Which airspace should be avoided by traffic departing A-632F?

• A. West MUSTAND (10,000-15,000' MSL)
• B. East MUSTAND (5,000-9,000' MSL)
• C. North MUSTAND (6,500-17,500' MSL)
• D. South MUSTAND (0-4,000' MSL)

Answer: (C)

When checking airspace for a departure, think in terms of the vertical and directional boundaries of MOAs (military operations areas) and how your climb-out will interact with them. Each MUSTAND area has a defined floor and ceiling, and you must avoid entering MOA airspace unless you have explicit clearance. For traffic departing toward the north, the northern MUSTAND begins at 6,500 feet MSL and extends up to 17,500 feet MSL. As you start your climb from A-632F, you’ll pass through the 6,500-foot layer fairly quickly if heading north, so you would enter that MOA without clearance unless you route around or obtain a clearance to penetrate it. That makes the northern MUSTAND the airspace you should avoid given a standard departure path to the north. The other MUSTAND sectors either lie at different altitude bands that are less likely to be encountered on the initial climb in the specified direction, or their vertical extents don’t align with the typical climb-out profile from this departure. Therefore, the northern MUSTAND is the one most likely to intersect your departure path and is the one to avoid unless you’ve secured clearance or have a plan to stay clear of that airspace.
