In the U.S., the rule is as follows. It is either similar or identical to the ICAO rules because other airports have lighting looking similar. Edge lighting that is at ground level is blue, both for taxiways and aprons. However, unusual truncation of those areas, as often occurs for construction, is in red and is often brighter because they normally use the same light bulbs and a different filter (and lightbulbs have more red than blue). Similarly, permanent obstructions such as walls, that are risks to be hit with wings rather than the edge of the area for use by the wheels, will have red obstruction lights on them. Blue edge lights are then omitted. Finally, permanenent lighting is often recessed into the tarmac. For lights stuck on obstructions/construction, this is not done. When a long way away, and standing at ground level, the recessed lights can be invisible so you can only see the ramp edge indication if it coincides with something that needs a red non-recessed light. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
