The instrument scan in inadvertent IMC is intended to achieve what primary aim?

• A. Maintain control by reference to flight instruments
• B. Maximize climb rate
• C. Exit IMC without external assistance
• D. Minimize engine wear

Answer: (A)

When you inadvertently slip into IMC, there are no outside cues to rely on, so you must stay in control by looking only at the cockpit instruments. The instrument scan’s primary aim is to keep the helicopter under control by continually referencing those instruments to establish and maintain the correct attitude, airspeed, and flight path. By consistently checking the attitude indicator for pitch and bank, the altimeter and vertical speed for altitude changes, the airspeed indicator for safe airspeed, and the heading indicator for orientation, you prevent spatial disorientation and keep the aircraft stable until you can regain external references or receive assistance. This focus on maintaining control with flight instruments is what makes it the best answer. It isn’t about maximizing climb rate, it doesn’t guarantee exit from IMC without outside help, and it has nothing to do with reducing engine wear.
