awATM is  our in-house radar display designed to meet 10-4 safety requirments and is currently under design and module testing.

 

The awATM uses resilient/robust hardware utilising dual LAN, dual disk arrays, servers.  Interfaces are all over LAN and AWprojects can supply and configure leading industry tested LAN units and converter boxes to interface (eg. Sunhillo Longhorn,RICI; Guntermann & Drunck KVM equipment).

 

The awATM uses a simplified version of the Visualizr software which has a reduced safety net count.

Safety nets can be built in as required:

 

APM: - Approach path monitoring, designed to show track compliance to final stages of predefined approaches from the Final Approach Fix to final.

             APM track monitoring can be set up for ILS, offset ILS, GP, NDB, VOR and GNSS approaches.

 

APW: - Area Proximity warning, designed to warn of infringements of the CTA/CTR by both PSR and SSR (and combined) tracks.

 

QNH-M: - The QNH monitor.  This safety net advises controllers of aircraft using mis-set QNH.  See the [Safety Net][QNH-M] page for more information.

 

TC: - Terrain Clearance.  The Instananeous display of terrain and selected building/mast heights.  The inclusion of DEM (Digital elevation models) is possible and aircraft can display their current instantaneous height.  A local correction for AOD and geoid height is made across the awATM to correct the DEM values to above mean sea level.

 

The awATM displays plots and tracks overlaid on a local map.  The maps used in the awATM are derived from the Ordnance Survey and also use AIP data for aernautical information.  See the [Maps] pages for more information.  Other map data such as approach centrelines are derived from surveyed points in the AIP and in-house software to generate WGS-84 Mercator Projection data.  The Mercator Projection maps used in the awATM have an estimated worst case accuracy of 10 meters from the Ordnance Survey positions, and 1 meter from WGS-84 surveyed positions.

 

Tracks are displayed with configurable radar data.  Selected Flight Level, Indicated airspeed and groundspeed can be displayed.  A prediction vector can be added that shows the current heading trend.

 

Radar weather can be overlaid on the  maps and displays Asterix Category 8 data as derived from the radar data stream.
