How long should you wait after turning off the INS before you remove power from the aircraft?

• A. 5 seconds
• B. 10 seconds
• C. 15 seconds
• D. 30 seconds

Answer: (B)

The correct answer is 10 seconds because this duration allows for the proper shutdown of the Inertial Navigation System (INS). When the INS is powered down, it needs a brief period to properly complete all of its internal processes, including data preservation and stabilization of outputs. This waiting time ensures that all data is stored correctly and that the system can shut down without any potential loss or corruption of the navigational information it has gathered. When considering the duration options, the choice of 10 seconds strikes a balance between being too short, which could lead to incomplete shutdown processes, and too long, which could be unnecessarily prolonging the power-off procedure. Thus, waiting for this designated period after turning off the INS helps maintain the integrity and reliability of the navigation system for future use.
