This Boeing document discusses engineering aspects of a modern commercial jet airliner environmental control system (ECS), focusing on cabin air quality. News media coverage suggests that aircraft cabin air quality is a serious concern. However, an objective review of pertinent data and comprehensive testing do not support this perception….

Simple needle, ball, and airspeed flight information has been replaced by aural, visual, and tactile warnings incorporated into modern flight decks to alert flight crews when certain airplane parameters are exceeded. However, to prevent airplane accidents or incidents, flight crews need to know how to react properly when they encounter contradictory flight deck information or…… Continue Reading →
Modern large transport aircraft have an increasing amount of automation and crews are placing greater reliance on this automation. Consequently, there is a risk that flight crew no longer have the necessary skills to react appropriately to either failures in automation, programming errors or a loss of situational awareness. Dependence on automatics could lead to…… Continue Reading →
Reventable accidents and incidents related to erroneous flight instrument information continue to occur despite improvements in system reliability, redundancy, and technology. In particular, modern flight instruments provide more information to the flight crew with greater precision. Flight crews seldom are confronted with instrument problems; however, when these problems do occur, their rarity can make the…… Continue Reading →
The MMEL and the MEL are both designed to ensure that an acceptable level of safety is respected, when an aircraft is dispatched with inoperative equipment. The MEL enables Operators to rapidly dispatch an aircraft, and avoid unnecessary delays or flight cancellations, without sacrificing safety. Both the MMEL and the MEL are legal documents that…… Continue Reading →
In-flight fuel imbalance occurs when the quantity of fuel between the fuel tanks in the left and right wings is unequal. A fuel imbalance can occur for many reasons, including acceptable variations in the performance of fuel system components, variations in engine fuel burn characteristics, faults in internal fuel system components, or fuel system or…… Continue Reading →
All airplanes equipped with instrument landing systems are vulnerable to capturing erroneous glideslope signals. Boeing, the International Civil Aviation Organization, and the U.S. Federal Aviation Administration are working together to improve awareness and prevent such errors. Flight crews can help manage the risk by understanding the problem and performing glideslope confidence checks…. Continue Reading →
