The plane's position is not necessarily horizontal in a horizontal/level flight. Much depends on speed and trimming. E.g. at slow speeds the plane is usually in a 'nose-up' position in order to keep altitude.
There is only ONE speed at which a plane can fly BOTH level AND in a horizontal position. If your speed is lower, you'll fly slightly nose-up; if your speed is higher, you'll fly slightly nose-down.
