As you know the world of aviation is changing. Better, more accurate navigation systems are making aircraft flying, takeoffs, and landings safer than ever. Part of that is because of the push toward full adoption of WAAS systems and LPV landing approaches.
What is WAAS?
WAAS, which stands for “Wide Area Augmentation System” is an incredibly accurate air navigation system developed by the FAA with the goal of improving its accuracy, integrity, reliability, and availability. It utilizes global positioning satellites and geostationary (earth-orbiting) satellites to improve the GPS navigational service to allow aircraft to rely on the Satellite-based augmentation system (SBAS/GPS) for all phases of flight including landing approaches. The accuracy of the WAAS system when determining the position of your aircraft is within 3-6 feet.
What is LPV?
LPV stands for Localizer Performance with Vertical Guidance. It is the most common and most desirable approach when coming in for a landing at a US airport. It is incredibly precise and can only be done with a WAAS enabled system.
Why you will want to switch to Universal SCN-100x.x Series WAAS LPV.
It’s because of this precision that aircraft and avionics manufactures are moving away from older navigation systems in favor of WAAs-enabled systems. Is your aircraft still relying on outdated Universal SCN600 and SCN800 series software? If so, you will want to pay particular attention to the rest of this article as it will help guide you through some changes that we recommend.
Universal Avionics is Discontinuing Support of SCN 600 and 800 Series FMS Units
Universal Avionics has announced through service bulletin number 2902, 2903, and 2904 “due to parts obsolescence” they will be discontinuing repair on UNS 1C, 1C+, 1Csp, 1Csp+, 1D, 1D+ 1K, and 1K+ FMS Management Units.
What that essentially means is that any support for the SCN600 or SCN800 series FMS units will be canceled by the end of 2020. Universal will no longer be selling new units or fixing/supporting existing systems. And while the FAA is not stepping in and mandating upgrades to a SCN1000-series WAAS enabled LPV unit, there are many reasons to make the switch.
Why switch to a Universal Avionics WAAS Enabled LPV system?
You may be saying to yourself, “if it ain’t broke, why fix it.” And that’s a fair point to make, for now. But there are plenty of reasons to consider upgrading your Universal Avionics Flight Management system now.
- Universal has said with their bulletins that they will be providing limited support on existing SCN600 and SCN800 series units after December 2020. The reason for that is because they are essentially, running out of replacement parts for these units. Parts for these antiquated systems are no longer being produced, so there is a very good chance that if your existing system malfunctions in the near future (and many do), that there will be no replacement parts available to correct your issue.
- What this also means is that airports, who pay for expensive monitoring and approach systems, will no longer be updating and maintaining their older, ILS approach capable systems. Airports, just like aircraft are converting to systems that rely on WAAS LPV stations. In fact, the FAA has published nearly 7,000 different approach charts for WAAS capable aircraft that cover 1,900 airports in the United States, most of which do not have an ILS approach capability. That means that if your aircraft does not have an upgraded Universal Avionics WAAS/LPV capable system, you may not be able to land at those airports.
How not having a WAAS Enabled LPV System can cost you extra money.
In many cases, airports will divert or detour the landings on non-WAAS enabled aircraft, giving priority to aircraft landings that have a more updated system. In this case, you may find yourself circling the airfield for anywhere from 5 minutes to almost an hour. In these instances, a considerable amount of fuel is burned off while you remain in a holding pattern waiting for your turn.
WAAS/LPV is paving the way for the future.
Another point to take into consideration is if you plan to travel over the ocean with your aircraft. In order to cross the Atlantic or Pacific Ocean you need a future air navigation system (FANS) such as a FANS/CPDLC (controller pilot data link communication). In order to upgrade to FANS, you first must have WAAS enabled aircraft.
