What evidence must an applicant provide for a Master Parachute Rigger Certificate in terms of parachute packing?

To qualify for a Master Parachute Rigger Certificate, an applicant must demonstrate comprehensive packing skills and experience with parachutes. The requirement to pack 100 parachutes of each of two types that are in common use ensures that the rigger is not only proficient but also familiar with different parachute designs and functionalities. This level of proficiency is critical for safety and effectiveness in parachute operations, as different types may involve varying techniques and considerations.

Packing parachutes accurately and consistently is essential for operational reliability, and requiring experience with two distinct types emphasizes the importance of versatility and a broader understanding of parachuting systems. This standard reflects the level of expertise expected from a Master Parachute Rigger, making option B the correct choice.
