What is the aircraft configuration required for an intentional spin entry?

Establishing and trimming the aircraft in slow cruise is the correct configuration for an intentional spin entry because it allows the pilot to ensure the aircraft is in a stable condition before initiating the spin. In this configuration, the aircraft is flying at a speed that is low enough to permit control effectiveness but high enough to maintain adequate energy for maneuvering. Trimming the aircraft aids in relieving control forces, allowing the pilot to focus solely on executing the spin entry inputs without unnecessary distractions.

Additionally, a slow cruise configuration provides better control and understanding of the aircraft's response during the spin entry, as it minimizes the potential for unintentional stall scenarios that may occur at higher speeds. It's important to note that conducting spins should only be done in a properly equipped aircraft and in a controlled environment, adhering to safety regulations and training guidelines.
