Weather Hazards

  Low Level Windshear: The invisible Enemy.   The heat radiation produced by the sun  and received by the many different surfaces on earth including, forest, cities, water and inhabited areas across the globe is the main reason of the constant changes in the atmosphere. The oval shape of the planet, wider by the equator and narrower by the poles receive surface radiation differently, thus it’s cooling down process at these many areas are also different. The product of this surface cooling (land and water) of warm, warmer and cool air elevates up to the atmosphere and further cools down, depending from where the cooling is occurring the different masses of air meet in the atmosphere producing rotational movement from different air pressures, this produces high and low pressure with late enables bigger air masses to travel across earth as fronts, these front could bring serious climate change in the form of tornados, tropical storms, thunderstorms, hail, among other weather...

Air Traffic Control Entities

  NATIONAL AIR SPACE, TRAFFIC MANAGEMENT BETWEEN AIRPORT AND CENTER AIR TRAFFIC CONTROLLERS  The airspace in the United States is  complex and structure well oil machine capable to handle thousands of airplanes in the air at the same time, but what really takes to manage all the traffic at once so well. Air traffic are divided among entities, each of them responsible to handle air traffic in different sectors, altitudes and airports inside the National Air Space (NAS). For now, we discussed the roll of Air Traffic Control Towers and Centers.  In the United States the airspace is  divided into 21 zones (sectors), within each zone are portions of airspace, about 50 miles in diameter called TRACON (Terminal Radar Approach Control) airspace, and within each TRACON are a number of airports each of which has it’s own airspace that measures around 5 mile radius (FAA, 2006). These airspace structure allows traffic to flow smoother and safe (FAA, 2020).  Each entity...

The Airport and The Environment

Water Quality Issues in the Airport Environment.     Throughout time the demand for air travel  increased drastically, sometimes pushing airports beyond capacity forcing managers to plan plan on airport expansion to meet the inevitable demand. Aviation is growing, and that is generating huge benefits for the world, it’s protected that air travel will double in the next 20 years reaching 8.2 billion in 2037 (IATA, 2018).  The evident increasing demand will  require new airport infrastructure. At airports in the US alone Air Traffic Controllers (ATC) handled an a average of 53 million takeoffs and landings by 2019 a number that is projected to increase greatly in the later years (FAA, 2020). This operation saturation of air travel will trigger a robust infrastructure, increase traffic that will raise one of the concerns at airports which is water quality issues. Many airport activities result in the discharge of pollutants to adjacent water bodies such as aircraft...

Airline Safety and Federal Aviation Administration Extension Act of 2010

Image
  Legislative Act - Airline Safety and Federal Aviation Administration Extension Act of 2010 After February 12, 2009 an airplane  accident put aviation safety on the table, procedures, experience and practices were being analyzed to determine if crew member were truly qualified to operate an airline or if it was too premature to a pilot to be seated behind the controls of a passenger jet. It took a great effort from congress members, unions and airlines in general to adhere and work cohesively for the sole purpose of increasing the safety of crew and passengers. In 2010, a legislation changed the shape  of the aviation industry in the United States and the effect of the “1500 hour rule” bill was passes requiring new pilot certification, qualification and requirements to act as a pilot of an air carrier. The legislation act passed it required the FAA to draw up new lines on pilot experience, training and rest that mainly mandated to captains and first officers to posses an...

Human Factors Challenges

Integrating Maintenance and Human Factors in Modern Aviation. The challenges experienced in aviation depends on how  well a company is structured and regardless of size, companies apply all kinds of programs to help manage human error. While human errors can be caused by a lack of experience, knowledge and understanding of the material or system, it could be a direct product of fatigue, stress and other outside distractions that affect communication, decision making affecting technical skills and impacting aviation efficiency.  Human Factors have been a topic for years and statistics continue to support that human factors directly caused and contribute with the majority of aviation accidents (AMTH, 2018). Companies continue to modify and implement programs to mitigate human error but, accidents are a never ending chain. Modern aviation have focused primarily of economic growth and efficiency this combined with globalization impacts directly labor by increasing workload and dec...

Aviation Security - The Role of TSA

Image
TSA LEVELS OF SECURITY  The Transportation Safety Adminiatration (TSA)   faces one of the most challenging jobs in the nation, their main duty is to screen all passenger and personnel with a variety of security measures and training initiatives, including threat recognition and security management. These strategies focus on individual threats and its main purpose is to mitigate, reduce and stop an imminent threat. However, security still a concern, all protocols are establish and TSA continues to fight and prevent vulnerabilities (TSA, 2019).  Threat recognition is a challenge the agency faces daily, unfortunately the is not an immediate solution for everything, a collaborative process for threat recognition performs a test which consists on undercover agents that try to find the techniques used by terrorists, they attempt to pass threat objects through passengers and  baggage screening systems, and access secure airport areas. The specifics of these tests we co...

Aircraft Systems and Flight.

Cessna Citation CJ3 Hydraulic Systems and Operation. The CJ3 business jet is a very reliable aircraft, It’s the perfect combination of range, speed and operating economics (Cessna 2004). One of the most important system of this aircraft is the hydraulic system. The Hydraulic system permits the application of force by converting a volume of fluid flow into pressure on a hydraulic piston motor, in other words hydraulic pressure is converted into force to move a component of the aircraft. The hydraulic systems of the CJ3 is defined as open center hydraulic system which means that the hydraulic fluid is constantly circulating in the system at low pressure and it increases its pressure during the operation of the landing gear, speed breaks and flaps. The break system use a separate independent hydraulic system but, the same type of hydraulic fluid is used.  One of the additional benefits of an open center hydraulic system is that this low pressure greatly reduces the quantity of hydraul...
