I don’t think that’s the most common case for an IFF query. AWACS oversight aircraft likely issue more IFF queries than fighter intercepts do. You still want to respond to a friendly AWACS inquiry, even though that aircraft is 100nm away and no direct/immediate threat to you.
- FuriouslyAdrift 2y ago100nm (more or less) is the positive identification radar advisory zone for a carrier group airspace... (AKA REDCROWN)
- furyofantares 2y agoLess than 100 nanometers? It always gets me when someone abbreviates nautical miles in lowercase even though context is (almost) always clear it can't be nanometers.
- sokoloff 2y agoAn AWACS aircraft within 100 nanometers of you would indeed represent a direct and immediate threat. :) TIL that nm isn’t actually accepted as an abbreviation for nautical miles. (It’s used so commonly in aviation that I assumed it was correct and it took me 3 or 4 searches to accept that this thing I knew was correct actually wasn’t. Thanks [seriously]!)
