ln the specialised area of aircraft docking - accuracy is crucial. DuraVision™ answers the need with a technically innovative aircraft docking guidance mirror (ADGM) boasting unique design features. The design of the ADGM allows safe and accurate docking of aircraft up to the Boeing 777 without selective operation. The DuraVision™ ADGM is one of the most cost efficient methods of visual aircraft docking guidance, while still providing maximum safety.

Description of Use
The aircraft's signature and stop point (referenced to the nose wheel)
is painted in reverse on the apron and intersects the centre guidance
line. As the aircraft continues along the centre line the pilot can observe
the nose wheel from the cockpit as it approaches the stop bar. The pilot
identifies the appropriate aircraft signature in the mirror and stops
the aircraft when the nose wheel coincides with this point. This method
is both simple and extremely accurate.
Initial outlay
When compared to other systems the DuraVision ADGM provide significant
savings per gate due to its low relative initial outlay!
Safety
The system allows the pilot added peripheral vision which can reduce collisions,
incursions, downtime and injury
Time Savings
Without selective operation the ADGM can accommodate the self parking
of a variety of aircraft types on one stand, hence reducing time delays
of waiting for ground support staff to dock the aircraft
Low Maintenance
Routine maintenance involves only an occasional clean of the unit, hence
routine maintenance costs are extremely low. Unexpected maintenance costs
are virtually eliminated due to the simplicity and fail safe nature of
the ADGM
Longevity
The mirror is designed to have a life of at least 10 years therefore replacement
costs are minimal
Fail Safe
Due to the inherent nature of the system it effectively cannot fail, therefore
down time caused by the system should be nil
Labour Savings
Because the ADGM allows the pilot to self-park the aircraft ground support
staff can be deployed to other duties
Advantages
Simple and reliable
system preferred by pilots;
Instant visual
feedback of aircraft position;
Accurate,
fail-safe aircraft docking;
Functions
under all lighting conditions equally well in full sun or at night;
Peripheral
vision about the nose wheel and surrounding area for added safety;
Meets ICAO
regulations Annex 14;
Easy to install
and adjust;
Enormous economical
saving over more complex systems;
Low maintenance.
The DuraVision™ ADGM is a simple, fail-safe system that has gained broad acceptance by pilots experienced with the ADGM. Pilots prefer it as it provides instant visual feedback of the aircraft's position without the need for high tech equipment or support from ground crew.
Effective in all flying conditions
Day View
Night View
The DuraVision™ ADGM is effective for all flying conditions. The optional heater prevents the mirror misting or freezing in cold weather and keeps the mirror clear at all times while the natural angle of the ADGM once installed allows rain to run-off. Under ICAO regulations minimum light levels must be maintained around airside structures and the ADGM will operate effectively under all lighting conditions that are appropriate to aircraft movements
Fail-safe and accurate
Unlike highly computerised systems that can fail without warning the risk of failure or malfunction is virtually nil. As long as the mirror provides an image and is adjusted correctly the ADGM will continue to operate. The ADGM provides a fail-safe, ICAO compliant system for docking aircraft and the accuracy necessary for underground power, fuel connections and boarding bridge alignment with the aircraft is assured.
The ADGM high visibility and location on the apron ensures that it is not a safety hazard and will not interfere with ground support equipment and pushback vehicles.
Multiple Aircraft Gates
A single ADGM can accommodate several aircraft types up to the Boeing 777, on one gate with no adjustment necessary between aircraft. Each type of aircraft has the appropriate stopping line printed on the apron.
Simplicity
Installation of the mirror is low cost and simple, requiring a single post mounted on the apron, a power source for the misalignment beacon and optional heater while calibration and adjustment is simple and straightforward.

ICAO Compliance
The Duravision ADGM is compliant with ICAO International Standards and Recommended Practices, Annex 14, Chapter 5.3.22 and all other pertinent standards.
Annex 14 stipulates that during docking a pilot may not move his or her head from the central position. This new regulation (effective 4 November 1999) means that many existing systems (eg. light boxes) in Contracting States to ICAO will be non-compliant on 1 January 2005.
Annex 14 also stipulates that the docking system should
have a clear indicator of malfunction, such as our misalignment beacon.
