What is 'differences training' in the context of type ratings?

• A. Training addressing differences between aircraft types/variants to ensure safe operation
• B. Training in aerobatic maneuvers
• C. Training solely on weather interpretation
• D. Training to perform aerial photography

Answer: (A)

Differences training focuses on addressing the differences between aircraft types and variants to ensure safe operation. When a pilot already holds a type rating for one variant and will operate another variant within the same type, authorities require this training to highlight how the two differ in systems, performance, handling, and procedures. It covers variant-specific items such as cockpit layout changes, different automation behavior, performance limits, and revised checklists, so the pilot can operate safely without surprises. This is distinct from unrelated areas like aerobatic maneuvers, weather interpretation, or aerial photography, which are not part of differences training.
