Doeppner explained that “it will take the pilot approximately 20 seconds to build the approach.” He has to enter four variables: the destination waypoint (the rig coordinates), the inbound course (into the wind), the minimum descent height (50 feet above the landing platform) and the offset direction (left or right) and distance. “Those steps can be accomplished at any time but usually 20 to 50 miles from the rig,” Doeppner said. Once the approach is built, the pilot presses a single button and the aircraft automatically flies the approach.
That how you see it JimL?
