There's an airline with blue aeroplanes that flies both F70 and F100. They regularly interchange the types and every now and again the flight plan doesn't get updated. The aircraft fall into different wake turbulence categories....
There's another airline with green ATR 42's and 72's. Again interchanged often and sometimes the flight plan doesn't keep up. Also different wake turbulence categories.
Not picking on or criticising the two operators... Just highlighting how it can be a problem. Even for operators with one aircraft type... There aren't many aircraft who's name is such a mouthful that it causes additional R/T congestion?!
