Pilot’s notes
The upper wing usually sits forward of the lower — positive stagger — to clean up the airflow and open the pilot’s sight line over a nose that blocks the view straight ahead. The whole cellule is trussed by wire: flying wires carry the lift loads aloft, landing wires hold the wings up on the ground, and slack in either one means the rigging is out.

Flying vs landing wires
The two wire sets do opposite jobs; a preflight on a biplane is a walk around the wires as much as the wings, feeling each for tension and fray.
