CAFUC2

OverviewThis repository hosts a high-fidelity benchmark dataset for General Aviation (GA) anomaly detection, named CAFUC2 Dataset. It comprises approximately 1 million multivariate time-series data points derived from 120 real flight sorties collected by the Civil Aviation Flight University of China (CAFUC). The dataset covers four heterogeneous GA aircraft models: Cessna 172R Cessna 172S Cirrus SR20 Cirrus SR20G6 The dataset is designed to support research in aviation safety, providing paired "Normal" (baseline) and "Abnormal" (synthetic fault) samples. Anomalies were generated via a physics-based fault injection framework that ensures thermodynamic lag and kinematic consistency. Dataset Content & StructureThe data is stored in standard .csv format with a 1 Hz sampling rate. The root directory is CAFUC2/, organized as follows: CAFUC2/ ├── normal_data/ # Cleaned baseline flight logs │ ├── C172R/ # Sub-folders by aircraft model │ ├── C172S/ │ ├── SR20/ │ └── SR20G6/ │ └── cleaned_XXXX_filled.csv # XXXX: 4-digit flight ID └── abnormal_data/ # Flight logs with synthetic faults ├── accelerrator_operation/ # Throttle Surge (Note: folder name implies acceleration) ├── course_deviation/ # Flight Path Deviation ├── engine_power_loss/ # Engine Cooling Failure └── pitch_attitude/ # Pitch Excursion Key Notes on Structure File Correspondence: Files in abnormal_data maintain a one-to-one mapping with normal_data. For example, abnormal_data/accelerrator_operation/clean_data_C172R/1.csv corresponds to normal_data/C172R/cleaned_0001_filled.csv. Key VariablesEach CSV file contains multivariate time-series data, including: Kinematic: Latitude, Longitude, Altitude, Vertical Speed, Pitch, Roll, Normal Acceleration. Navigation: Heading (HDG), Track (TRK). Engine: RPM, Fuel Flow, Oil Temperature, Cylinder Head Temperature (CHT), Exhaust Gas Temperature (EGT). Access & License License: CC BY 4.0 International.
