By now, everyone on the general aviation industry is tired of hearing about NextGen and its amazingness, right? I mean, it all sounds great - until you realize that in just a few short years, that new avionics upgrade you got a few years ago could be almost worthless.
While it will be beneficial to have ADS-B, weather mapping and CPDLC, these fancy upgrades don't come cheap. And it's not just the high dollar that destroys people's optimism. There are other decisions involved, too - like whether to upgrade now, wait until the equipment is required or just start over with a brand new jet. Add to this an overabundance of confusing FAA rules, the need for STCs, waiting for paperwork to go through and aircraft downtime, and it's a pretty unappealing process for the typical Citation or Gulfstream owner.
But NextGen has its benefits, too, in the form of safety and efficiency, and maybe it's time for everyone to get on board. But what exactly will you need? When should you equip your aircraft? How much will it cost? Should you upgrade or sell?
In this two-part series, we'll look first at the requirements of NextGen, the equipment upgrades in question, what is mandated and what will be mandated soon. In part two, we'll examine insider opinions and go over some advantages and disadvantages of upgrading avionics versus replacing your aircraft.
If you're not familiar with The FAA's NextGen program and all that it entails, it's time to get cozy with it. The program is a complex one with many different facets within it, including a series of new technologies that will allegedly make the nation's airspace more safe and efficient. A few of these new systems are especially important to aircraft owners because of the high cost and complex avionics involved. We'll go over two of the more significant systems below:
ADS-B, or Automatic Dependent Surveillance-Broadcast, is the most accurate system to date for determining aircraft position. Because both ATC and other pilots in the area will be able to determine your aircraft's precise position while flying, ADS-B will allow for reduced separation minimums and a safer flight environment.
According to an FAA mandate, all aircraft owners that intend to fly in class A, B or C airspace must be equipped with ADS-B Out capabilities by January 1st, 2020. This sounds easy enough, but the exact installation requirements vary greatly from aircraft to aircraft, depending on the current avionics package and the type of flying accomplished.
At a minimum, aircraft will need to be equipped with a WAAS-enabled GPS receiver and (for aircraft flying above 18,000 feet) a 1090 MHz ES link with a Mode S Transponder.
ATN-B1 (Datacomm) and FANS-1/A:
ATN-B1 has many names. It's known by the FAA as Datacomm and it's known still to others as Link2000+, PMCPDLC, or CPDLC. It uses datalink technology to send data communications from air traffic controllers to the cockpit of the aircraft via a text message, and vice versa. The FAA's Datacomm program intends to improve communication by reducing voice communication errors that come with fuzzy or congested radio frequencies and improving the accuracy of transmissions. Currently, there is no FAA mandate for the use of Datacomm in the United States, but ATN-B1 will be mandated by EASA in February 2015. The program is expected to be implemented in the U.S. in 2016 and expanded on until 2024.
FANS-1/A is a datalink system that incorporates CPDLC with a surveillance feature called ADS-C. The ADS-C feature provides position reports over areas not served by ground systems, such as the Atlantic Ocean. FANS-1/A is mandated by the North Atlantic Track System (NATS) for the two center tracks over the Atlantic, and this mandate is expected to expand.
Whether an operator decides to equip with ATN-B1 or FANS-1/A will largely be determined by mandates, cost and the aircraft's current equipment status. But one thing is for sure: These datalink upgrades are something operators should prepare for in one way or another.
