 This may be displayed in the cockpit or cabin to allow the aircrew to monitor the aircraft in flight, and is usually recorded to allow the data to be analysed later.FTI typically monitors between 10 and 120000 parameters - for example temperatures inside the cargo and pressure distribution along the wing.FTI sources could be temperature sensors, pressure probes, voltages, current transducers, potentiometers, strain gauges, aircraft data buses or cameras.
