You may have already noticed this bump on the upper part of some commercial aircraft fuselages, and since the end of last January, that of the Boeing 737 MAX. What it is for? It is called a radome, a portmanteau or fusion of the words radar and dome, which in this case houses an antenna for access to inflight Wi-Fi, and offered as an option by aircraft manufacturers.
In recent years, a number of airlines have equipped some of their aircraft with this "high tech", car roof cargo box-sized, bump, allowing passengers to surf the internet or watch live TV at 33,000 feet (10,000 metres). Terms of access conditions vary according to each company.
Onboard Internet availability promises to spread quickly. According to the equipment manufacturer, Thales, 70% of the world’s fleet will be connected in 2025.
