(b) Bridge In Position
(c) Alarm Signal

8.1
DEAD MAN’S GRIP
The Safedock
system can be equipped to use a ‘dead man’ grip function. This
function forces the operator of the Safedock system to keep a switch depressed
throughout the docking process, when the aircraft is present. If the ‘dead man’ switch
is deactivated at any time during the docking procedure, and the aircraft is present,
the docking will be aborted, displaying
ABORTING/DEADMANS GRIP RELEASED
on the Operator Panel and STOP on the Pilot Display, as if the operator had activated
the “OFF” key.
Once the aircraft has reached the stop-
position, the operator can release the ‘dead
man’ switch without affecting the operation of the system. If the ‘dead man’ grip is
released before the aircraft appears at the stand, Safedock will display
WAIT until the
‘dead man’ grip is pressed again.
8.2 STAND EQUIPMENT INTERLOCK
The Safedock system can be configured to require confirmation from relevant stand
equipment such as PBB, fuel pits etc. in order to prevent hazardous situations. If any
equipment is found to be in the incorrect position, the message
Stand Equipment
Interlock will be displayed on the Operator Panel and a warning message on the Pilot
Display. The confirmation can be enabled per aircraft type at the stand. The
equipment interlock logic is configurable per aircraft type, allowing for any combination
of bridge settings at a single stand.
8.3 ALARM SIGNAL
The Safedock system can be equipped with a potential free alarm output for
connection to an external alarm system. The alarm output will be activated on any
error detected by the Safedock system. Alternatively, a Superior System can be used
to collect error messages from the Safedock systems and forward them to a central
alarm handling system.
8.4 DOCKING IN PROGRESS SIGNAL
The Safedock Operator Panel is equipped with a potential free output used to indicate
that a docking procedure is i
n progress. A “docking in progress” signal can be used by
external systems
when there’s a need to know that a docking procedure is activated.
(a) A li
ght control system can use the “docking in progress” signal to
automatically activate the lead-in lights at the stand when a docking
procedure is activated.
(b) The bridge control system can
use the “docking in progress” signal to inhibit
any outward movement of the bridge during a docking procedure.
8.5 PUSHBACK DATA TRANSMISSION
The Safedock system can be equipped with a feature to track an aircraft during the
pushback procedure. The distance information gathered during pushback is forwarded
