You plan to break the altitude record for H motors with a flight to 10,900 feet. You have a field that is 6000 feet by 6000 feet. You have an FAA waiver up to 12,000 feet. Assuming no public highways or occupied buildings are in the area, what is the minimum distance between the launch site boundary and the launcher for an H-powered altitude record attempt?

Assuming no public highways or occupied buildings are in the area, what is the minimum distance between the launch site boundary and the launcher for an H-powered altitude record attempt?

• A. 100 feet
• B. 1500 feet
• C. 3000 feet
• D. The launcher may be located anywhere on the launch site to compensate for wind.

Answer: (A)

The key idea is keeping the rocket’s flight within a safe, controlled area and away from the boundary of the launch site. When planning a high-power altitude attempt, safety rules specify a minimum setback between the launcher and the edge of the launch area so that, even in a worst-case misfire or unusual wind, debris and the rocket’s trajectory remain contained inside the field. In this scenario, with a 6,000 by 6,000 foot field, an FAA waiver allowing flight up to 12,000 feet, and no nearby public highways or occupied buildings, the required minimum boundary distance is a fixed, relatively small margin: 100 feet. This is enough to keep the potential debris footprint and any excursions of the launch inbounds while still allowing a practical use of the field for the altitude attempt. Choosing a larger distance, like 1,500 or 3,000 feet, would be more conservative than necessary for this setup and isn’t required by the safety rules here. The idea that you can relocate the launcher anywhere on the site to compensate for wind is not how the minimum setback is determined; setbacks are fixed safety margins designed to protect people and property regardless of wind conditions.
