Is it true or false that when using longitudinal separation, the lead aircraft must always be same speed or faster?

Answer: A — True

When using longitudinal separation, it is essential for the lead aircraft to maintain a speed that is equal to or greater than the following aircraft to ensure safe distance management between the two. This is crucial because if the lead aircraft were to slow down significantly, it could potentially allow the following aircraft to close in too quickly, resulting in a loss of the intended separation. Maintaining this speed relationship is vital for the safety and efficiency of aircraft operations, as it helps prevent conflicts and allows air traffic controllers to manage airspace effectively. The assertion that the lead aircraft must always be at the same speed or faster aligns with established safety principles in air traffic management, reinforcing the importance of speed in maintaining proper separation in flight operations.
