What is the CH-46 Sea Knight's stated range?

• A. 550 nm
• B. 450 nm
• C. 650 nm
• D. 700 nm

Answer: (A)

Range is the farthest distance a helicopter can fly on its internal fuel under standard conditions, and it’s different from endurance, which is how long you can stay aloft. For the CH-46 Sea Knight, the published ferry range used in training materials is about 550 nautical miles. This figure represents typical non-stop travel with a standard load and cruising speed; real-world factors like payload, altitude, temperature, and headwinds can reduce that distance. The other numbers don’t match the standard reference data for this aircraft—they’re either below or above what the official figures show—so 550 nautical miles is the correct range to rely on in this context.
