Currently you can scrap an aircraft from storage, but if you take an aircraft out of storage you have to perform outstanding C and D checks.
I understand the reason for this but if you are intending to cargo convert the airframe it makes no sense and is very expensive as the conversion cost also includes both checks.
Could we have the option to 'convert aircraft' direct from storage. It makes sense and doesn't hand anyone an unfair advantage as you still are not shirking the C and D check cost, you just are not paying them twice in quick succession.
