AIRTRAFFIC CONTROL ENTITIES.

 RANDOM ACCESS PLAN POSITION INDICATOR AND TERMINAL DOPPLER WEATHER RADAR


Aviation Weather Display (AWD)

This weeks topic will be about the Air Traffic control entities and to be specific the Random Access Plan Position Indicator (RAPPI) and the Weather Radar and how contribute to an Air Traffic controller's day today activity. RAPPI is "... a software tool that can display aircrafts targets reported by a surveillance source of present as side-by-side display of all surveillance sources that provide data to an en-route air traffic control centre." (FAA 2020) A Terminal doppler weather radar on the other hand is used to get vital informations and warnings about:

  • Hazardous wind sheer conditions
  • Precipitation
  • Gust front
  • Microbursts
This two entities are very important to not only the pilots but the air traffic controllers. The "RAPPI workstation provides the national airspace system operations manager immediate information about the health status of the surveillance sources supporting the facility." (FAA 2020) The "TDWR's primary purpose is to timely and accurately detect hazardous wind sheer in and near terminal approach and departure corridors as well as to report information to pilots and local air traffic controllers. TDWR also provides warnings of sustained wind shifts and hazardous weather, including turbulence, to ATC supervisory employees to improve airport operation. We anticipate that NextGen Surveillance and Weather Radar Capability, a NextGen capability, will replace TDWR. Until then, we must properly maintain the TDWR system to comply with service availability requirements."(FAA) 
This two entities I believe are mostly important to the ATC because the Aircrafts first can't take off without good weather and the ATC should alway be aware of what the weather is going to be the RAPPI is important in that we are able to locate the jets wherever they are.

ENVIRONMENT IMPACT OF AIRPORT OPERATIONS

      NOISE POLLUTION       For this week, we will be diving into environmental impacts that affect the airport operations. I will be discussing the Noise issues. No-one likes noise and to be specific a jet or a plane noise, its loud and interruptive. This is one big issue that affects the day to day operation of most airports. "Since the emergence of the aviation industry, aircraft noise has been one of the most important sources of excessive noise generated by human activities." ( McGill 2016) Noise can cause serious damages to peoples hearing ability, with that being said, the government has to be very cautious of where they decide to build airports.      Aircraft noises can be caused by either the type of engine or the aircrafts frame. When the air passes through the aircrafts frame, it causes some friction and turbulence which ends up producing the loud noise. "The noises generated varies  according to aircraft size and type, and can differ even for identical aircra

LOW VISIBILITY

The Operating Environment and Aircraft Performance Aircraft performance can be affected by a lot of things. One of the major Environmental factor is Weather and to be more specific Low visibility. Weather is a very vital factor in aviation. Poor visibility may increase the possibility of pilot errors and collision with terrain or with other aircrafts. Fog and mist are one of the main factors that affects the visibility. Fog and mist are just very low clouds that sit on the ground. Fog is defined when the visibility is lower than 5/6SM while mist is above 5/6SM. In this conditions pilots have a really hard time taking off and landing the plane, jet or helicopters. Visibility doesn’t only get lowered by the fog but also sand. This is especially very common in the Middle Eastern countries where they have a lot of Sand storms. There are, however, ways of to proceed when you have low visibility. Different bases have their own criteria which they follow. For example in a base where I was sta
