Are the navigational aids allowed to rotate to pick up a signal?
Yes. They can rotate, be static arrays, active, passive. Q: Could you give us a more detail about the blue LED? For instance, the size (5mm?), the intensity, and if it will be your standard shade of blue, so that we may purchase one that is the same for testing. A: It could be as small as a standard 5mm LED or larger (you wouldn’t know). We are not sure what “standard” shades of blue are, but it would be similar to the blue LEDs used on police cars (although not necessarily as intense). It will be the ONLY blue LED illumination, so if your filters are slightly off, you shouldn’t see anything else like it. Note that other kinds of light (white light) will contain some blue components, but nowhere near as intense as the pure blue of the blue LED.
