A lift machine including a frame, a platform movable relative to the frame and structured to support a user, and a range and position determination system. The range and position determination system including a base unit coupled to the frame and structured to determine a platform position relative to the frame, a human machine interface structured to identify a desired position, and one or more processing circuits structured to: receive a total weight of the platform, determine distance and orientation information of the desired position, query a load map, return an acceptable status when the distance and orientation information and the total weight are within the operational envelope, return an unacceptable status when the distance and orientation information and the total weight are outside the operational envelope, and output the acceptable status or the unacceptable status to the human machine interface for display to the user.
