STAGGER - The relative longitudinal position of the wings on a biplane. Positive Stagger is when the upper wing's leading edge is in advance of that of the lower wing [eg: Waco YKS], and vice versa for Negative Stagger [eg: Beechcraft D17].
Stagger: The "set" of the wings of a biplane in relation to one another in side elevation. In positive stagger the upper wing is in front of the lower, and in negative stagger the reverse arrangement applies.
A staggered design has the upper wing slightly forward of the lower. This helps give stability to stacked wings, and is usual on successful designs. Backwards stagger is also occasionally seen, as in the Beechcraft Staggerwing.
The Beech 17 Staggerwing is one of the most beautiful biplanes ever built. It won a number of air races before being used by the USAAF as a personnel and utility transport during WWII.
(a) Machines Having No Stagger.-I n machines having no stagger, the struts of the center section should be perpendicular to the propeller axis. As the upper longerons are usually parallel to the propeller axis, they may be used as a base line.
Classics span the gap from the much loved Piper cub to the much-desired D-17G Staggerwing Beech, from the Ercoupe to the 35 Bonanza.
OFFSET PARALLEL RUNWAYS- Staggered runways having centerlines which are parallel.

The Triplane system with its relatively smaller wing gaps and pronounced stagger would almost certainly have a greater value than this.
The AC location for biplanes with positive stagger (top wing ahead of the bottom
wing), is found according to the drawing below.
Other manufacturers can only envy Cessna's decision to proceed with the model 208 in the early '80s, despite what seemed a staggering introductory price of $640,000.
Ground effect reduces induced drag and the airplane is able to reach a speed where it can stagger off. As altitude is gained, induced drag increases as the effect of the ground effect diminishes.
Fully-flat
Fully flat beds offer a 180-degree flat bed to sleep on.
Herringbone
A herringbone seating formation is where the lie-flat convertible seats are arranged in a staggered design, so all passengers have aisle access.
