9.2 Blog Discussion: Weather Hazards

Image
One dangerous weather condition most people have experienced is fog.  Fog is a low cloud created when the air near the ground is cooler than the dew point.   Fog can form for many reasons.  Some different types of fog are hail fog, mixing fog, freezing fog, advection fog, and radiation fog  (Ahrens & Henson, 2019) .  Hail fog forms due to the rapidly cooling temperatures after a hail storm.  Mixing fog can come in multiple forms, such as frontal fog (when rain is evaporated, cool air near the ground) or steam fog (cold air moves over warm water)  (National Weather Service, n.d.) .  Advection fog is caused by the movement of warm air over a cold surface, which is what causes fog over San Francisco  (Ahrens & Henson, 2019) .  Radiation fog is from the cooling of the earth overnight.   Fog can be deadly due to its ability to create a condition called spatial disorientation, which can be fatal.   Such was the c...

8.2 Blog Discussion: Air Traffic Control Entities

Image
  As we were learning about the job of Air Traffic Control this week, it reminded me of a recent article from the beginning of the year where a German man was arrested for impersonating an ATC authority. If you have not seen that new story, you can read it here on the New York Post . This story helped me decide the geographical location I chose to focus on.    In Europe, before a flight is able to take off, a flight plan is filed with the Eurocontrol’s Network manager Operations Center, located in Brussels, Belgium, or Brétigny-Sur-Orge, France.   This is Europe’s intergovernmental air traffic management organization that represents 43 European countries.  The network management’s job is to make flights through and within Europe safely and smoothly as possible.   They check flight plans obey air traffic rules and regulations, verify planned path follows an approved airway.  No aircraft is able to take off unless Network Management Contro...

7.2 Blog Discussion: The Airport and the Environment

Image
Dusty Environments  An environmental characteristic that significantly affects the operations of aircraft is dusty environments.  When I first heard this, I thought it was just people being overly dramatic because they had to clean the plane more.  However, a dusty environment can have significant effects on the daily operation of aircraft  (Szczepankowsk, Szymczak, & Przysowa, n.d.) . Reduce Visibility Reduce visibility is among one of the most significant risks of flying in a dusty environment.  When the pilot cannot see, they must rely on instruments to safely navigate the plane safely to the ground.   A Dusty environment can be catastrophic to aircraft as a pilot can easily be overcome by a condition called spatial disorientation and lose control of the plane.  This hazard is especially true to helicopter pilots  (FAA, 2011) . Increased Ware Dust can increase engine wear.  When a piece of dust becomes lodged between the fan and ...

6.2 Blog Discussion: Legislative Acts

Image
Many states have laws on a minimum amount of training required for someone before driving a car by themselves.   Such is the case with Maryland, requiring individuals to hold a learner's permit and a provisional license prior to obtaining a valid driver's license  (MDOT, n.d.) .   With airplanes being more complicated machines than your typical car and creating more destruction, why would it be any different from requiring proper training and minimum time for someone to receive their pilot licenses?   Luckily, within The United States, a law specifies the minimum amount of flight someone can have prior to receiving their license. This law is 49 CFR §61.109.  While this law is too long to include the entire thing within this blog, some of the basics of it is below: Single Engine Multi-engine 1: 40 hours of flight time 1: 40 hours of flight 2: at least 20 hours of flight training from an authoriz...

5.3 - Team-Based Human Factors Challenges

Image
  In 1903, 80% of aviation accidents were caused by equipment; however, as reliability has increased, accidents are rarely caused by technology.  Now, 80% of accidents and incidents are caused by human factors.  Its estimated 50% of delays due to engine issues are caused by maintenance errors, which cost the airlines up to $9000 per hour (Rankin, 2007)    What are human Factors? •         Communication problems •         Compliancy •         Lack of Knowledge •         Distractions •         Lack of Teamwork Pressure •         Lack of Assertiveness •         Stress •         Lack of awareness •         Norms   Reducing hum...

4.3 - Aviation Security

 The Changing TSA and the Layers of security: COVID-19 The TSA has many layers of security, some visible, many more not.  Like most of America, the TSA has been forced to adapt to an ever-changing world with the ongoing pandemic. Despite being forced to reduce contact, security has not decreased with the pandemic  (TSA, 2021) .  New technologies are being implemented at more airports, including plexiglass shields blocking the agents from the passengers, contactless ID checking, bag scanners that can see items in three demotions, and software upgrades to the full-body scanners  (Lanzito, 2021) . At some airports, some agents are no longer physically check identifications.  The process has become computerized, with agents merely verifying the computer's results.  A computer photographs the passenger, and the passenger inserts ID into a scanner.  The scanner determines if the traveler id is valid and verifies the travel is scheduled to travel....

3.2 - Aircraft Systems and Flight

Image
The ignition system plays a vital role in the operations of an aircraft powered by a reciprocating engine. At the heart of the ignition system is the magneto.   The magneto has been used successfully since early machines, and the first patent for one was issued in 1914  (Wild & Kroes, 2013) .  Although modern engines on automobiles do not use a magneto due to being seen as outdated technology, they are still the preferred ignition system in aircraft due to the extreme reliability, general ruggedness, and proven technology  (Crane, 2018) . As the magneto is the ignition system’s heart, without a functioning magneto, an aircraft would fail.   Without the magneto producing a spark, fuel would not be able to ignite; without fuel igniting, no power would be created; without power, the aircraft is not going anywhere (except down if it’s in the air).  A failure of the magneto can be catastrophic for the airplane  (Crane, 2018) . Luckily straight...
