1. A system for training an operator, the system comprising:

  • a computing device including a processing unit and computer-readable medium, the computer-readable medium storing a training simulator application;

    wherein the training simulator application, when executed by the processing unit, is configured toreceive an operating command from the operator,generate and output a simulated training environment, the simulated training environment including a simulated ground plane and a simulated wheel loader having a simulated bucket, the simulated wheel loader and the simulated bucket positioned and moveable within the simulated training environment in response to the operating command received from the operator,determine a current position of a level-grade plane within the simulated ground plane,determine a current position of at least a portion of the simulated wheel loader within the simulated training environment,determine if at least a portion of the simulated bucket is below the level-grade plane based on the current position of at least a portion of the simulated wheel loader and the current position of the level-grade plane,when at least a portion of the simulated bucket is below the level-grade plane, generate and output an indicator having a first feature, wherein the indicator marks at least a portion of the level-grade plane within the ground plane, andwhen at least a portion of the simulated bucket is not below the level-grade plane, generate and output the indicator having a second feature, wherein the second feature differs from the first feature by at least one selected from the group comprising a color, a size, a shape, a pattern, and an animation.
