The Takeoff of the UAV

            Like a majority of new technologies, the UAV’s origins began with military application in mind. Would you believe me if I told you that the concept of the UAV is dated all the way back to World War 1? In 1917 a man named Elmer Sperry received the first military contract for the development of his “aerial torpedo” which was an unmanned flight system used to attack the enemy (Blom 2010). The way this technology worked was through the use of gyroscopes to keep the aircraft level and a type of counter that was attached to count the number of propeller rotations. Once the counter hit its preset number, the engine would cut off sending the “aerial torpedo” towards the ground and hopefully at or near its target. Rudimentary yes, but all great technologies have their origin stories. Similar to most other technological developments, inventors improve and add on to the components designed by the predecessor as breakthroughs and advancements are discovered. The UAV is no stranger to these advancements as we look at the current state of the UAV today compared to its “aerial torpedo” origin days.

            Besides military operations the FAA categorizes UAS (unmanned aerial systems; what the FAA calls UAVs/Drones) into 3 different types of operation. The 3 types the FAA recognizes are: public operations (governmental), civil operations (non-governmental), and model aircraft operations (recreation/hobby use). Each operation has specific rules and regulations they must abide by including the airspace the can operate in, the purpose of the operation, etc. For the first type (public operations) the FAA issues a Certificate of Authorization that permits the operator to use a defined block of airspace with special safety provisions unique to that operation. A COA is generally issued and valid for two years (faa.gov/uas/public_operations). The reason for the issuance of the COA is to ensure a level of safety is implemented in UAS operations so there is no interference with manned flight and various other aviation operations that would be conducted in that area of operations. Since there’s no one in the aircraft, operations must be conducted with either someone observing the unmanned aircraft in a manned aircraft with eyes on it, or someone on the ground so separation from other aircraft can be verified. Currently common uses of UAVs in the public operations include law enforcement, border patrol, disaster relief, search and rescue, and hazardous meteorological observation (faa.gov/uas/public_operations).

            The 2nd type the FAA recognizes which is civil operations includes the use of UAVs for non-governmental use. In order to gain FAA authorization to fly UAVs for civil operation, the FAA requires either a Section 333 Exemption or a Special Airworthiness Certificate (faa.gov/uas/civil_operations). The Section 333 Exemption grants exemption (but still needs to abide by COA and Section 333 regulations) from requiring a COA as long as the commercial operation is in a low-risk, controlled environment. The other form of authorizing your UAV commercial usage is through a SAC (special airworthiness certificate). Obtaining a SAC requires the operator to describe how their system is designed, constructed and manufactured. The software development and control of the system, its configuration management, the quality assurance procedures used, as well as how and where they intend to fly their UAVs (faa.gov/uas/civil_operations). The SAC extends on to the experimental use of UAVs for civil use through the FAA Order 8130.34 which inspectors use when a civil UAV is being used for things like research and development, crew training, and market surveys. When civil UAVs aren’t being used for experimental purposes, the range of operations can include things like land surveying, 3-D mapping, logistic delivery, sports/news/and film recording, and even becoming their own mobile WiFi hotspots.

            The third type of operation that the FAA recognizes is called model aircraft operations and is used for recreational and hobby use only. This category has proven to be the most challenging to regulate and has proven to cause the most issues with manned aircraft in terms of airspace violations. In order to reduce these kind of incidents, the FAA and other industry associations came up with the Know Before You Fly campaign designed to educate new incoming drone/UAV users to the NAS (national air space). Some safety guidelines outlined in the Know Before You Fly website are to fly no higher than 400 feet and remain below the surrounding/highest obstacle around, keep your UAV in eyesight at all times, do not interfere with manned aircraft operations, remain 25 feet away from individuals and vulnerable property, and to contact the airport and control tower before flying within 5 miles of an airport or heliport (knowbeforeyoufly.org). In order to remain in the recreational category which means no required FAA authorization, a UAV is NOT allowed to be used for compensation or sale (faa.gov/uas/model_aircraft). The FAA began a registration process for model aircraft requiring all model aircraft that weigh 0.55lbs to 55lbs to be registered in the aircraft registry database created by the FAA. I believe they initiated this requirement to aid in regulating and punishing those drones that violate the safety guidelines or who interfere with manned aircraft operations (like colliding with planes near airports or causing distractions). The response so far seems positive though because as of January 22, 2016 (30 days after the UAV registration opened) 295,306 drones had been registered in the FAA database (Huerta 2016). In an effort to aid in FAA compliance, drone developer DJI has begun beta testing for a firmware update in their drones called GEO (Geospatial Environment Online) which gives DJI drones real time updates on no-fly zones (Lavars 2016). The firmware is being honed to disable DJI developed drones if they were to enter these no-fly zones reducing the hazard UAVs pose when in the vicinity of manned aircraft.

            The UAV continues to develop and takeoff in the recreational and civil operated market. According to a market forecast conducted by Grand View Research, from 2014-2022 the UAV market plans to grow 17% (http://www.grandviewresearch.com/industry-analysis/commercial-uav-market). This is after the fact that the global commercial UAV market size was valued at $500 million USD; so using that number, a 17% increase over an 8-year span of $500 million USD equates to about an increase of $10.5 million USD per year. The government (public operations) will remain to control the majority of the market through this forecast with a 40% contribution to global UAV revenue in 2013, but as illustrated in the graph created by Grand View Research; the Energy and Other revenue categories increase substantially as the year’s progress.  With the announcement of Amazon Prime Air and the increased development of VR (virtual reality), I think the UAV technology will continue to prosper and become heavily integrated in the national air space.

