Air traffic control Essay Example for Free

Air traffic control Essay Situation 1: Adapted from WAFBLA â€Å"Everyone Else Does It! † Ethics Project You have been struggling in your Engineering Models class. The content does not come easily, so you have put in countless hours to understand and do the assignments. There is another student who breezes through the assignments, getting high marks for the work he turns in. You know for a fact that he has used his college-aged cousin to do some of the assignments for him. You don’t know how many assignments were turned in this way, but you are certain that he, in fact, did not do all the work. Your frustration increases over the last assignment that you worked overtime on, but did poorly. Of course, this other student scored well on the same assignment. You drop the teacher an anonymous note about the implied cheating on the part of this other student. Questions: 1) What do you believe are the ethical issues related to this situation? Not being prepared to turn in the assignment. Trying to use someone elses work as your own. | 2) Write an argument supporting the actions taken. Be sure to tie your response to one of the ethical frameworks discussed. This is the rights approach as you are telling the teacher that another student is not turning in his actual work. This will make the challenge of the assignment fair for everyone. | 3) Write an argument against the actions taken. Be sure to tie your response to one of the ethical frameworks discussed. You should just let the other student do what he wants to and tell him that he won’t be able to get help when he does the exam. | 4) Were you in this situation, what would your response be? Why? I would also tell the teacher that he is cheating so that it would be fair for everyone who turns in their homework. | Situation 2: Occidental Engineering Author: Michael McFarland, S. J. Wayne Davidson is a software engineer in the aerospace division of Occidental Engineering, a large engineering firm. For the past two years he has been working as a test engineer for Operation Safe Skies, a project to build a prototype of the next generation air traffic control system. This project, which is funded by a contract from the Federal Aviation Agency (FAA), is a very important one for Occidental. With all the cutbacks in defense spending, the aerospace division has been losing business. The Safe Skies project has provided much needed business, and could lead to a much larger contract if successful. Mindful of its strategic importance, the company had bid very aggressively for the original contract. In fact they had low-balled it, bidding less than it would take to do the work properly. They felt that was the only way they could beat out their competitors, who were just as hungry for the work. Because of their somewhat shaky financial position, the company was not willing to take a loss on the project, so the project has been underfunded and understaffed. Nevertheless those working on the project have made a heroic effort, working eighteen hour days seven days a week to meet the deadline, because they know how much it means to the company, not to mention their own jobs. They are now very close to success. A version of the prototype has been completed and turned over to Wayne for testing. He has run extensive simulations on it and found that it works as it should except for one little problem: when there are too many aircraft in the system, it will sometimes lose track of one or more of them. The forgotten aircraft will simply disappear from the screen, there will be no trace of it anywhere, and it will be ignored by all of the collision avoidance and other safety tests. Wayne has been working with the software designers to identify the cause of the problem, and they have traced it to a subtle error in memory allocation and reuse. They are confident that they can fix it, but it will take a month or more to do the redesign, coding and testing. Wayne meets with his boss, Deborah Shepherd, the project manager, to discuss the implications. She tells him that what he is asking for is impossible. The contract requires that the company deliver a fully certified, working version of the software in three days for system integration and test. The government has developed a new, get-tough policy on missed deadlines and cost overruns, and Occidental is afraid that if they miss this deadline, the government will make an example of them. They would be subject to fines and the loss of the remainder of the prototype contract; and they might not be allowed to bid on the contract for the full system. This would have a devastating effect on the aerospace division, resulting in thousands of lost jobs. They consider whether they can do a quick patch to the software before turning it over, but Wayne adamantly refuses to release any code that has not been tested thoroughly. There is always a chance that the patch would interact with some other part of the program to create a new bug. Then well have to deliver the software as is, Deborah says. I cant jeopardize this project or the jobs of my people by missing that deadline. We cant do that! exclaims Wayne. Thats like delivering a car with defective brakes. Dont worry, Deborah reassures him. We have contacts in the FAA, so we know their testing plans. They will do a lot of simulations to make sure the software works with the hardware and has all the functionality in the specs. Then they will do live tests, but only at a small airport, with a backup system active at all times. There is no way they will overload the system in any of this. After that they will have some change requests. Even if they dont, we can give them an updated version of the program. We can slip the bug fix in there. They will never see the problem. Even if they do, we can claim it was a random occurrence that would not necessarily show up in our tests. The important thing is no one is in any danger. Maybe they wont find the bug, but I know its there. I would be lying if I said the system passed all the necessary tests. I cant do that. Anyway, it would be illegal and unprofessional. You can certify that it is safe, because it is, the way they are going to use it. And so he does. In the end Wayne signs off on the software. It is delivered to the FAA and makes it through all the preliminary tests, including live tests at a small airport in the Midwest. As a result of these tests, the FAA requests some changes in the user interface, and when Occidental delivers the new software it includes a robust solution to the problem of the disappearing aircraft. No one outside of Deborahs group ever learns of the problem. In fact Occidentals success with the prototype leads to major contracts for air traffic control software, giving much-needed business to the aerospace division. This saves hundreds of jobs, and allows the company to add hundreds more. Wayne Davidson, however, takes early retirement once the prototype project is finished, in order to write a book on software testing. He feels that the book should have a chapter on ethics, but he can never bring himself to write it. Questions: 1) What do you believe are the ethical issues related to this situation? Lying about a completed project when it isn’t. | 2) Write an argument supporting the actions taken. Be sure to tie your response to one of the ethical frameworks discussed. There was no productive way to get all of the project done, so they had to give what they had. | 3) Write an argument against the actions taken. Be sure to tie your response to one of the ethical frameworks discussed. It wasn’t a good choice because they didn’t tell the company that the project wasn’t finished and handed them an incomplete project. | 4) Were you in this situation, what would your response be? Why? I would ask for more people to help so we could get the project done on the day its due and assign each person a different part to do. |
