The company SIRIUM AEROTECH SL has developed an IFE (In-Flight Entertainment) system that has the advantage of not needing STC for its installation. A minor modification to the system power is sufficient, offering that way a very competitive price-quality solution. There are 2 models: the SkyCube (up to 100 users) and the SilverCube (up to 20 users). Airlines such as Air Nostrum, Wamos and PRIVILEGE STYLE have already chosen this product to offer this service to their passengers.
