attitudeOf

The attitude of a hull against a horizon.

Heading is the nose laid flat on the horizon and measured from north toward east. Pitch is the nose above it. Roll is the angle from the level starboard direction — the horizon's own, for this nose — round to the hull's, positive when the starboard side has gone down, which is the way flight.rollRight turns it. Over a pole the level direction vanishes and the roll is reported as zero, because there is no horizon to bank against.
