision (FS)
FS-[L123].1The Full Supervision (FS) mode is the mode with which a complete supervision of the train is achieved. The ETCS on-board equipment is fully responsible for the train protection in this mode.
The FS mode cannot be selected by the driver. It is entered automatically when all necessary conditions are fulfilled.
FS.RUNRunning in FS (RUN)
FS.RUN-[L123].1When the FS mode is entered, the Full Supervision symbol (MO11) is displayed:

MO11: Full Supervision
In this mode, the driver shall not exceed the permitted speed.
The driver is only responsible for:
- Respecting the EOA when approaching an EOA with a release speed.
- Respecting speed restrictions that are not covered, when message “Entering FS” is displayed.
FS.RUN-[L1.T].1The DMI appearance when the FS mode is active is included in Figure FS.RUN-[L1.T].F1:

FS.RUN-[L123].2If in addition to the FS mode symbol (MO11) the following text message “Entering FS” is displayed. The driver shall not exceed the speed restrictions.
FS.RUN-[L123].3The driver is responsible for respecting the EOA when approaching an EOA with a release speed.
If the driver overpasses the EOA/LOA marked on the DMI screen, the train changes to Trip mode, see section TR - Trip / Post Trip (TR). The transition to Trip mode is also triggered when receiving an order from trackside.
FS.RUN-[L123].4Additionally to the transition mentioned previously (i.e. FS → TR), the following mode transitions can be triggered from FS mode:
- NP mode. Transition triggered when the ETCS on-board is powered off, see section OFF.PWR Power off the ETCS on-board (PWR).
- SB mode. Transition triggered when the desk is closed, see section OFF.CLS Close the desk (CLS).
- SH mode. Transition initiated either manually by the Driver, see section SH.MAN Manual entry into SH (MAN), or automatically by an order from the Trackside, see section SH.AUT Automatic entry into SH (AUT).
- LS mode. Transition automatically initiated by an order from the Trackside, see section LS.APP Approaching an LS area (APP).
- SR mode. Transition manually initiated by the Driver when override, see section OVR.RUL Rules to pass an EOA (RUL).
- OS mode. Transition automatically initiated by an order from the Trackside, see section OS.APP Approaching an OS area (APP).
- NL mode. Transition manually initiated by the Driver (see section NL - Non-Leading (NL).
- UN mode. Transition usually initiated by an order from the Trackside, see section UN - Unfitted (UN). This transition also includes a transition to level 0 initiated either manually by the Driver, see section LTR.TRS.DRV Level transition initiated by driver (DRV)) or ordered by the Trackside, see section LTR.TRS Level transitions (TRS).
- SF mode. Automatic transition triggered in case of a fault, see section SF - System Failure (SF).
- IS mode. Transition triggered when the driver isolates the ETCS on-board equipment, see section IS.ENT Entering Isolation mode (ENT).
- SN mode. Transition usually initiated by an order from the Trackside, see section SN - National System (SN). This transition also includes a transition to level NTC either initiated manually by the Driver, see section LTR.TRS.DRV Level transition initiated by driver (DRV) or ordered by the Trackside, see section LTR.TRS Level transitions (TRS).
- RV mode. Transition initiated after the driver“s acknowledgement of the RV mode as indicated in section RV - Reversing (RV).
