How many hours must a runway incursion be reported to MAJCOM?

The correct answer is 24 hours because runway incursions are serious incidents that need to be reported promptly to ensure safety and accountability in airfield operations. According to military procedures, reporting these occurrences within 24 hours allows for timely investigations and assessments. This timeframe ensures that necessary actions can be taken to prevent future incidents and mitigates potential risks associated with runway operations.

Choosing a shorter timeframe would compromise the thoroughness of the report and the investigation process, while a longer timeframe could lead to delays in addressing safety concerns and implementing corrective measures. Therefore, 24 hours strikes the right balance between urgency and thorough reporting requirements.
