The most annoying part of any meal service mid-flight is when a passenger wants to get past the flight attendant and squeeze down the narrow aisle. The Cart line is a solution to this very common problem.
The cart is guided by a set of rails overhead. The brake makes the cart steadier and safer when overhead, avoiding collapse caused by turbulence. The breaks are automatically activated when the attendant is not pushing the device. This design also benefits the ergonomy of the attendants. When getting things in our out of the cart they need not bend down, this avoiding long term occupational injuries.
