Nothing better than a little bit of Nahrfolk and miles and miles of ocean for the propagation of RF!
As I said in my post, I'm going to stick to talking about the systems I actually KNOW about so I'm not in a position to talk about military ILS. Promulgated ranges for the Marham ILS were surely published somewhere?It's got to be a different ball-game from a regulatory viewpoint anyway hasn't it? The CAA/ICAO lay down our standards in civilian life but I don't know what applies in the military.
If I remember correctly we only had an output power of about 25watts on the localiser array at Heathrow so plenty of room for improvement with a decent RF amplifier.
How is flight checking achieved in the military? I imagine that FRA up at Teeside are involved? Anyone from FRA care to add their h'apenny's worth?
