A variable-incidence wing differs from a simple swept-wing arrangement because the entire wing can alter its angle relative to the aircraft. The higher angle of attack produces more lift on approach while preserving forward visibility. Large flaps complemented the system, helping a high-performance fighter slow down and manoeuvre safely during a carrier landing. A structure built to withstand arrested recovery also gave the Crusader the strength for demanding high-G manoeuvres away from the deck.

How the variable-incidence wing aided carrier landings
The F-8 could change the wing's angle relative to its fuselage, producing lift for a slow approach without denying the pilot a useful forward view.
