dihedral also affects:

- ground clearance of wingtips and suspended engine pods at touch-down
as a function of both bank and pitch angle (critical condition flat
tire(s)/fully compressed oleo). Ground clearance of wingtips and
extended trailing-edge high-lift devices becomes critical especially
for low-set high aspect ratio swept-wing configurations (most
airliners). Positive dihedral is a measure to keep corresponding
landing gear length requirements down.

- fuel flow (towards the pumps) within integral wing tanks.
