Why is compass calibration important?

• A. To improve GPS signal reception
• B. To enhance photo quality
• C. To extend battery life
• D. To ensure accurate orientation and prevent loss of control

Answer: (D)

Compass calibration is about making sure the drone’s heading readings are accurate. The drone uses a magnetic compass to determine direction, and nearby metal, magnets, or electrical equipment can distort those readings. Calibrating the compass aligns the readings with the true magnetic field in your current environment, reducing heading errors so you can maintain proper orientation and avoid unexpected yaw or drift that could lead to loss of control. The other options don’t address orientation data: GPS affects position, not heading; photo quality isn’t influenced by compass calibration; battery life isn’t impacted by calibrating the compass.
