← ScienceWhich risk increases when calibrating accelerometers inside aircraft?
A)Gravitational field inaccuracies emerge✓
B)Inertial frame becomes non-linear
C)EM interference overwhelms device
D)Temperature gradients induce stresses
💡 Explanation
Gravitational field variation leads to errors because the Equivalence Principle dictates acceleration and gravity are indistinguishable; therefore, local variations cause miscalibration rather than simple inertial frame issues under constant acceleration. EM and thermals are less impactful.
