Relationship Between Airspeed, Lift and Drag ( Continuity Equation)
Explain what affect an increase in airspeed has on lift, as well as on drag, both induced and
parasite. Include in your answer the “why” for your answer. Consideration should be given to the
lift and drag equation, Bernoulli, Newton, The Continuity Equation, and any other concept
discussed in the text.
Select an incident that happened in the past and summarize the investigation of the accident. Now, assume you are the lead investigator in a future accident involving an aircraft, what steps will you follow until you conclude the investigation. Assume the accident will be as a result of a mid-air collision with a UAV (20-25 pages, Report Format with table of contents). Also use charts, diagrams, and any other graphic that may enhance understanding of your report.
Maintenance and Reliability
For this activity, you will assume the role of an aviation maintenance manager.
As the aviation maintenance manager, you are responsible for all maintenance actions and for maintaining
aircraft in a serviceable condition.
For this assignment, conduct research to identify a current aviation maintenance challenge/issue. In your briefing, you will identify the maintenance issue and provide a maintenance strategy to correct the maintenance issue.
Your presentation must include a minimum of five, but no more than eight, slides not including the title slide or reference slide, have embedded audio, and include speaker notes.
Keep in mind that as a minimum your presentation must:
Identify a current aviation maintenance issue of your choosing.
Explain the impact of the maintenance issue.
Define how scheduled maintenance cycles can be used as part of your strategy in addressing
the issue.
Determine and support the role of a reliability program in ensuring that your strategy corrects the
issue.
Refer to Presentation Assignment Guidance for more information and review the rubric for this

Importance of additive Manaufacturing in Improving Production of a Product (In this case, Jet Engine Turbine Blades)
Instructions
Here are the guidelines for your course paper this semester. I want this paper to add value to your career, using additive, and the most important thing to learn is how to adapt design and engineering thinking to take advantage of 3D printing. We refer to this adaptation process as Designing for Additive Manufacturing or DfAM. Therefore the paper topic is DfAM.
Paper Topic: Design for Additive Manufacturing (DfAM)
Formatting: 10 pages, without images.
Double spacing, 3/4 inch margins.
Arial or Times New Roman font, 11 point.
Deliver it as a Microsoft Word document please
Background: Additive Manufacturing makes complexity free (sort of), so take advantage of it. Curved surfaces, pockets and undercuts are very expensive to produce in subtractive manufacturing, but relatively “free” in AM. How can you take advantage of “free” complexity in a product that you choose from your local environment? What are the advantages, technical and economic, of choices you would make in redesigning your chosen product.
Select an object or product that interests you, perhaps something from your work, research or a class. Choose something that makes sense to produce using AM compared to other methods of production manufacturing (subtractive or formative). It could be an assembly of more than one component. Discuss why you think this product could be improved using AM, and how. Provide images or drawings of your object(s), with a few representative annotations that show what you think are “critical” dimensions.
Discuss user/customer requirements for the object(s) you chose. What color, surface finish, durability/duty cycle, temperature, chemical resistance, etc. are you envisioning will be required for your object(s)?
***VERY IMPORTANT *** Consider how you would design or redesign this object to take best advantage of AM. Discuss how could and would take advantage of the power of additive manufacturing in this object. Be specific – what features could be made better and how? Which of the requirements you listed above would be better addressed because you have additive?
What would you design differently if you have AM as a tool? How did you think and design differently to take advantage of AM? Be specific.
Which AM process(es) would be better or not for your design/object? Select an additive process for your object. Discuss your thought process – why did you choose this process? How would you create the object using the process you have selected, considering the strengths and limitations of AM in producing your object? What tradeoffs will you have to accommodate because of your selection? What orientation and scale trade-offs do you consider important for the particular AM process you selected and why? What material would you choose and why?
How will you define “quality” for your object? What parameters of quality do you think will matter most for your object? Consider these parameters as quality requirements. How will you validate the quality of your object according to these requirements when its produced?
***VERY IMPORTANT*** – What are the cost trade-offs you will make using AM to produce your object vs. another method of manufacture? What types of post-processing will you have to accomplish to deliver your object in its final form (per requirements above)? What does “complexity is free” mean with respect to your object(s), or doesn’t it?

A road must be designed to cross some railway tracks. The approaches are both flat, with no horizontal curvature and are at the same level. The vertical alignment comprises a level approach at ground level, a sag curve, a single crest curve over the railway, and a sag curve returning to ground level. The maximum permitted gradient is 6%, and lengths of this gradient may be used between the crest and sag curves if required. The railway tracks are at ground level and are [W] metres wide. The road alignment must be at least [h]metres above ground level over this entire width.

Advantages of Arbitration
Faster than litigation in court
A time limit can be placed on the length of the process
Cost – cheaper and more flexible
Informal – more commercial and less formal than court
Confidentially – unlike court rulings, arbitration proceedings and arbitral awards are confidential.
Disadvantages
No appeals, the arbitration decision if final. Even if one party feels that the outcome was unfair, unjust or biased they cannot appeal it
Evidence – rules of evidence may prevent some evidence from being considered by a judge or a jury, but an arbitrator may consider that evidence, So an arbitrators decision…
Expert determination is described as a procedure by which the parties to a dispute appoint an independent and neutral expert to determine the dispute in private. Like arbitration, it allows trade secrets and other sensitive information to be kept out of the public domain. The expert is a person with specialist or technical knowledge relevant to the dispute. Their experience and professional knowledge are expected to help solve the dispute.
Expert determination
Provides cost efficient resolution for dispute and problems, confidential and private.
Controlled by parties so scope of jurisdiction and terms of reference come from contract with parties so is unable to award costs unless the contracts state so.
Knowledge and expertise?
No legal mechanism?
Right or wrong? ( see johns wood )
