What type of spins are prohibited during operations?

The prohibition of inverted spins during operations is primarily due to the aerodynamic instability and control difficulties they present. Inverted spins can lead to an increased risk of loss of control since these spins can generate a different set of aerodynamic forces compared to standard configurations. The recovery from an inverted spin is not well defined, and pilots may struggle to regain control, which could pose a threat to safety.

Understanding the characteristics of spins, it's also important to acknowledge that flat spins and hover spins present their own risks but are not traditionally classified in the same way as inverted spins. Standard spins are generally manageable within specific operational limits and recovery procedures. The focus on avoiding inverted spins is rooted in maintaining safe operational parameters while preserving pilot capability during flight maneuvers.
