MIAT Mongolian Airlines has deployed DW International's (DWI) GNSS RAIM/RNP prediction service web-based user interface (GRPS Web UI) to support its performance based navigation (PBN) operations, including basic-RNP 1, for Hong Kong International Airport.

The web service will offer a user-friendly interface to assists flight planners and dispatchers in executing pre-flight RAIM checks, store tail configurations, aerodromes, waypoints and entire routes to reduce workload and human error.

The interface would also allow adjusting the parameters required for operations, including aerodrome / waypoints, elevation, navigation specification, mask angle, start and end time, minimum outage duration, receiver type and raim algorithm

DWI senior consultant Charles Thornberry said the selection of GRPS Web UI supports MIAT's RAIM prediction requirements.

"As more and more RNAV and RNP procedures are implemented, the requirement for RAIM continues to increase," Thornberry said.

As part of the contract, the company also offered a short training course over Webex in a bid to train dispatchers about managing and operating the web-based user interface.

In addition, the airline will continuously receive support from the DWI dedicated support helpdesk.

MIAT Flight Operations Engineering Department lead specialist Tamir said, "Now we have very simple tool for end-users to check RAIM status with a professional customer support team of."

The performance-based navigation (PBN) enables flying planes through radar, satellite or the on-board flight management system to enhance air traffic flow into and out of the airport.

PBN will also allow shorter, more direct routes that trim down flight time and fuel consumption, while resulting in reduced carbon emissions.

Based on PBN, the area navigation with required navigation performance (RNAV RNP) instrument flight procedures will allow more précised lateral and horizontal aircraft routing as well as enable aircraft to move down from altitude with no level offs in between.
