What is an advantage of the one-step deicing process?

The one-step deicing process is advantageous because it is quicker compared to multiple-step deicing methods. This speed is crucial in aviation operations, as it minimizes the time an aircraft spends on the ground, especially during winter weather conditions where rapid deicing is necessary to maintain flight schedules. A quicker process helps ensure that aircraft can be rapidly prepared for departure, reducing delays and improving overall efficiency in airport operations.

While the other options have their merits, speed is a fundamental aspect of deicing, as it directly impacts operational effectiveness and helps maintain on-time departures.
