How air spotting fitted Royal Navy gunnery doctrine

How much effort did the Royal Navy put into aircraft spotting for battle-fleet gunfire between the wars?

It preserved long-range spotting, but heavy night-fighting practice and a doctrine of closing to decisive range limited how central aircraft became.

British capital ships retained an air-spotting capability for long-range gunfire. Nearly half of their practice engagements were at night, however, when aircraft observation contributed much less. Long-range fire was expected to damage or mission-kill an opponent before the fleet closed to a decisive range chosen from intelligence about the enemy. The answer distinguishes the Royal Navy's approach from American and Japanese hopes for battle at still greater distances.
