What is the maximum launch angle, measured from vertical, for a high power rocket?

• A. 10 degrees
• B. 15 degrees
• C. 20 degrees
• D. 25 degrees

Answer: (C)

The idea here is to keep the rocket's initial flight path close to straight up to stay within safe airspace and maintain stable recovery. For high power launches, the safety rule allows a modest tilt from vertical, specifically up to 20 degrees. Staying within this limit lets you accommodate small misalignments or wind without pushing the flight into restricted airspace or making the trajectory unpredictable. If you tilt more, stability margins tighten and the risk of unsafe conditions increases. The other options are either more restrictive or less safe than the standard limit, whereas 20 degrees gives the appropriate balance for a high power flight.
