AEDD fuel quantity indications are derived from how many sensors in the fuel tanks?

The fuel quantity indications for the AEDD (Airspeed, Engine Data, and Display) system are derived from seven sensors located in the fuel tanks. This configuration allows for an accurate and reliable measurement of the fuel volume.

The use of multiple sensors enhances the precision of the fuel quantity readings by allowing the system to average the data, mitigate errors, and account for any discrepancies that may arise from variations in tank shape or fuel movement during flight. Additionally, having this number of sensors helps with redundancy, ensuring that if one or more sensors were to fail, the system could still function correctly and provide safe operational data to the pilot.

This is essential for flight safety, so pilots have accurate and continuous information regarding available fuel, which is critical for calculating range and ensuring that the aircraft operates within safe limits.
