Which term describes an altitude depicted on an instrument approach chart whose value is not underscored or overscored?

• A. Recommended altitude
• B. Advisory altitude
• C. Mandatory altitude
• D. Final approach altitude

Answer: (A)

On instrument approach charts, how an altitude is marked tells you whether you must meet it or if it’s just a guide. If an altitude value isn’t underscored or overscored, it isn’t a mandatory crossing or minimum. It’s a recommended altitude, a planning aid you can use to manage your descent and energy on the approach. You may descend to or maintain that altitude for efficiency and comfort, but you’re not required to stay at it unless the procedure or ATC assigns a different altitude. You still must observe any actual minimums for obstacle clearance and follow any ATC instructions. The other terms describe altitudes with binding requirements or specific segment designations, whereas this one is simply a suggested altitude to help you plan the approach.
