Which systems are included in the Big 6 for load shedding?

The Big 6 for load shedding refers to a set of critical systems that are managed to ensure the robust operation and reliability of an aircraft, particularly during situations where power or battery management is crucial. Choice B is the correct answer because it accurately lists systems that are indeed vital for load management and demand control.

The inclusion of MTS (Multi-Spectral Targeting System), SAR (Synthetic Aperture Radar), Pitot Heat, Fuel Heater, Nose lens/IR nose lens heater, and KU-band datalink represents systems that, when operational, significantly influence the power load on the aircraft. Effective load shedding requires understanding which systems consume substantial power and managing their operation to prioritize essential functions without compromising the overall flight safety and mission capability.

This choice captures the essence of systems that are typically monitored and controlled in a load shedding scenario. In contrast, the other options either list systems that do not fundamentally relate to load shedding or mix components that do not collectively represent the critical systems used in these situations.
