Making the Corsair work at sea took hard testing

What process allowed the Royal Navy to use the Corsair from its carriers?

Sustained testing, including Eric Brown's work, turned a powerful but difficult aircraft into a useful shipboard fighter.

The Corsair was a high-performance aircraft that was difficult to operate from carriers. The US Navy was initially reluctant while the US Marine Corps used it ashore, leaving an opportunity for the Royal Navy to adapt it. Its long nose and handling problems demanded special procedures. Sustained testing eventually produced a major improvement in carrier fighter performance.
