The limitations of simulated circular approaches are recognised by the industry.
One of (the many) recommendations the RAeS International Working Group (Flight Simulation Training Device (FSTD) Qualification Standards) will make to ICAO will be to change the FOV from 40 X 180 to 40 X 200 degrees for what are currently referred to as Level C/D devices.
The much improved picture quality in terms of brightness and resolution now available from LCoS projectors coupled with vastly improved database content (due to satellite imagery) should make for much more realistic visual circuits.
