DATABASES AND IMAGERY

 

The leading edge of the Alsim is its advanced graphics system with real time rendering and the visual time response of 1/30th of a second so as the ensure that there is no feeling of delay in relation to the movements generated by the flight controls. The JAR standards require that the runway, threshold, and approach lights must be perceived at a distance consistent with reality with a definition of at least 1024x768 pixels. The Alsim data base covers all of North America and Europe permitting operators in both areas to replicate routes and airfields. While some airfields are generic there are a number that are site specific andrelatively faithful representations of the air field buildings themselves - such as Calgary & Vancouver. Geographic realism is sufficient to replicate route checks with specific route topography in conjunction with the relevant navigation charts through the use of high resolution around the airports - in both populated areas and unpopulated area - which is further enhanced by 3D displays. The database originates from 3 different sources - US Geographical Survey, National Oceanic & Atmospheric Administration and the Shuttle Radar Topography Mission generating the most complete high resolution imagery and digital topographic database of earth - continuously updated. The vertical representation with 3D enhancement is in sufficient detail for a student to learn the basics of mountain flying. Ground types are defined by Global Land Coverage which offers 100 different global ecosystems with an accuracy of 900 metres.

 
 
 

As mandated under the JAR STD requirements to which the simulator conforms, the airport visuals are able to represent runways, runway markings, and runway lights up to CAT III. These requirements define the maximum accuracy and representation fidelity required for JAR certification. The non specific visual system represents runway configurations according to the Jeppesen database allowing approaches to virtually any airport in North America and Europe. This regime provides realistic opportunities for the practice of standard operating procedures, approaches and route checks which are particularly effective in mountainous areas where the topography is faithfully represented.

 

For long range corporate jet operators, approaches can be made to specific airports throughout Europe or may be used by those national or foreign pilots aspiring to hold JAR and FAR licences in preparation for the conversion flight skills tests, over the known routes utilized for approved licences.Specific airports exist for North Atlantic staging points such as Iceland allowing for credible navigation, approach and landing systems familiarization.

 

Day or night, the simulator introduces the student, or tests the professional, in all manner of flying complexities from approaches to minima, ADF approaches, ILS and GPS functions - which can be further complicated by severe icing and turbulence situations. 

  • Night exercises including circuits, flat land navigation both VFR and IFR can be faithfully reproduced in highly realistic fashion.
  • Full night through to full day can be set with changing light conditions. 
  • Wind direction and speed, cloud layers and cloud bases can be adjusted, and fog density set from 0m to 9500m.
