An independently operable flight data capture and transmission device includes an aerodynamically efficient main body having a mounting bracket for securing the device onto the wings, fuselage or strut of an aircraft during flight. A sensor suite is positioned within the main body to independently capture flight data information pertaining to the flight characteristics, statistics, metrics, performance and environment of the aircraft during flight. A control unit is positioned within the main body to selectively control an operation of the sensor suite, store the flight data information within a memory and communicate with a user device. A mobile application displays the flight data information and communicates operating instructions to the device, and a power generation unit generates power for use by the system components during flight.
