What is a characteristic of an erect spin?

An erect spin is characterized by maintaining a vertical, upright position of the aircraft while spinning, and the specific parameters for such spins are grounded in performance expectations regarding duration and altitude loss.

The option indicating a 2-3 second duration per turn with a 400-500 foot loss per turn aligns with the known characteristics of an erect spin. This period is relatively brief, as spins are usually described in terms of their turn rates, and in the case of an erect spin, the altitude loss per turn is moderate compared to other spin conditions. This suggests that while the spin is maintained, the aircraft does not lose excessive altitude rapidly, making it easier for pilots to manage.

The accurately described performance metrics are crucial for pilots to understand how they can recover from the spin and regain control of the aircraft. The other options do not fit the typical profile of an erect spin, either through longer duration or greater altitude loss, which would indicate a more extreme condition not consistent with the behavior of an erect spin.
