Sustained aggravated spins in excess of 2 turns have the potential to exceed what limits?

Sustained aggravated spins in excess of 2 turns particularly have the potential to exceed engine operating limits. During such spins, the aircraft experiences extreme aerodynamic forces that can lead to critical situations such as overheating or mechanical failure in the engine. The prolonged descent and high maneuverability demands placed on the engine during an aggravated spin can push it beyond its designed operating parameters.

Moreover, in a spin situation, if the engine is operating at high power settings or if recovery procedures are not followed appropriately, it can lead to engine damage or failure. Therefore, understanding the limitations of your aircraft's engine during spins is crucial for safe operation and effective emergency recovery practices.
