The European aircraft manufacturer Airbus has equipped the cabin of a new aircraft with several sensors that measure what passengers do on board the aircraft, according to CNBC.
The device, the A350-900, was tested for the first time last August. The purpose of the sensors is to map the needs of passengers and to save money.
Among other things, the toilets in the device are equipped with sensors, so that it is possible to measure how often the toilet is used. As a result, cabin crew know when, for example, toilet paper and soap need to be replenished.
Airbus also wants to place cameras on board to monitor how many people are waiting in line for the toilet. Then it wants to indicate live how long the queue is and which toilet passengers can use best. Passengers' faces will be blurred to ensure privacy on board.
Information is also kept about how many and what passengers order food, in order to make purchasing more efficient and to prevent waste.
The data is shared with the cabin crew via the on-board WiFi. When the aircraft has landed, the data is shared with the airline. The device will be tested until the end of this year. The sensors have not yet been tested on board commercial flights.
