What type of flying requires a PPC?

The requirement for a PPC, or Pilot Proficiency Check, is crucial for maintaining safety and competency in specific flying operations. Multi-engine aeroplanes necessitate a PPC because they involve more complex systems and handling characteristics compared to single-engine aircraft. The PPC ensures that pilots have demonstrated the necessary skills and knowledge to operate these aircraft safely under various conditions, especially considering aspects like engine failure procedures and performance management.

This requirement is rooted in the increased complexity and potential risks associated with multi-engine flying, which can present unique challenges that pilots need to be well-prepared for. Ensuring that pilots pass a proficiency check validates their training and readiness to safely conduct operations in more demanding aircraft compared to simpler single-engine operations, which do not require such checks.
