Ship Builders Manual: Solo Craft vs. Operations (Piloting)?


Maybe someone can enlighten me. I was wondering which feature(s) make(s) the built ship demand that it is piloted by the Pilot skill vs the Operations (piloting) skill. I've found nothing in this respect. Am I missing something?

ECM Suit and Sensors explain why on most ships there are several Sensor Operators, but when you look at engines/handling there is nothing concerning piloting.

The Core Rule book only says that Solo Crafts are most often of Small or lesser size, but does not say, a e.g. Gargantuan/Colossal Solo Craft is impossible (= the civilian trader is medium).

Could someone help me, please.
