In a Marshall Stack, how much additional altitude and distance does each aircraft add?

In a Marshall Stack, the standard procedure dictates that each aircraft adds a specific amount of altitude and distance to the stack in order to maintain safe separation and effective traffic management. The correct answer of 1 nautical mile and 1000 feet indicates this established standard for spacing.

Using this spacing allows for sufficient vertical and horizontal separation between aircraft in the holding stack, ensuring that they can safely maneuver without risk of collision or encroaching on each other's flight paths. This spacing is particularly important in busy airspace or during complex flight operations where multiple aircraft may be operating concurrently.

Other choices provide different amounts of altitude and distance which do not conform to the established procedures for a Marshall Stack. Adhering to the correct spacing is crucial for the safe and efficient management of air traffic. Understanding the significance of this standard is essential for effective flight operations within naval or military contexts.