NTSB Most Wanted

1) I would re-rank the NTSB's top 5 improvements for 2016 as follows:

  1. Prevent loss of control in flight
  2. Fatigue related incidents
  3. Reducing distractions
  4. Medical Fitness
  5. Cockpit Image Recorders
   I chose preventing the loss of control in flight as my most important because next to the common sense factor in it, the article by Bellamy (and on the ntsb website) states that loss of control in flight has been the cause of over 40% of accidents in the GA sector from 2011-2011 (Bellamy 2016/ntsb.gov). A reason I think that this statistic is so large is because some of these pilots fly maybe once or twice a year enough to keep themselves current and to take the ol' plane out when there isn't a cloud in the sky. I think the lack of practiced recurrent training by the FAA could be to blame here considering that a private pilot is required to complete a flight review once every 24 calendar months and needs 3 takeoffs and landings in the past 90 days to carry passengers. In my opinion that doesn't seem like much especially if you're just coasting by on those bare minimums to keep yourself current. I understand this isn't the issue for all of these accidents, but when you factor in brand new student/private pilots and sports pilots who only fly a couple times a year the lack of experience can be a cause to these accidents.

  The second most important is reducing fatigue related incidents, although it has improved a whole lot since the Colgan accident and before. Fatigue will always be that sleeping demon waiting to be triggered and with the pressures that some companies put on their pilots and the workloads that are taken on, it's an issue that should maintain atop the list.

   Reducing distractions is my number 3, but it's a close decision between that and fatigue. I think distractions have become increasingly worse through these past 6 years with the technology boom. I mean nowadays part 121 carriers equip their pilots with some form of tablet to help reduce workload. It's easy to see how having a tablet or even your cellphone in the cockpit for a long trip or during a period of low work activity can lead to distractions. The use of tablets has become almost necessary for 121 operators and although the FAA has created a final rule against using smartphones or laptops while operating the aircraft, it'll be interesting how the tablet is considered.

   Fourth I chose medical fitness because we all are aware of the tests and examinations pilots must go through to maintain their medical certificates. The article by Bellamy mentioned an increase of positive tests for over-the-counter sedative medication and I think that could contribute to fatigue incidents. The increase of these sedative medications doesn't bode well for the NTSB because ever since the GermanWings suicide last year they've been on high alert for symptoms of depression. Those kind of mental issues can be tough to pinpoint though because without monitoring the person everyday and intensely, you can't tell someone is depressed. I think the FAA or pilot world could improve on their mental evaluations of employees, but I don't see it as an issue that is pressing.

   Lastly I have Cockpit image recorders at the bottom of my list. The reason being is that in the cockpit there is already a flight data recorder that reads the inputs made on the flight controls and can paint the story of what happened in the accident. With actual image recording in the cockpit not only seems invasive to the pilots, but further cements the idea/theory that accident analyzers have come up with using the FDR. I think it's an economic investment not worth the consideration due to it's risk if images/video were to get leaked and the fact that it's redundant in nature since the flight data recorder exists as well. Not only do I rank this item last on my most wanted list but I would even go as far to say that it doesn't need to be on the list at all.

   Now an item that has been left off the list which I think should be included is automation dependency. For the most part (in EMU's and WMU's  pilot programs) they start the student pilots off with aircraft equipped with a glass cockpit. Now they try and teach their students to focus on the gauges and fly the plane, but as a pilot gets more experienced in the glass cockpit, it becomes much easier to get dependent on all of the capabilities that it has to offer. It's a great technological advancement and has reduced the workload of  the pilot immensely, but there have been plenty of incidents (think Air France 447 accident) where the pilots completely shut down and forgot how to fly the plane when the automation stopped working.

  I think the FAA will respond to the reducing distractions and medical fitness the most. The reason I think this is because they've already addressed the distractions one a little bit with that final rule created for 121 operators in April of 2014. I think they'll address the medical fitness one because it affects the public image of aviation the most. Plus if they're able to reduce that amount of positive tests for over-the-counter sedative medication it could go hand in hand with reducing fatigue in flight.

Aviation Organizations

   One of the groups I look to be apart of when I am engaged in my career is the ADF or Airline Dispatcher Federation. Another organization that has me very interested once I begin my career path is the EAA or Experimental Aircraft Association.
   What I like about ADF is that it is a volunteer organization and isn't a labor organization. It's also the only national organization that represents the dispatch profession. In the industry the ADF works on the professional image and development of the aircraft dispatch career. They also represent over 100 aerospace companies so it isn't strictly for dispatchers who work at the airlines and are non-unionized. The EAA is crucial to the aviation field because their members continue to exceed the boundaries of  experimental aircraft and the rise of ultralights. They also contribute back to the industry by offering a ton of scholarships and learning workshops for pilots of all skill level. They have a large presence at Oshkosh and if an organization is big at Oshkosh you know they're helping the general aviation area.
   In our profession it's huge to be apart of an organization because you never know who you're going to meet. Our industry is small so meeting people is just as important if not equally important than gathering the hours and experience in the industry. They also help get your name out there and if you participate in events they can leave a lasting impression on your aviation peers. Not only are they good for networking but they can continue to provide learning experiences well after you end your schooling. Considering knowledge is power this is a great opportunity to further your aviation intelligence while strengthening your reputation in the field.
