My idea is that it will work like the NSU (Non-Standard Upgrade Form), as in it will let your aircraft go to level 11 for free, and then continue to up to level 15. The one difference is that it is necessary for any SP aircraft to obtain this form to continue to level 15, possibly by a complete requirement for a player to own one and be willing to use it.
