Currently, FlightGear (SimGear, actually) always sets visibility to near-nil when the plane is inside a cloud layer -- obviously, the right and proper solution is 3D clouds, but until we have that working, or at least until we can detect whether the plane is actually near the cloudy part of a texture, I suggest that we do not limit the visibility when the cloud coverage is under 50% (i.e. scattered, few, or clear).
It's a bit of a hack, but it does make it possible to fly VFR under conditions that are legal VFR -- it's quite normal for VFR pilots to climb through a scattered cloud layer, for example (our scattered texture might be a little too busy for realism, though). You should have everything go white when there are only a few clouds in the sky. I'd like to commit this (very small) change. Are there any objections? It's especially useful with --enable-real-weather-fetch, where otherwise a low layer of few clouds gives you IMC right off the end of the runway. Here's the complete summay: clear: normal vis few: normal vis scattered: normal vis broken: low vis overcast: low vis cirrus: low vis Thanks, and all the best, David -- http://www.megginson.com/ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
