PZL-104 Wilga - Flight Phases Classification Dataset

The dataset comprises time-series measurements acquired from an inertial measurement unit installed aboard a PZL-104 Wilga aircraft. The recorded signals include linear accelerations along three orthogonal axes, denoted as ax, ay and az, expressed in accordance with the conventional aviation reference frame. Additionally, the dataset provides orientation information in the form of Euler angles—pitch, roll, and yaw—estimated using the Madgwick algorithm sensor fusion algorithm. Each observation is annotated with a categorical variable (class) representing the phase of flight, defined as follows: 0 — engine start; 1 — takeoff; 2 — cruise and maneuvering flight; 3 — approach; 4 — landing. The data were collected during operational flights involving takeoff and landing procedures conducted on an airfield with an unpaved (grass) runway surface.
