Field Aviation Offers FMS WAAS/SBAS Upgrade
Source: fly-corporate.com
Field Aviation's most recent STC (Supplemental Type Certificate), Flight Management System (FMS) WAAS/SBAS LPV (Wide Area Augmentation System/ Satellite Based Augmentation System/ Lateral Precision Vertical Guidance), is being offered as an upgrade to existing UNS-1C, C+ and 1E installations by Bombardier, or STC'd by Field Aviation.
As this STC is applicable to hundreds of aircraft, non-recurring costs per aircraft have been reduced significantly. Additional FMS models and STC'd installations will be added on an "as required" basis.
Field Aviation's design uses the Dash 8's existing precision approach flight director/autopilot input, the Microwave Landing System (MLS). With MLS being decommissioned, this provided the opportunity to employ its existing benefits, such as gain control and independent Flight Director annunciations on the existing EFIS and advisory displays. This permits the aircraft to perform optimally during "coupled" LPV approaches at lowest published LPV minimums without limiting the existing cross wind limits of the Dash 8 aircraft.
