Type 1 Helicopters are described as:

Type 1 Helicopters are described as:

• A. 6,000lbs to 12,500lbs, 9-14 passengers, 2,500 lbs at sea level
• B. 20,000 lbs, 20 seats, 8,000 lbs sea level
• C. Less than 6,000lbs, 4-8 seats, 12,000lb sea level
• D. 12,500lbs, 15 or more seats, sea level 5,000lbs

Answer: (D)

Type 1 helicopters are the largest category used for heavy lift in rope operations. They’re defined by a high gross weight, a seating capacity of 15 or more, and a substantial external-load capability at sea level. The option that matches this profile lists a gross weight of 12,500 pounds, 15 or more seats, and a sea-level payload of 5,000 pounds, which aligns with the expected characteristics of Type 1 aircraft. The other descriptions either show too few seats, or a gross weight or payload that doesn’t fit the Type 1 range (for example, one option lists 20,000 pounds with 20 seats, another is under 6,000 pounds gross, and another has 9–14 seats). This makes the chosen description the best match for Type 1 helicopters.
