In IMC, how should you manage navigation and route adherence?

• A. Ignore the programmed route and rely on memory.
• B. Deviate from the programmed route to optimize weather.
• C. Use the programmed route with PFD/ND guidance, ECAM information, and ATC coordination.
• D. Turn off ECAM and navigate using external references.

Answer: (C)

In IMC, you stay on the intended course by following the programmed route with the airplane’s own guidance systems, using the PFD and ND to display the flight plan and track, and keeping ECAM informed about system status while coordinating with ATC for any changes. This approach ensures you’re aligned with the cleared route and altitude, leverages the flight management system for accurate navigation, and provides real-time alerts if anything affects the route or performance. Weather or other factors should be addressed by ATC through approved deviations, not by independently altering the route. Turning off ECAM or navigating by memory removes critical system information and automation, increasing risk of misnavigation or loss of situational awareness.
