Navtech Partners with DW International on GNSS Coverage for Flight Planning

Navtech, Inc., a Toronto-based provider of flight operations services, has entered a partnership with DW International (DWI). The UK-based aviation consultancy will provide Navtech Flight Plan (NFP) customers with GNSS RAIM/RNP Prediction Services. This service, required to meet FAA Performance Based Navigation (PBN) guidelines and state requirements, fits into Navtech’s current suite and provides GPS coverage information for routes and airports as part of the flight planning process.

Navtech serves more than 350 airlines and aviation services customers. Its product suite includes aeronautical charts, navigation data solutions, flight planning, aircraft performance software (take-off/landing, weight and balance), and crew planning solutions.  Many of Navtech’s products can be configured as part of an EFB solution, including take-off data calculation, weight and balance, and aeronautical charts.

DWI is an independent consultancy which provides technical support in the fields of air navigation, civil air communications and air traffic management. The company also develops and maintains bespoke (custom) software and manages websites that support air operations. The company has access to a wide range of experienced technical experts including airworthiness and operational approvals inspectors, aviation safety engineers and air traffic management consultants.

“The relationship with DWI will strengthen the Navtech Flight Plan product,” said Bill Macey, Product Director, Flight Planning at Navtech. “We are continuously motivated to provide our customers with superior quality offerings, especially when they are supported by a partnership with a reputable aviation firm like DWI. Their reliable 24/7 service along with their initial help desk support will afford our users peace of mind.”

The GRPS service allows operators to comply with all FAA, European, ICAO and other worldwide RAIM requirements and guidelines. Specifically, real-time tailored RAIM predictions for RNAV and RNP operations are delivered through NFP via the internet to NFP users.

The service is fully automated for dispatchers/flight planners to obtain their predictions as they plan their route and the service allows dispatchers/flight planners and crew to plan around periods of reduced GNSS availability by taking all route details from the flight plan and calculating RAIM availability for all route types (such as enroute, terminal, approach) on a leg-by-leg basis. Destination and alternate airports for RNAV and RNP around the world are included. GRPS also processes GPS NANUs, evaluating and interpreting them in view of establishing their relevance to the RAIM availability.

“DWI is pleased to be working with Navtech to provide their customers with the RAIM predictions they need for GNSS-based operations,” said John Wilde, CEO of DWI. “The consistency and availability of our service provides the reliability NFP users require.”
