What was the initial percentage of airport planning funding designated for noise compatibility planning in 1970?

• A. 8%
• B. 10%
• C. 12%
• D. 6%

Answer: (A)

The main idea here is that early airport planning funding included a dedicated portion specifically to address noise around airports. In 1970, eight percent of planning funds were set aside for noise compatibility planning. This created resources to analyze noise exposure, work with communities on land-use and development that wouldn’t amplify noise impacts, and implement mitigation measures around airports.

Eight percent was the initial designation, underscoring the effort to systematically tackle aircraft noise rather than leaving it to chance as airports expanded. The other percentages don’t fit the historical allocation from that year, which is why this amount is the best answer.
