SkyWest Aircraft Ground Group II Practice Test

Minimum service time is the shortest window allocated to complete all required ground handling tasks between flights for a specific aircraft. For United’s CRJ 700, that window is 29 minutes. This takes into account deplaning and boarding, cabin cleaning, galley restocking, baggage handling, and safety checks to have the aircraft ready for the next departure.

Why this matters: MST sets the minimum turnaround pace so operations stay efficient while ensuring all essential tasks can be done safely. A shorter time, like 15 minutes, wouldn’t reliably accommodate all tasks, while longer times, such as 45 or 60 minutes, would unnecessarily slow turnarounds and reduce aircraft utilization.
