Let's really confuse the issue.
The Operator decides to do the Ops Manual changes....which seat does the PIC sit in....when the otherwise Single Pilot Aircraft is operated as a Two Pilot Aircraft but both pilots are equally rated and both approved as PIC's but one is acting as designated PIC and the other as SIC although each is qualified to fly the aircraft Single Pilot when not required to have a second pilot along?
Is there a "pilot's seat" and a "co-pilot's seat" in a Bell 212/412?
