Although
https://www.ufopaedia.org/index.php?title=Skyranger makes it clear that Skyrangers (well - unarmed crafts in general I guess) have a rearming step after returning from a mission in the original game, it might make better sense to split up the rearming procedure
https://www.ufopaedia.org/index.php?title=Rearming into rearming and readyness check procedures.
This would mean that crafts with no weapon mounts or no weapons mounted would just go through the readyness check after refuelling/repairing before being ready for action again.
From how I interpret the description on
https://ufopaedia.org an additional hour of maintenance is currently imposed on the craft through the rearmament step in addition to the time requirements of the "hidden" readyness check.
Changing this would be a clear deviation from the original implementation, but I would argue that it still fits in with the goal of creating a remake to the degree that it makes sense. Is this a fringe case where the logic of UFO:EU is wrong, or should it remain the same as in the original? What do you guys think?
