The Ro.43 could observe the fall of shot as well as search for enemy ships. That additional role was especially useful when reconnaissance aircraft worked with battleships. Typical six-inch and eight-inch cruiser engagement ranges created less need for airborne correction. Larger guns firing at longer ranges gave an observer aloft more scope to improve accuracy. The crew's clear view through the aircraft's observation spaces supported both locating targets and reporting where shells landed.
