At least NATO reporting names for Soviet aircraft make sense:
If it begins with an "F" (e.g. Fulcrum, Foxbat) it's a Fighter
If it begins with a "B" (e.g. Badger, Bear) it's a Bomber
If it begins with an "H" (e.g. Hind, Hokum) it's a Helicopter
If it begins with a "C" it's Commercial (can't think of an example)
