Question

describe at least 3 equipments of NextGen as it relates to future air traffic management and how would it contribute to safety of the skies ( include one equipment from navigation, communication and surveillance and focus mainly on how the particular equipment is supporting the safety) 500-600 words   

Answer 1

NextGen three equipments related to air traffic management are as follows:

1) Performance base navigation( PBN)

• Performance based navigation works on GPS satellites and cutting edge aircraft navigation equipments.
• With the advantage of these PBN creates new pathways for the aircrafts.
• Aircrafts can take shorter, more efficient and safe routes to the destination.
• This system helps the passengers in making connections or catch time saving or earlier rides home when aircraft is taking short route or burning less fuel.

2) Data communications (Data Com)

• In current scenario, pilots and air traffic controllers talk on radio which is risky and conversations are misunderstood mostly which is not safe.
• NextGen equipment Data Comm deals with this situation as pilots and air traffic controllers equipped with this capability can quickly send and respond to typed electronic messages which is safe and facilitates clear conversations.
• Data Comm facilitates security of clear communication and exchange of important information.

3) Automatic Dependent Surveillance-Broadcast (ADS-B)

• Currently air traffic management system is using radar technology to observe and track air traffic which is less reliable.
• NextGen equipment ADS-B functions with satellite to observe and track air traffic.
• Satellite technology is more efficient and reliable than radar technology in observing air traffic and ADS-B facilitates this technology.
• Aircrafts equipped with ADS-B out transmitter can send information about their position, altitude, heading, ground speed, vertical speed, call sign and International Civil Aviation Organization identifier to a network of ground stations efficiently and safely.
• Pilots of aircrafts equipped with receiver of optional ADS-B can receive traffic information and several other benefits related to safety.

So, these are 3 equipments by NextGen related to air traffic management and security purposes. These are launched or going to be launched completely by 2020.

If you like the answer then kindly give good ratings this will motivate me to answer well. Thanking you.
