Developed in conjunction with Gatwick Airport, Mirror Technology
can offer a low cost, fail safe method for the precision parking
of commercial aircraft.
Traditionally marshallers have carried this out; indeed at many
airports this remains the most common method of parking aircraft.
However with increasing pressure on manpower and shorter turn round
times automated systems are now required. Electronic systems are
complex and need sophisticated maintenance procedures. Consequently
various simpler guidance systems have been developed to provide
accurate positional guidance with lower costs and less complexity.
Many such methods are in common use but mirrors have the advantage
of giving the pilot a true view of his nose wheel approaching the
correct stop position.
Maintenance is straightforward with cleaning being required regularly
depending on pollution levels. The only other check is alignment
and this can be automatic. No doubt pilots will be quick to point
out any misalignment! It is worth noting that a mirror system is
failsafe. It cannot give a dangerous image; either the wheel is
visible or not. Some airports have barriers around the mounting
post to help prevent impact damage.
Mirrors provide an excellent method of automatically assisting aircraft
parking. Provided care is taken on the initial installation they
can give many years of low maintenance service. They are especially
suitable for use in airports experiencing expansion with low cost
airlines.
