Yes, I know, but HTC doesn't publish that data so we can't ask for it. Here. I'll make it as accurate as we can get with the data available to us.
<x kills+deaths/month = hangar queen
solve for x. x may be described as a percentage.
Well ok then. I'm thinking like in RL. Hanger queens were planes that for whatever reason, rarely saw action( think usage, sorties)and was therefore confined to the hanger. ergo Hanger Queen. So from that perspective we have a few in AH. In reality, it doesn't matter if a plane had 500 kills one tour but only upped a dozen times, compared to a plane that upped 500 times but maybe only landed a small number of kills. The plane (in this example) with 500 kills and little usage, would be considered a hanger queen compared to the one that upped 500 times, because it had the greater amount of usage, not kills.
