← ScienceWhich navigational error arises during inertial flight because of the equivalence principle?
A)Coriolis effect calculation errors
B)Accelerometer drift from gravity✓
C)Integration errors with Kalman filters
D)Gyroscope precession under acceleration
💡 Explanation
The accelerometer cannot distinguish between acceleration and gravity effects, so it experiences accelerometer drift, because of Einstein's equivalence principle, and interprets gravity as a form of acceleration. Therefore, integration of these signals introduces navigational errors, rather than correcting via Coriolis effects within earth's rotation.
