Introduction
In 2003 Boeing started a building concept called 7E7 prior to changing it 787 in 2005. The Boeing 787 project dreamliner is to build a 20% lighter plane due fully builds from composite material, latest in flight entertainment technology, ability to carry more passengers, larger over head bins, larger cargo space, increasing nautical miles in mid range aircraft the same class as Boeing 767 and a lowest cabin pressure of any planes in the air that provide the most comfort to passengers. We will be looking at two fault trees analysis for the Boeing 787 flight instrumentation failures. In the event that there is instrumentation failures inside Boeing 787 cockpit it can cost by loss of airspeed information which is fault tree one or by loss of advisory panel information which is fault tree two.

Fault Tree One

Fault Tree One Analysis
The flight deck system for the Boeing 787 can fail but loss of cockpit instrumentation information which can be cause by loss of airspeed information. As can be seen in the fault tree in order for airspeed information to be loss the following three must occurs: Loss of Airspeed Indicator and RPM fails and Loss of Communication Information. If only 2 of the three or 1 of the three occurs then loss of airspeed information cannot occurs. In order for loss of airspeed indication system occurs only one of the following must occurs: Airspeed indicators fails or the loss of pilot aircraft speed system. RPM will fail by itself no event not to happen for it to fails. Last but not least in order for loss of communication information to happen only of the following need occurs: loss of voice communication or loss of tracking signal. And this is the entire fault trees if the loss of cockpit instrumentation
