      Engine Running Rough at Idle For the engine rough at the idle phenomenon, as a technician, we must identify and fix several systems to find the cause of the rough engine. We'll go over some of the systems that are best suited to identify the cause and provide a solution to the problem. The cause of rough idle can be related to cracked engine mounts, the mixture being too rich or lean, induction air leak, plugged injector nozzles, uneven cylinder compression, faulty ignition system, fuel pressure too low, and lead deposits on spark plugs (Crane, 2018). First thing to do to solve the problem is checking the engine mount, check if the mixture is rich or too lean, and if so, adjust the idle mixture. The engine will always run at its best and smoothest when the mixture is rich, however it will run rough in the lean mixture. Different cylinders will operate at different air-fuel ratios, so engine roughness occurs when the mixture is maldistribution (Mike Busch. 2013...

    Flight Management System Large commercial planes a few years ago often had extra crew members. Crew members include a flight engineer responsible for managing engine performance, and fuel systems. In addition, the aircraft also have an additional navigator, they are responsible for planning the route and ensuring that the pilot follows the previously planned route, and responsible for checking the position of the aircraft. However, now computers have been developed and put into operation to replace the flight engineer and navigator to reduce their workload. An FMS can be thought of as a master computer system that has control over all other systems, computerized and otherwise. As such, it coordinates the adjustment of flight, engine, and airframe parameters either automatically or by instructing the pilot how to do so. All aspects of the flight are considered, from preflight planning to pulling up to the jet-way upon landing, including in-flight amendments to planned cou...

  Swissair Flight 111 Swissair Flight 111, the investigation found that an electrical arc in the wiring above the cockpit ceiling initiated the fire. This highlights the vulnerability of aircraft wiring to degradation over time, which can lead to arching and electrical failures. The wiring insulation in aircraft is subjected to numerous environmental and operational stresses, including temperature variations, vibration, and mechanical wear. Over time, these factors can cause insulation degradation, exposing wires and increasing the risk of arcing. Additionally, poor maintenance practices or inadequate inspection procedures may fail to detect and address these issues in a timely manner. Importance of Aviation Maintenance Mechanics Aircraft accidents, such as the tragic crash of Swissair Flight 111, often result from a culmination of factors, including mechanical failures, human errors, and inadequate maintenance practices. Aviation maintenance mechanics play a pivotal role in ...

      Critical Analysis of Swissair Flight 111 Accident and Contributing Factors   Huong Trinh Swissair Flight 111, a McDonnell Douglas MD-11, tragically crashed into the Atlantic Ocean on September 2, 1998, from JFK International Airport to Geneva, Switzerland. “The accident was investigated by the Transportation Safety Board of Canada (TSB). The TSB concluded that an arcing event from an electrical wire associated with an in-flight entertainment system that had been installed via an FAA approved supplemental type certificate was likely associated with the fire initiation event” (FAA, 2024). This critical analysis aims to delve into the factors contributing to the accident, including the aircraft's electrical system, materials used in its construction, and organizational aspects. Electrical System Design and Maintenance The electrical system of an aircraft is crucial for its operation, controlling various functions such as communication, navigation, ligh...

      Integration of Audio Filters in Aviation Communication Systems   Huong Trinh In aviation communication systems, the seamless integration of various components such as amplifiers, oscillators, transmitters, receivers, microphones, and speakers are crucial for ensuring clear and reliable communication between pilots and air traffic controllers. One essential aspect of these systems is the incorporation of audio filters, which play a significant role in eliminating noise and enhancing the intelligibility of transmitted signals. This synopsis explores the function of audio filters in aviation communication systems and their integration with other components to achieve optimal performance. Aviation communication systems rely on the transmission and reception of audio signals to facilitate communication between pilots and ground control personnel. These systems comprise several interconnected components, each serving a specific function in the transmission and ...

  Thunderstorms are extremely dangerous weather phenomena for aviation operations and are a terror to planes in the take-off and landing stages. Thunderstorm, if understood simply is an electrical discharge between charged clouds and the ground, which is often accompanied by thunder or lightning. Thunderstorms are dangerous in that when the plane flies into the thunderstorm area, it is easy to be struck by lightning, then the indicators on the plane are often seriously skewed, making it difficult for the pilot, besides the freezing phenomenon, there is strong turbulence causing the aircraft to shake, affecting the health of passengers and crew. When an aircraft is about to take off, heavy rain reduces the pilot's visibility, not to mention strong winds and gusts that can cause the aircraft to deviate from the runway. With just enough heat, moisture, and dynamic factors in the air layer near the ground, thunderstorm clouds will form. In the main summer months, when the sun is larges...
