What is the recommended scanning method for instrument flight?

• A. Focus only on the attitude indicator.
• B. A continuous, disciplined cross-check cycle prioritizing AI for attitude, Altimeter for altitude, and ASI for airspeed, with occasional VSI and HI checks.
• C. Monitor only the airspeed indicator.
• D. Scan altimeter first, then VSI, then AI.

Answer: (B)

In instrument flight, you maintain awareness and control by a continuous cross-check of the instruments, focusing on the three primary sources: the attitude indicator for attitude (pitch and bank), the altimeter for altitude, and the airspeed indicator for speed. This continuous cycle keeps you aware of how the aircraft is moving through the air and ensures you can hold or change your flight path safely. The vertical speed indicator and the heading indicator are still important, but they’re checked periodically to confirm rate of climb/descent and your course.

Why this approach is best: prioritizing attitude, altitude, and airspeed gives you the essential flight picture you must manage at all times. Attitude tells you how the aircraft is oriented, which is the central control you must maintain; altitude tells you where you are vertically, and airspeed tells you how fast you’re progressing toward or away from your target. Checking the VSI and HI regularly complements this by confirming vertical motion and heading, helping you detect any deviations quickly without letting other critical information go unchecked.

Other scanning methods that focus on a single instrument or follow a fixed order that omits the daily emphasis on attitude, altitude, and airspeed aren’t sufficient for timely, safe instrument conditions.
