Evolution of Aircraft Landing Assistance Devices
The most tedious tasks for a pilot to perform are to make a soft landing and to
do it safely. Initially pilots used to land on open fields and used to maneuver
the plane in a direction that gave them a better angle relative to the direction
of the wind. Aides to the landing have been developed to help find the right
course and landing to make sure of the landing.
In the later 1920’s, airports began using lamps, when the landing grounds
were marked by rotating so they can be found after sundown. In early 1930,
airports installed the early forms of approach lights. Both projects have
demonstrated the proper angles of descent, and if the pilots hit the targets.
Their approach paths were drawn to the glide path or glide. Air Mail Service
intermediary, landing grounds that were established near the route used electric
rotating lights and beacons that have been placed on the outside of the field.
Instrument Landing Systems (ILS) used the best features of both radio beacons
and approach lights with a higher frequency of the transmissions. The tests of
these systems began, and the Civil Aeronautics Administrations (CAA) has
authorized the installation of this system in six locations.
Nine CAA operating systems and 10 other sites were being constructed in 1945. 50
others were being built. The American Army has submitted an ILS with a higher
frequencies to reduce the static and more right to set up courses, called Army
Air Force System instrument approach Signal Set fifty-one. The Organization of
International Civil Aviation (ICAO) adopted this standard for the army to all
member countries in 1949. In the 1960's, the first of the ILS equipment for
landing totally blind became available.
The development radars during the Second World War, led to developing a new beam
precision landing aids approach. In 1948, a distance measuring equipment (DME)
is used to provide data on the plane distance from the ground. Installation of
other radars continued with air-road type of radar surveillance and the airport
surveillance radars, which were installed in a number of airports in the
mid-1950s. These air traffic controllers contributed with their work.
Microwave Landing System (MLS) were developed in the 1980's. These systems would
allow pilots to choose a course best suited to their model of aircraft. Having
different modes of landing can help reduce the noise around the airports and
keep smaller aircraft away from larger aircraft. In the U.S. the FAA has stopped
the engineering of MLS in 1994. The FAA has considered the use of technology
that is based on global positioning systems (GPS) instead of the microwave
system. GPS uses satellite for navigation between the airports; it is extremely
Lighting still plays an important role in the landing. Approach modern lights
can be directed to take into account all barriers near the airports that the
pilots might need to avoid before starting its approach to the runway. Lighting
can be fixed at different angles for larger aircraft, as these *****pits are much
farther from ground level and the angles of descent are different to the pilots
of those planes. Those pilots flying in the fields with no other staff can turn
landing lighting off or on themselves or can change the brightness by tuning the
radio to a designated frequency and by clicking on its transmitter.
