Which term means an unmanned rocket that: (1) is propelled by a motor or motors having a combined total impulse of 889,600 Newton-seconds (200,000 pound-seconds) or less; and (2) Cannot reach an altitude greater than 150 kilometers above the earth's surface?

• A. Air Transportation
• B. Amateur Rocket
• C. Air Traffic
• D. Altitude Engine

Answer: (B)

In this context, a rocket used for hobby purposes is classified by two limits: the total impulse of its motors and how high it can fly. If the combined motor impulse is 889,600 Newton-seconds (or 200,000 pound-seconds) or less, and the vehicle cannot reach an altitude above 150 kilometers, it is termed an amateur rocket. These limits separate small, hobby rockets from larger, regulated vehicles and from space-related operations. The other terms don’t fit because they describe different parts of aviation or aren’t recognized classifications for these kinds of rockets.
