Esterline CMC Electronics' WAAS GPS Landing Systems Certified
For The Aircraft
The Esterline CMC Electronics (CMC) IntegriFlight global
positioning system (GPS) landing system has been certified for GPS
Localizer Performance with Vertical (LPV) Guidance approach
operations on a Boeing 737-300 aircraft operated by Canadian North
Airlines. As a stand-alone ILS look-alike system that
smoothly integrates with existing navigation instrumentation, the
installation of dual CMA-5024 wide area augmentation System (WAAS)
GPS receivers in conjunction with dual CMA-5025 control panels
provides a highly economic approach to retrofitting aircraft with
LPV capability.
According to Chris Drossos, 737-300 project pilot for Canadian
North, "The addition of LPV capability to our aircraft permits us
to provide significantly improved schedule reliability for our
scheduled and charter clients, given the absence of traditional
ground-based approach aids at many of the remote Canadian
destinations we serve. From the pilot's perspective, CMC's
LPV system provides a clean, straightforward interface which
behaves exactly like an ILS, but with the exceptional WAAS
performance and availability."
The Canadian North installation was made possible through the
efforts of a number of organizations in partnership with CMC.
Logic-Air Aviation Services of Mirabel, Quebec, was responsible for
the development and installation of the system and is the holder of
the Supplemental Type Certificate (STC) issued by ACS-NAI, a
Transport Canada approved Design Approval Organization (DAO). Based
in Winnipeg, Manitoba, ACS-NAI also provided vital engineering and
certification support, including STC data and documentation.
In addition, the CMA-5025 control panel has been designed and
produced by Air Data Inc. of Montreal, Quebec, in partnership with
CMC. This key component allows the flight crew to select a space
based augmentation system (SBAS) final approach, based on a
worldwide WAAS approach database hosted by the CMA-5024.
CMC's CMA-5024 WAAS/GPS receiver has been certified by the FAA
and Transport Canada to TSO-C145c Beta-3 and TSO-146c
Delta-4. The latter category covers the provision of
precision approach guidance signals to the aircraft's autopilot and
instrument displays for the execution of an LPV approach.
Specifically designed for ease of retrofit and adaptability to
either existing or new-build aircraft, the CMA-5024 is an ideal
choice for any aircraft, from helicopters and business jets to
airliners. Any aircraft equipped with the CMA-5024 is also
inherently ready to support ADS-B operational regulations in both
remote and high-density traffic areas.
