Speed control in the terminal area is used to shape the arrival and departure flow so each aircraft reaches the same sequencing point at the right time and with the required separation. By adjusting an aircraft’s airspeed, you can fine-tune its arrival timing to fit the published sequence, maintaining consistent gaps and reducing the need to hold aircraft or reorder them. Pushing everyone to the highest possible speed removes this timing control and makes precise spacing harder to maintain, which can create conflicts and later holds. Unlimited vectoring removes the predictability that spacing relies on, undermining the orderly flow. Weather restrictions aren’t something to eliminate; they exist to ensure safe operations and can impact sequencing if not accounted for. The number-one way to support spacing and sequencing and cut holds is to maintain the planned flow through careful speed adjustments that keep aircraft arriving in the correct order and at the proper intervals.
