Which navigation systems are standard in the MH-60S?

The correct answer highlights the standard navigation systems used in the MH-60S, which are the Inertial Navigation System (INS) and the Global Positioning System (GPS).

The Inertial Navigation System utilizes a suite of sensors to calculate the helicopter's position based on its previous positions and the forces acting upon it. This system is crucial for providing accurate positioning information, particularly in conditions where GPS might be unreliable or unavailable.

The Global Positioning System complements the INS by providing real-time positioning data using satellite signals, allowing for enhanced accuracy and reliability in navigation. Together, these systems ensure that the MH-60S can navigate effectively across various environments and operational conditions.

Other options describe navigation systems that are not standard or do not provide the same level of functionality and reliability as the INS and GPS. Hence, the integration of these two systems is essential for the flight safety and operational effectiveness of the MH-60S.
