ERAU Commercial Checkride Practice Test

The correct answer indicates that when flying above the glide path of a tri-color VASI (Visual Approach Slope Indicator), the color amber is displayed. The tri-color VASI uses three colors—red, green, and amber—to provide important information about the aircraft’s position relative to the glide path.

When the light appears amber, it signals that the aircraft is too high and that corrective action should be taken to descend toward the proper glide path. The green light indicates that the aircraft is on the correct glide path, while the red light signals that the aircraft is below the glide path and requires ascent correction. Purple is not used in the tri-color VASI system, making it an irrelevant option in this context. Understanding this color-coding helps pilots ensure they are maintaining the proper approach for landing.
