What altitude should be maintained per the guidance when uncertain about terrain or clearance?

• A. Maintain the lowest safe altitude or higher
• B. Maintain 10,000 feet
• C. Maintain 28,000 feet
• D. Maintain current altitude regardless of terrain

Answer: (A)

When you’re unsure about terrain or clearance, your primary goal is to guarantee obstacle and terrain separation. The safest approach is to climb to the lowest altitude that provides adequate clearance and then remain at that level or higher. This keeps you above any uncertain or rising terrain and maintains a buffer against unseen obstacles along the route. Sticking to fixed, arbitrary altitudes or staying at your current altitude regardless of terrain leaves you vulnerable to unanticipated terrain features or obstructions. By aiming for the lowest safe altitude and climbing if necessary, you ensure you have the necessary clearance even when the situation isn’t fully known.
