From the NAR High Power Safety Code

**Flight Safety.** I will not launch my rocket at targets, into clouds, near airplanes, nor on trajectories that take it directly over the heads of spectators or

__beyond the boundaries of the launch site,__ and will not put any flammable or explosive payload in my rocket. I will not launch my rockets if wind speeds exceed 20 miles per hour. I will comply with Federal Aviation Administration airspace regulations when flying, and will ensure that my rocket will not exceed any applicable altitude limit in effect at that launch site.

Interpretation: All recoveries must be made within with launch field. The nominal descent rate under parachute of a high power rocket is 15 fps or 10 mph. You are allowed to launch a high power rocket to an altitude not to exceed twice the minimum field dimension or 1500 feet, whichever is greater which means the minimum field dimension allows for a maximum altitude of 3000 ft. In a 10 mph wind a rocket will drift sideway 1 ft for every ft of altitude if the recovery system employs apogee deployment, so to insure an infield recovery, the maximum allowable atitude for an apogee deployment is reduced to 1500' when the wind exceeds 5 mph and remains below 10 mph. Above 10 mph, the maximum allowable altitude must be further reduced to as low as 750' when the wind is above 15 mph to the maximum allowable launch wind speed of 20 mph. This is explained in detail in

This is the best reason to employ a two stage deployment system in a high power rocket as the initial descent after apogee is typically 60 fps and the main can be deployed at 300' to minimize drift.
