Hydraulic System Failure and Aircraft Performance

Image
The Hydraulic system on an aircraft is very important, as it allows the operation of various aircraft components.  A failure of the hydraulic system in the aircraft can have catastrophic consequences and it is one of the most feared events of a pilot when operating a plane. But, there are multiple separate hydraulic systems, usually three, typically installed on an aircraft. The hydraulic system is used on both small and large aircraft.  For small airplanes, it is used to operate wheel brakes, retractable landing gear, and constant speed propellers.  On other larger planes, it is used for flight control surfaces, spoilers, wing flaps, and other systems (PHAK, 2016). A basic hydraulic system consists of a reservoir, pump (either hand, electric, or engine-driven), a filter to keep the fluid clean, a selector valve to control the direction of flow, a relief valve to relieve excess pressure, and an actuator (PHAK, 2016).  "T he hydraulic fluid is pumped through the syste...

How Does Humidity Impact Aircraft Performance?

Image
The primary factors most affected by performance are the takeoff and landing distance, rate of climb, ceiling, payload, range, speed, maneuverability, stability, and fuel economy. (PHAK 11, n.d.) Although humidity alone does not majorly contribute to aircraft performance, according to PHAK chapter 11, it is a factor that contributes to density altitude.  Pilots should expect a slight decrease in performance and reduced climb rate when flying in high humidity conditions (FAA, n.d.). Humidity refers to the "amount of water vapor contained in the atmosphere and is expressed as a percentage of the maximum amount of water vapor the air can hold" (PHAK 11, n.d.). However, the air is never 100% dry.  But as the water content of the air rises to higher percentages, the air becomes less dense as a result.  This increases density altitude and decreases the expected performance of an aircraft (PHAK 11, n.d.). The main factors most affected by performance in the situation of high hum...

What Does Ethics in the Aviation Profession Mean to You?

Ethics in the Workplace While I do not have a career in Aviation yet because I am only 19, I do understand the importance of workplace ethics.    After all, ethical behavior leads to safe operations, which is the number one priority of the aviation industry.  However, it is required for any successful career.    Ethics in the workplace is a lot of things; it is being honest, on time, having a good attitude, being responsible/accountable for your actions, showing initiative, and respecting your colleagues.    It is the way employees must manage their behavior and decisions from day to day.  In the aviation industry, in particular, good ethics are required from everyone to ensure safe flight.  Pilots and mechanics, for example, must be very diligent and strictly follow a code of ethics.    Any shortcuts, failure to disclose important information, or other unethical behavior could lead to a disaster.  With more than 44,000 flights...
