OK, this to me, is one of the most annoying features of the code as it's currently written:
If an option is unavailable at a field: ords, drop tanks, 100% fuel, whatever, then Gray It Out and display the available hanger options accordingly. What's currently available for a given aircraft should be evident at a glance when I go to the hanger.
If this is too much, then at least have the hanger graphics default to no ords, DT, etc. if they're not available. It's silly to select a loadout option, be prompted that it's not available, then have to manually set that option to nothing before you can take off. Frankly, you shouldn't even be able to leave the hanger with an unavailable loadout selected.
