Navigation Improvements

Wide Area Augmentation System / Satellite-Based Augmentation System Capabilities
With the WAAS/SBAS-capable FMS, you have access to all RNAV (GPS) approach types including the most precise and accurate GPS-based approaches available today. With Minimum Descent Altitudes (MDAs) as low as 200-feet with 1/2 mile visibility, this approach type improves safety and accessibility to airports which have much higher minima or no IFR approach at all.

The WAAS/SBAS-FMS meets stringent internal monitoring requirements to provide guidance to any of the MDA levels available for RNAV (GPS) approach guidance:
  • Localizer Performance with Vertical (LPV)
  • Lateral Navigation/Vertical Navigation (LNAV/VNAV)
  • LNAV-only
Advantages of WAAS/SBAS-FMS:
 
  • LPV approach capability provides you with ILS-like guidance down to near CAT I ILS minimums (as low as 200-feet with ½-mile visibility).

  • The integral GPS/WAAS receiver is certified to provide navigation accuracy within 0.01 nm with 99.999% availability when in the WAAS coverage area.

  • Enhanced integrity and accuracy monitoring removes the RAIM prediction requirement.

  • Allows you to plan GPS approaches to your flight plan destination as well as an alternate.
  • Allows approaches at smaller municipal airports at night when no local altimeter setting is available.

  • Access to all RNAV (GPS) approaches – there are currently over 1,500 RNAV (GPS) approaches approved for use with WAAS worldwide, and more are being added every day.

  • Universal’s GPS/WAAS receiver is TSO-146b, Class Gamma-3 and the WAAS antenna was the first to receive the TSO-C190 certification for a WAAS antenna.
