The fuel delivery system in many modern aircraft is complicated and made up of many different components that all work together to deliver a continuous amount of fuel to the engines. Of the various elements in the delivery system, one of the most integral is the fuel nozzle. An obstruction or any other event that may damage this component could prove devastating to the fuel system as a whole and risk a flight's integrity. In this blog, we will discuss all you need to know about the critical fuel nozzle.

Early aircraft utilized a single braking system with no backup or failsafe. The system was simplistic in design and eventually deemed unsafe, causing the regulating authorities to incorporate robust overhauls. Airlines had to address the issue of potential loss of the primary hydraulic pump, which led to the implementation of electrically driven pumps that provided an alternate supply of hydraulic pressure. However, these solutions didn’t address the loss of fluid issue. Some manufacturers began incorporating a compressed air system for emergency braking, yet, there was only a limited amount of air the tanks could hold. This led to the concept of multiple, independent hydraulic systems backed up by accumulators. This system proved to be effective as it allows for several layers of failure without losing total control of the braking system; a concept that is still used today.
