Torso cockpits recieve a +1 PSR, "due to its cramped space." (TO 301). This implies that a Torso cockpit is essentially a Small Cockpit.
A Buffered VDNI pilot "ignores its associated +1 Piloting
target modifier," if they are using a Small Cockpit. (IO 82).
Is a Torso Cockpit treated as a Small Cockpit for purposes of bVDNI?
