Which of the following is an incorrect way to select waypoints on the GPS?

Selecting waypoints on a GPS system typically involves methods that provide exact locations or identifiers for navigation. Using speed as a variable does not directly apply to the selection of waypoints. Waypoints serve as geographical references that allow pilots to navigate from one point to another, and their selection hinges on concrete identifiers or position data rather than speed, which pertains to the rate of travel between those waypoints.

Utilizing coordinates is a standard method whereby specific latitude and longitude points are inputted to establish the waypoint's exact location. Scanning the waypoint list allows users to view and select from previously saved or available waypoints, making it a practical approach. Similarly, entering or selecting waypoints by name is common, as each waypoint is typically assigned a unique identifier that can be easily recalled.

Thus, the correct answer identifies a method that does not align with the operational functions of a GPS system in waypoint selection.
