ADS-B Certification: What Your Aircraft Needs For It To Certify

By Henry Cooper


In the aircraft industry, the term ADS-B is becoming more and more popular. Pilots used the terms but very few know what it really is. And since the term might be the most important technological change especially for pilots in the coming of decades, it is only right to give the basic understanding for them. Today we will talk about ADSB certification and the things we need to know about them.

ADS-B is a shorthand for Automatic Dependent Surveillance-Broadcasting. It is a system that includes certified position source capacity defined in section 91.227. This section discusses equipment performance requirements that are designed for safer flights in the airways.

This new development allows full network-wide surveillance coverage. And this full coverage makes the management of the air traffic so much better. ATC will have an easier way to determine the aircraft that are in need of assistance like a request for an emergency landing. This development leads to the next benefit that the methodology is giving us.

Section C defines the ADS-B performance requirements defined in region A. This includes the NACp, NACv, NIC, Position Source, SIL, SDA and the Total Latency. It contains the values that the technology must be set for it to pass the certification.

The letter A means automatic. Automatic defines that the aircraft should be properly equipped so that it will be able to send its GPS position automatically. To explain further, these new development allows the pilots to focus to the air movement around them while the system continually sends its position to the ATC. This allows much safer flights.

This methodology is also environment-friendly. It reduces carbon dioxide waste that older technology is actually producing. That would be amazing news for the environmentalists out there.

Next, we will have a letter S that stands for surveillance. This means that the framework is a surveillance technology that allows the Air Traffic Control (ATC) to watch the movements of the airplanes. Well, surveillance is keeping an eye on a certain target, and in our case, it is keeping our eyes on the air movement.

The last letter which is letter B stands for broadcast. This simply means that aircraft that are ADS-B enabled system broadcast their GPS location to other aircraft and the ATC. Broadcasting is simply transmitting information that other airplanes can use to compute for safer air passage. ATC also uses the information transmitted by the airliner to determine its location whenever something goes wrong.

We now have a glimpse of all the possibilities that ADSB is capable of doing. But we will have to wait a little while before the system would be globally accepted as the modern means for a much-improved flight experience. And with the certification, safer flights would be made more accessible.
