7. AIRCRAFT SAFETY CHECK
The Safedock system includes the Aircraft Safety Check feature, which is a further
enhancement of its safety performance. Aircraft geometry is analysed by means of a
true 3D measuring technique, thus bringing safety risk to a minimum.
When a particular aircraft type has been assigned with the start-of-docking command,
and another type of aircraft is approaching the stand in reality, there is a risk for a
collision with fixed ground equipment, the Passenger Boarding Bridge or the terminal
building. However, several mistakes should have been made before such an accident
would occur:

the correct type of aircraft has not been assigned by the operator

the pilot has not discovered that an incorrect aircraft type is displayed on the
docking system

the incoming aircraft geometry differs from the assigned one in a negative and
dangerous way
With
the Aircraft Safety Check feature the approaching aircraft’s geometry is analysed
and compared to parameters of the aircraft type that was assigned with the start-of-
docking command.
If the aircraft geometry has not been verified within 15 metres from the stop-position,
the Pilot Display will show
STOP/ID FAIL .
As the requirements for permitting the aircraft to enter the stand are more restricted by
a Safedock system using this feature, the
STOP/ID FAIL message may be shown
also if the aircraft is approaching diagonally or too fast.
7.1 EXTENDED ID FAIL LIMIT
Each aircraft can individually be configured to use an extended ID Fail limit of up to 25
metres to the stop-position. This option is described in more details in Chapter 4A
Stand Configuration Utility § 4.7.1.
