OTBD AD 2.23 ADDITIONAL INFORMATION

1 Visual docking guidance system (VDGS)

1.1 General safety measures

1.1.1 The VDGS has a built-in error detection program to inform the aircraft pilot of impending dangers during the docking procedure. If the pilot is unsure of the information being shown on the VDGS display unit, he / she must immediately stop the aircraft and obtain further information for clearance.

1.1.2 The pilot shall not enter the stand area, unless the docking system first is showing the vertical running arrows.

1.1.3 The pilot shall not enter the stand area, unless the aircraft type displayed is equal to the approaching aircraft.

1.1.4 When using the docking system, pilots are advised to taxi into the aircraft stand at minimum speed. The system will display "SLOW DOWN" to inform the pilot if the aircraft‘s taxiing speed is too fast. (See ITEM 1.2.6 of Docking Procedures)

1.1.5 To avoid overshooting, pilots are advised to approach the stop position slowly and observe the closing rate information displayed. Pilots should stop the aircraft immediately when seeing the "STOP" display or when given the "STOP" sign by the aircraft marshaller.

1.1.6 THE SBU MESSAGE - The message STOP SBU means that docking has been interrupted and has to be resumed only by manual guidance. Do not try to resume docking without manual guidance.

1.2 Stand docking procedures

1.2.1 START-OF-DOCKING The system is activated by pressing one of the aircraft type buttons on the operator panel. When the system has been activated, 'WAIT' will be displayed.
1.2.2 CAPTURE The yellow scrolling arrows indicate that the system is activated and in capture mode, searching for an approaching aircraft. It shall be checked that the correct aircraft type is displayed. The lead-in line shall be followed. The pilot must not enter the parking stand area unless the yellow scrolling arrows are displayed.
1.2.3 TRACKING On successful capture of the aircraft, the yellow scrolling arrows are replaced by the yellow centre line indicator (Closing Rate Bar). The flashing red arrow indicates the direction the aircraft should turn. The vertical yellow arrow shows position in relation to the centre line. This indicator gives the correct position and azimuth guidance. In the figure, the yellow arrow indicates an aircraft to the left of the centre line and the red flashing arrow indicates the direction to steer in-order to align the aircraft with the centre line.
1.2.4 CLOSING RATE Display of digital countdown starts when the aircraft is 20 meters from stop position. When the aircraft is less than 12 meters from the stop-position, the closing rate is indicated by turning off one row of the centre line symbol per half a metre of the distance, covered by the aircraft towards the stop-position of the stand. The picture illustrates the aircraft is 10 metres from the stop-position, slightly left of the centre line. The red arrow indicates the direction to steer.
1.2.5 ALIGNED TO CENTRE The absence of any direction arrow indicates the aircraft is on the centre line. The picture illustrates that the aircraft is 8 meters from the stop-position and is on the centre line.
1.2.6 SLOW DOWN If the aircraft is approaching faster than the accepted speed, the system will show 'SLOW DOWN' as a warning to the pilot.
1.2.7 STOP-POSITION REACHED When the correct stop-position is reached, the display will show 'STOP' and red lights will be lit.
1.2.8 DOCKING COMPLETED When the aircraft has parked, 'OK' will be displayed.
1.2.9 OVERSHOOT If the aircraft has overshot the stop-position, 'TOO FAR' will be displayed.
1.2.10 STOP SHORT If the aircraft is found standing still but has not reached the intended stop-position, the message 'STOP OK' will be shown after a while.
1.2.11 WAIT If some object is blocking the view toward the approaching aircraft or the detected aircraft is lost during docking close to STOP, the display will show 'WAIT'. The docking will continue as soon as the blocking object has disappeared or the system detects the aircraft again. The pilot must not proceed further, unless the ‘WAIT’ message has been superseded by the closing rate bar.
1.2.12 SLOW This display can be shown for two reasons: BAD WEATHER CONDITION During heavy sandstorm, fog or rain, the visibility for the docking system can be reduced. When the system is activated and in capture mode, the display will disable the yellow scrolling arrows and display 'SLOW' and the aircraft type. As soon as the system detects the approaching aircraft, the closing rate bar will appear. If the system has been configured in this mode to make a shortened ID verification (check of engine position excluded), the aircraft symbol will blink to give attention. AIRCRAFT LOST DURING DOCKING If the aircraft is lost during docking at a distance greater than STOP plus the distance between nose and engine, the display will show 'SLOW'. As soon as the system detects the approaching aircraft, the closing-rate bar will appear. The pilot must not proceed further, unless the closing rate bar is shown.
1.2.13 AIRCRAFT VERIFICATION FAILURE During entry into the stand, the aircraft geometry is being checked. If, for any reason, aircraft verification is not made 12 meters before the stop-position, the display will first show 'WAIT' and make a second verification check. If this fails, 'STOP' and 'ID FAIL' will be displayed. The text will be alternating on the upper two rows of the display. The pilot must not proceed further without manual guidance, unless the ‘WAIT’ message has been superseded by the closing rate bar.
1.2.14 GATE BLOCKED If an object is found blocking the view from the docking system to the planned stop position for the aircraft, the docking procedure will be halted with a 'WAIT' and 'GATE BLOC' message. The docking procedure will resume as soon as the blocking object has been removed. The pilot must not proceed further without manual guidance, unless the ‘WAIT’ message has been superseded by the closing rate bar.
1.2.15 VIEW BLOCKED If the view towards the approaching aircraft is hindered, for instance by dirt on the window, the docking system will report a view blocked condition, i.e. ‘VIEW BLOC’. Once the system is able to see the aircraft through the dirt, the message will be replaced by closing rate bar. The pilot must not proceed further without manual guidance, unless the ‘WAIT’ message has been superseded by the closing rate bar.
1.2.16 SBU-STOP Any unrecoverable error during the docking procedure will generate a SBU (Safety Back Up) condition. The display will show red stop-bar and 'STOP SBU' message. A manual backup procedure will be used for docking guidance.
1.2.17 TOO FAST If the aircraft approaches with a speed higher than the docking system can handle, the message 'STOP' (with red squares) and 'TOO FAST' will be displayed. The docking system will be re-started or the docking procedure completed by manual guidance.
1.2.18 EMERGENCY STOP Pilots should stop the aircraft immediately when 'STOP' is displayed.
1.2.19 CHOCKS ON 'CHOC ON' will be displayed, when the ground staff has put the chocks in front of the nose wheel and pressed the "chocks on" button on the operator panel.
1.2.20 ERROR If a system error occurs, the message 'ERR' will be displayed.
1.2.21 SYSTEM BREAKDOWN In case of a severe system failure, the display will go black except for the red stop indicator. A manual backup procedure will be used for docking guidance.
1.2.22 POWER FAILURE In case of a power failure, the display will be completely black. A manual backup procedure will be used for docking guidance.
