In an aircraft, many systems work in synergy, but in this blog post, I will write about issues arising in the fuel system. The fuel system is designed to deliver an uninterrupted supply of clean fuel from the fuel tanks to the engine, in a continuous flow. It must be available to the engine under all situations of engine power, altitude, attitude, and throughout all allowed flying maneuvers. There are two kinds of fuel systems: the gravity-feed system, which utilizes the force of gravity to get fuel to the engines; and the fuel-pump system, in which aircraft have two fuel pumps. In this system, the main pump system is powered by an engine, with an electrically powered auxiliary pump available for use during engine startup and in the event that the engine pump fails. The fuel system is composed of different parts, including the fuel primer, fuel tanks, fuel selectors, fuel gauges, fuel strainers, sumps, and drains. Due to all of these components, there are many issues that could arise...

There are many environmental factor that affect aircraft performance, however, for this blog post I have chosen to discuss icing. In a study conducted by the ACTF in the     2011 – 2015 period, they found that in LOC-I accidents, 42% met with meteorological threats, of this percentage, 40% encountered icing conditions. Hence, this threat plays a substantial part in the total number of LOC-I disasters. When big convective clouds hold vast amounts of super-cooled water liquid droplets being below 0 degrees Celsius, these droplets are inclined to freezing instantaneously and adhering to the airframe. When not overcome by in-place anti-icing systems, these droplets can result in a decrease of lift and an increase in weight of the airframe which due to the implications of aerodynamics, may lead to a decrease in aircraft performance, resulting in a catastrophe. Icing in engine intakes can disrupt the engine gas path, as well as icing in probes and sensors can cause system failures a...

  Ethics in aviation mean many things different things to me. By definition, ethics means the set of principles the industry has been built upon, in order to communicate its root values. Ethics, therefore, are applied to everyone in the industry, from its workers (including pilots, air traffic controllers, mechanics, engineers, etc.) to its chief executive officers and policy-makers. While thinking of how to approach this post I realized ethics mean safety. When speaking of ethics not all decisions are life or death, but privacy, transparency, integrity, and fairness are among the most important factors. This is especially true in Aviation, if employees and policymakers are not held up accountable for their actions and maintain good moral standards and follow regulations (such as the ones being set by the FAA), events could be tragic. When passengers choose to transport in airplanes or jets, they must feel safe knowing employees of all departments are following the higher standard ...
