spreads horizontally as much as 120 degrees and vertically as much as 20 degrees. You can imagine
how much of the airspace is covered by this electronic funnel just a few miles from the runway. This
wide-mouthed funnel is easy to enter because the intercept can be made from any angle and from any
distance within range of the system.
The MLS also has a precision back-course guidance that can help pilots continue to navigate as
they go-around from a poor approach. This guidance provides the pilot reassurance as he reenters the
weather and can no longer see the airport.
Differential GPS Landing Systems. So, what could a very accurate GPS guidance system be
used for by the pilot? How about highly accurate landings? Because GPS signals are not transmitted in
any particular direction, precision approaches can include curved paths and tiered altitudes. In fact, a
GPS approach can take virtually any shape, as it is computer generated.
Approaches have always been a point of discussion with the communities that surround airfields.
Noise and other environmental concerns affect the people in the airport community. GPS approaches
can be molded to the community’s needs and still satisfy the aviator. That is the goal of any good
navigation system.
