2.2.3. Flight Update Message (FUM) — data exchange with the CFMU
The CFMU generates and sends flight update messages (FUM) for inbound flights to
Munich Airport. The following operational events trigger the transmission of an FUM:
• Estimated landing time (ELDT) minus 3 hours
• Modification of the ELDT by 5 minutes or more (parameter 5-15 minutes)
• Change to the ETFMS status, e.g. suspension of a flight
The FUM provides an ELDT at an early stage. This allows the system to compare the
inbound with the outbound flight plan, i.e. the EIBT 1 with the EOBT. A comparison is
made between the receipt of the ATC flight plan and the generation of the TOBT (TMO).
In the case of inconsistencies, the contact address of the airline will be informed
accordingly. The airline is expected to react immediately by adjusting either the relevant
times (DLA message) or the outbound flight plan (CNL message or aircraft type change).
2.2.4. Automated target off-block time (TOBT)
At final approach (12 minutes out), the system automatically generates a TOBT. The
earliest possible time for automatic TOBT generation is 75 minutes before TOBT
(provision).
TOBT: Automatically generated point of time, whose supervision and updates are
in the responsibility of the Airline/Handling Agent. TOBT is the time when
all ground handling processes will be finished, the aircraft doors closed
and the boarding bridge removed. At this time the start-up approval could
be received and the push-back/taxi clearance can be given. TOBT is a
reference time used for all ground handling processes except for aircraft
push-back and de-icing. This time is used for coordination purposes, since
it is the best available time.
If the time period between in-block and EOBT is less than the Minimum Ground Time
(MGT), a TOBT with the time value in-block plus MGT is generated. The MGT depends
on the airline, the aircraft type and the destination. Another condition for the primary
automated calculation of a correct TOBT is that the TOBT plus the remaining time (RMT)
are either earlier or the same as the CTOT, otherwise, the TOBT is not generated.
