Universal Avionics Enables LPV Capability for Porter Airlines
- Dual UNS-1Ew WAAS/SBAS-Flight Management Systems Introduce LPV Approaches to Toronto Island
With installation of Universal Avionics’ UNS-1Ew Flight Management Systems (FMS), Canada’s Porter Airlines has gained Localizer Performance with Vertical Guidance (LPV)-capability, positioning itself for increased competitiveness and customer satisfaction with its all-Bombardier-Q400 operation.
Porter recently completed its program to replace UNS-1E FMSs with dual Universal WAAS/SBAS- and LPV-capable UNS-1Ew FMSs. In November 2012, scheduled Q400 flights began operating into Billy Bishop Toronto City Airport (CYTZ) using an RNAV (GNSS) approach procedure to LPV Line of Minima in the UNS-1Ew database.
According to Norm Matheis, Universal Avionics’ Regional Sales Manager for Canada, “Porter is one of the Q400 fleet leaders in obtaining the maximum capability from the Universal FMS from coupled VNAV utilization, along with working towards advanced and trajectory-based navigation procedures. We’re grateful for having been able to play a small part in their success as they moved into the LPV world.”
RNAV LPV LOS approach procedure development in Canada has accelerated of late, driven by individual operators’ recognizance of competitive advantage through investment in technology and Nav Canada’s ILS Replacement Program. Under this program, airports can now have an RNAV LPV procedure, providing the same or even better access with associated flight completion rate as an ILS, without the costly investment in ILS infrastructure. Improved minimums are possible from the increased accuracy of a WAAS/SBAS-capable FMS, resulting in a smaller obstacle clearance boundary.
Creating an approach to Runway 08 at the downtown Billy Bishop Toronto City Airport was a unique application that showcases the capability of a WAAS/SBAS FMS-equipped Q400. The procedure designer (Air Navigation Data) created an LPV LOS procedure that was the first to be compliant with Transport Canada’s new criteria (TP308, Change 5.3). The 250 foot height above touchdown procedure minimums are significantly improved compared to existing ILS minima.
“Since the introduction of the RNAV/GNSS Runway 08 (LPV) approach at Toronto City Airport, Porter has benefitted from the lower minima and runway aligned final approach course offered by the LPV,” said Justin Tiplady, Director of Flight Technical at Porter Airlines. “The approach further increases reliability, which helps overall customer service and operational efficiency. We have already benefited from this technology dozens of times in the last three months, so it is already paying off.”
