# How to calculate the radius of a turn as a function of speed, bank, wing-loading, and Cl?

Although the question of how to calculate the radius of a turn of an aircraft has been answered before using only the speed and the bank angle, the reality is that 2 aircraft with the same speed and bank angle will have a different radius of turn if their wing loading is different. Furthermore, two aircraft with the same speed, bank angle, and wing loading will not necessarily have the same radius of turn. The lift coefficient of the wing must be taken into account.

Since the answer posted before is not complete, can somebody provide an equation that takes into consideration the above factors (and any others that should be contemplated)?

• Why do you think wing loading affects turn radius? It doesn't, but if we can understand your thought process better, maybe we can provide a more useful answer that addresses the misconception rather than rehashing the existing Q&A's. – TypeIA Sep 3 '20 at 15:37
