LOD for the Aerofly mobile phone version with their tiny screens might be ok, but it's way too low, (I'd guess by a factor of 10) for a PC monitor.
E.g. when watching those superb replays from tower view (if you don't zoom in a lot) the complete landing gear is missing when the plane crosses the threshold and just before touchdown a few tiny dots representing the wheels appear.
Same problem in the flyby view with the detailed airplane parts popping in and out at a way too close distance.
The LOD problem even appears in the VC. when zooming out, slip ball, flap pos. indicator, small RPM needles etc. e.g. on the 737 and MB339 vanish.
Another problem is that the runway and approach lights are alway ON, even in broad daylight and at good visibility.
Generally and especially at low viz the approach and runway lights look very realistic.
