What factors are considered in holding pattern design, aside from obstacle clearance?

In holding pattern design, pilot technique and wind velocities are crucial factors. The design must account for how accurately a pilot can execute the holding pattern, which involves turning and maintaining the specified course. Different pilots may have varying skill levels and techniques, which can affect the consistency and safety of the holding pattern.

Wind velocities are equally important because they can significantly impact the aircraft's trajectory. When designing a holding pattern, it's essential to consider the wind's direction and speed as it can alter the aircraft's groundspeed and drift, necessitating compensatory adjustments in the holding pattern to maintain the desired track.

Both pilot technique and wind conditions help ensure that the holding pattern can be navigated safely and efficiently, allowing for the necessary spacing and maneuvering without risk of collision or failure to maintain the path.
