ReplyDeleteis the statement " By regulation, the funnel flaps should have provisions to be opened from a remote location" factually correct? I was under the impression that the regulation stated that the funnel flaps should be able to be closed from a remote local. As the purpose is to beable to close the flaps in the event of a fire in the engine room.
