An airspeed calculation system for determining the airspeed of an aircraft includes a static pressure device, a global positioning system device, an inertial measurement unit device, an angle of attack device, a total pressure sensor, a total air temperature sensor, at least one processor, and a memory. The at least one processor is in electronic communication with the memory, the static pressure device, the global positioning system device, the inertial measurement unit device, the angle of attack device, the total pressure sensor, and the total air temperature sensor. The memory includes programming code for execution by the at least one processor. The programming code is configured to determine the airspeed of the aircraft using data obtained from each of the static pressure device, the global positioning system device, the inertial measurement unit device, the angle of attack device, the total pressure sensor, and the total air temperature sensor.
