... for a trajectory correction can be determined using the maximum allowable dogleg severity and other limitations. For example, if the maximum added dogleg severity is 2°/100 ft, and the current orientation angle error (i.e., deviation angle in Fig. 1 ) is 6°, then it is know that at least 300 ft is required...
