5. STAND ADJACENCY RULES
Standalone Safedock operations can be enhanced with a Superior System to further
improve safety and efficiency.
Safedock units connected in a Superior System network with adjacent gate status
provide:

Overall status for connected gates.

Information based upon aircraft already parked or actively scheduled and
awaiting to be parked at adjacent gates.

An awareness of specific aircraft types parked at each gate compared to
adjacent gates.

Adjacent gate information and rules determine if each Safedock can park a
selected aircraft type at the target gate.

Rules/decisions for Safedock operation.
Superior System manages gate adjacency rules with an Interlock function.
Superior System Interlock function Image examples
(a) Gate layout outline
FIGURE 3.22 - GATE LAYOUT
The example is for aircraft types allowed to park at a gate:
Stand Left Right
Aircraft type Any Narrow bodied
Aircraft type None (Blocked) Wide bodied
If a wide bodied aircraft is docked to the right and airport
personnel request to start a docking to the left for any aircraft,
the Superior System generates an adjacency conflict and
messages block the request in workstation and Operator
Panel views.
(b) Superior System workstation view
FIGURE 3.23 - SUPERIOR SYSTEM WS
VIEW
A docking request is started when airport personnel select an
aircraft type, either from a Superior System workstation or
locally from an operator panel. The Superior System then
performs an interlock evaluation for the aircraft type, the
status of adjacent stands and decides if a docking is to be
allowed or not (
Blocked ).
The interlock evaluation is based on a series of blocking
rules, which are configured for each stand. As a docking
request is started, all the rules for the stand are evaluated,
and the request is allowed or denied accordingly. If Superior
System is unavailable as a docking request starts, Safedock
asks the local operator for a manual confirmation to start the
docking procedure. If no rules are specified for the selected
stand, the docking is always allowed.
