I love those CV-580. I still have old FP. I changed but I see there are more FP in the past than today less FP. Maybe they were cut down services. I guess but I keep old FP but I replaced your new FP with ID Tail only. I see two airports CV-580 fly to shorter runway at least 2,900 Ft!! I don't know CV-580 can handle to stop landing roll or take off able lift off before end runway. LOL

BTW, I was on the very first flight of my life in 1973 North Central CV-580 from DAY to MKE. Never forget!!!
