Thunder Struck

 For this weeks post I will be talking about the effects that lightning strikes have in the aviation world. Since aircrafts fly so high in our atmosphere they are prone to all kinds of atmospheric anomalies, including lightning. " In aviation, lightning strikes are actually very common. In the US, it’s estimated that each commercial plane is hit by lightning at least once every year.  Lightning is most common near the equator, whereas the least lightning activity occurs over the oceans and polar areas ( Boeing )." (Rekosuo 2020) Most strikes happen during the planes ascend and descent phases. the plane needs to be between 5k and 15k ft for this strike to happen. Also, in order for lightning strikes to occur, the temperature has to be near zero and rain needs to be present.  I picked this specific phenomenon becuase of how often it happens. " In the United States, the Federal Aviation Administration (FAA) has a system in place to track lightning strikes on commer...

ATC vs TRACON

Image
 " The air traffic control in the United States is run by the FAA. It has five divisions for its air traffic control system, namely “Air Traffic Control System Command Center”, “Air Route Traffic Control Centers”, “Air Traffic Control Tower”, “Terminal Radar Approach Control” and “Flight Service Station”." ( Freudenrich 2021) There are five different entities when dealing with Air Traffic Control that all work hand in hand with each other. They all have many similarities while also being very different. For this blog post I decided to compare the Air Traffic Control Tower (ATCT) and Terminal Radar Approach Control (TRACON).  Both the ATCT and the TRACON play major roles in the ATC world. The ATCT is located at every airport, air station, air base and anywhere else in the world that allows landing and takeoff or any aircraft. "Towers handle all takeoff, landing, and ground traffic." (  Freudenrich  2021) The tower is basically the control center for all traffic i...

Why Not, Minot

Image
 Minot, ND USA is one of the coldest places in the continental united states. Cold and aviation do not always mix. It snows sideways and rains basically ice and this has a huge impact on the airport in town. The weather in Minot, currently is -2 with a real feel of -14 after the windchill. The grounds are painted white with snow and ice and that's including the taxiways and runway of the airport. " Minot International Airport (MOT) boasts the largest commercial terminal in the state of North Dakota, with air service provided by Delta, United, and Allegiant." (Fun Facts)  When it comes to the snow and ice in Minot, there is usually both present nine out of the twelve months out of the year. Even in these conditions the airport does not slow down. If anything traffic picks up becuase of people trying to visit warmer places.  This takes a toll on the airport because the workers still have to work outside and have to de-ice planes while ice is practically falling down. Even t...

Aviation Legislation

Image
 The legislation that I decided to right about this week is the Clean Air Act of 1970. " Clean Air Act (CAA), U.S. federal law, passed in 1970 and later amended, to prevent air pollution and thereby protect the ozone layer and promote public health." (Holst) The Clean Air Act (CAA) helped to shape the Environmental Protection Agency (EPA) and give them the power needed to fight environmental pollution. The CAA later authorized the National Ambient Air Quality Standards (NAAQS). These standards address some of the major pollutants in our atmosphere that threaten public health:  sulfur dioxide, nitrogen dioxide, particulate matter, carbon monoxide, ozone, and lead. Green House Gases (GHG) are also another pollutant that is controlled by the EPA under authorization of the CAA. When it comes to the CAA, EPA and aviation, GHG come into play. The EPA, through the CAA, created The Control of Air Pollution from Airplanes and Airplane Engines: GHG Emission Standards and ...

Threats in Aviation

Image
 For this post I decided to use the threat of smuggling drugs from foreign countries. TSA is the first line of defense for drug because of the second and seventh layer of security. The second layer is customs and boarder protection. The CBP is a layer of protecting in the Aviation world that stops drugs from being flown into the county from other places. The CBP uses animals, detection kits and other methods to uncover drugs. They also pay attention to body language and nervousness when talking to passengers.  The next layer, layer seven, is Canine. Canine is self explanatory. it is where canines are trained to be able to smell different types of narcotics that aren't allowed into the United States. Canines are taught to detect concealed humans and the odors of controlled substances, which include: Marijuana, Cocaine, Heroin, Methamphetamine, Hashish, Ecstasy. When deployed, these dog can smell most contraband that is being smuggled into the states and this is a huge factor th...

People in Aviation

Image
 Human factors, in the aviation world, is defined as a “multidisciplinary effort to generate and compile information about human capabilities and limitations and apply that information to equipment, systems, facilities, procedures, jobs, environments, training, staffing, and personnel management for safe, comfortable, and effective human performance” (FAA Order 9550.8A). When it comes to working in aviation, especially as a team, human factor ahs to come into play. A single person in a team could cause an entire operation to go south if they decided to get lazy, or cut corners, or skips steps all together. The point of taking human factor into play is to help alleviate the damage that can be caused by humans being human. Humans naturally take short cuts and skip steps, especially once comfortable with what they are doing.  The team based activity I am writing about is the preflight inspections that crew chiefs do before every flight. That preflight inspection involves two crew...

To Brake or Not Too Brake

Image
Discussion 3.2 The failure I decided to use for this post is brake failure. " Aircraft brakes stop a moving aircraft by converting its kinetic energy to heat energy by means of friction between rotating and stationary discs located in brake assemblies in the wheels. " (Olson 2019) There are so many different ways the brake system can fail and cause minor and major problems for the aircraft and the aircrew. When it comes to the entire brake system, there are many different components. There are stators, rotors, brake disc/pads, brake fluid, etc.  The stators and rotors basically work against each other to help the tires slow to a stop. The stators stay mounted to the axel assembly, while the rotors stay fixed to the rotating tire. As the tires speed up, the rotors pick up speed. When the brakes are applied the stators push their discs into the rotors disc, creating friction, causing the tire to slow.  If any of the many components involved in the brake system go bad, it can ca...
