The unit used to express the HH-65C's maximum speed is which abbreviation?

• A. mph
• B. m/s
• C. km/h
• D. kts

Answer: (D)

Knots are the standard unit for speed in nautical and aviation contexts because navigational distances are measured in nautical miles. The HH-65C’s performance figures, including its maximum speed, are published in knots, so the appropriate abbreviation is kts. For reference, 1 knot equals 1 nautical mile per hour (about 1.15 mph or 0.514 m/s).
