FAA Ground School Practice Test

What might be the consequences of not adhering to the proper glide slope when landing?

1. Increased fuel efficiency

2. Potential obstacles in approach area

3. Improved visibility

4. Faster landing times

The correct answer is: Potential obstacles in approach area

Adhering to the proper glide slope during landing is crucial for the safety of the aircraft, and failure to do so can lead to a range of negative consequences. When a pilot does not follow the correct glide slope, it can cause the aircraft to be too high or too low during the approach, increasing the risk of encountering obstacles in the approach area. For instance, if the aircraft descends too steeply or is too low, it may not clear buildings, trees, or other hazards near the airport. This is particularly significant in urban areas or airports that are surrounded by natural or man-made obstacles. Proper glide slope adherence ensures that a safe vertical navigation path is maintained, allowing the aircraft to land safely and in line with established safety protocols. Other options such as fuel efficiency, visibility, and landing times are not directly affected by adherence to the glide slope. Therefore, the potential encroachment into hazardous areas due to improper glide slope adherence is a critical concern when considering safe landing operations.
