It does this by fitting small piezoelectric acoustic sensors to parts of the structure to detect the particular frequency of noise caused by a crack in aircraft-grade aluminium.

EasyJet already offers greater frequency on its routes and makes more use of primary airports such as London Gatwick and Paris Charles DE Gaulle.

Due to its high accuracy, low-cost, full navigation states, and high output rate, the system has wide applications, such as vehicle tracking, aviation, automatic mining, and precise farming.
