Ethics and Morality



Ethical Use of UAS Systems for War
            Many people think that the use of unmanned systems for the taking of human life in warfare is unethical because it does two things;
1.      Removes all risk of injury or death from the operator
2.      Further turns war into a process, removing the humanity from the situation, and making it easier to engage in warfare

While this is all true it ignores a key point; war was never fair and many weapons that are now commonplace and considered “fair” were at one time considered unethical. A few hundred years ago, the bow and arrow could be considered unethical. It meets both of the above criteria, removing the operator from almost all risk of injury or death and making it easier to wage war. Many people consider sniper rifles to be in the same category because for the most part, they yet again meet all of the above criteria.
One could make the argument that just about any weapon that gave its user an advantage was considered unethical at the time, until everybody acquired the technology and the playing field was again level.
In this sense, UAS systems are no different. What makes UAS unique is the integration of AI. For the first time in human history it is possible to give the decision to kill to the machine. This is the key issue at hand. Should non-humans be given the task of conducting war against humans?
The answer is no. Efficiency should never be favored over reflection, careful judgment, and sometimes even mercy just for the sake of mercy. All humans strive to make even the most inhumane acts, war, the death penalty, imprisonment, as humane as possible while still accomplishing the goal at hand. This means attempting to treat others as you yourself would want to be treated to the best of your ability. Artificial intelligence is not capable of this, at least not yet.
We know that in war we have to kill, but we also know that we can do it as humanely as possible. This is the reason that many weapons that cause undue suffering, such as chemical weapons, are banned by certain treaties and agreements. Most combatants would rather take life as painlessly as possible or not at all if they can avoid it.
There are however, people who do seek to cause undue suffering. This is basically the entire focal point of any terrorist group. To cause terror, which means undue suffering. So is it OK to fight fire with fire in this case? I do not believe so. What makes the good guys “good”, is their desire to do what is right, even in extremely difficult situations. War should not be turned into a “set-it-and-forget-it” process with the use of artificial intelligence.
As usual, the ethics of any situation are never black and white. However, as usual, we could definitely make a better attempt and not crossing the line and behaving like our enemies.

UAS Crew Selection



UAS Crew Selection
Boeing Scan Eagle
            The Boeing Scan Eagle normally requires two people for its operation, a controller to set way points for the system to follow and a payload operator to work the camera. Recently, research has been done in which one pilot was responsible for three aircraft at once (Pappalardo, 2007). This experiment was successful, however since this software is still in the testing phases it is advisable to stick to proven crew configurations.

General Atomics Ikhana
            The Ikhana is a Predator B system that has been re-purposed as a scientific research and test bed aircraft. The Ikhana is currently owned by the National Aeronautics and Space Administration (NASA). The Ikhana is equipped with sensing equipment that is used to measure anomalies in the Earth's atmosphere ("NASA Armstrong...", 2014). This system also typically uses a two man crew, one to pilot the aircraft and one to operate the payload.

Ideal Candidate
            The ideal candidate needs to be someone with the skills, knowledge, and the DESIRE to work on the project. This means that our candidates will need prior experience operating military UAV systems. It also means that a preferable candidate would also have a scientific background of some sort, most likely related to the specific topic at hand. For the Ikhana there are many Predator B crews with more than enough experience to operate the system. Finding a scientific person might not be too hard because the Air Force requires their pilots to be Officers, which means they have at least a bachelor’s degree. This should mean that the chances of finding someone with a scientific background are better.

Qualifications for Operations in the National Airspace System
            Currently the FAA has only issued a notice of proposed rule-making for drones under 55 lbs. The proposal does state that the operator will have to have a drone certificate, much like a pilot license. Also, as of now, the operating agency will need to acquire a Certificate Of Authorization (COA) to operate any drones commercially within the NAS (Nicas & Pasztor, 2013). The current proposed rule-making only concerns ling of sight operations which means permission must be acquired from the FAA to operate beyond-line-of-sight (BLOS).

RISK ASSESSMENT FOR BOEING SCAN EAGLE



Preliminary Hazard List/Analysis for Boeing Scan Eagle Operations
                        Above is the Preliminary Hazard List (PHL) combined with the analysis (PHLA). It shows ten likely hazards to be encountered with Boeing Scan Eagle Operations. The Boeing Scan Eagle is a small track-launched UAV. It was designed by Boeing and Insitu Group to be a low cost autonomous drone that would loiter over battlefields and provide surveillance ("ScanEagle Overview...", n.d.).
            While the launching procedure is fairly standard, the recovery is perform with a Sky-Hook system. The UAV basically catches a wire with its wing and then slides down to the operator on the ground. While this might sound risky but the Scan Eagle has accomplished almost over 600,000 hours of combat flight time with very little losses (Bingen, 2012). With this in mind, a risk level of 5 (with 10 being high risk and 1 being no risk) was assigned because of the severity if the launch or recovery should fail, the system would most likely crash and be destroyed.
            Lost link incidences occur rarely but usually result in the loss of the system so a risk level of 8 was assigned.
            Low visibility is not too much of a problem due to the automation of the system, however poor weather, such as turbulence/thunderstorms can cause the destruction of the aircraft so a risk level of critical was assigned. This can be mitigated by sticking to fair weather days when possible.
            Crew inexperience is an occasional possibility due to the cyclical nature of military operations. This can be overcome with the use of good Crew Resource Management and training.
            Since the ScanEagle is a military system it is likely that new hardware and software will be tested regularly. Test flights are always a dangerous endeavor.  This risk can be mitigated through preparation, research, and keeping each test flight short and focused on one test subject at a time.










            RISK ASSESSMENT TOOL
            Above is the risk assessment tool that can be used to determine the level of risk involved with each flight of the Boeing ScanEagle system. Some situations are simple yes or no decisions as far as the level of risk is concerned while others have varying degrees of severity in between. For instance, turbulence isn't necessarily that bad if it is light, and doesn't become a big problem until it is moderate to heavy. Visibility problems won't necessarily cancel a flight either. This table is meant to be used as a simple tool to help make the go/no-go decision. If the risk is high, that will have to be weighted against how important the mission is. Sometimes high to severe levels of risk are warranted depending on the operation.
