Weather and Aviation: How Does Weather Affect the Safety and Operations of Airports and Aviation, and How Does FAA Work to Manage Weather-Related Effects?
Kulesa 1 Weather and Aviation: How Does Weather Affect the Safety and Operations of Airports and Aviation, and How Does FAA Work to Manage Weather-related Effects? By Gloria Kulesa Weather Impacts On Aviation In addition, weather continues to play a significant role in a number of aviation Introduction accidents and incidents. While National Transportation Safety Board (NTSB) reports ccording to FAA statistics, weather is most commonly find human error to be the the cause of approximately 70 percent direct accident cause, weather is a primary of the delays in the National Airspace contributing factor in 23 percent of all System (NAS). Figure 1 illustrates aviation accidents. The total weather impact that while weather delays declined with overall is an estimated national cost of $3 billion for NAS delays after September 11th, 2001, delays accident damage and injuries, delays, and have since returned to near-record levels. unexpected operating costs. 60000 50000 40000 30000 20000 10000 0 1 01 01 0 01 02 02 ul an 01 J ep an 02 J Mar May S Nov 01 J Mar May Weather Delays Other Delays Figure 1.

Ff 89/6 Copy
$3 vol libre • free flight 6/89 Dec - Jan POTPOURRI SAC was informed by Sport Canada on the 10th of July that we are not eligible for funding for 1989-90 and until further notice. Thus we are now totally on our own. The average yearly grant from 1979 to 1988 in 1989 dollars was $14,000, or $16 per person. Perhaps it’s a good thing as planning in an atmosphere of doubt is not conducive to good health and efficient use of funds. The cutback was not unexpected and steps were taken early on to ease the effects of this loss of revenue. Imaginative planning in our small store and a good response from our members through the use of the “Soaring Stuff” inserts resulted in in- creased sales. We will also receive higher than projected invest- ment income essentially due to careful cash management and short-term interest rates, which have remained higher for longer than generally expected. In addition, a small gain in projected receipts from an unexpected increase in membership – now at 1423 – which is the first time since 1982 that we have passed 1400. Total expenditures should come in well below budget projection, primarily as a result of scaling back meetings and travel expenditures. On balance it seems fair to say that a combination of some tight fistedness on the expenditure side and a bit of luck on the revenue side will leave SAC in a financially stronger position than was expected at the beginning of the season, despite the cutting off of govern- ment funding. -

Efficient Light Aircraft Design – Options from Gliding
Efficient Light Aircraft Design – Options from Gliding Howard Torode Member of General Aviation Group and Chairman BGA Technical Committee Presentation Aims • Recognise the convergence of interest between ultra-lights and sailplanes • Draw on experiences of sailplane designers in pursuit of higher aerodynamic performance. • Review several feature of current sailplanes that might be of wider use. • Review the future for the recreational aeroplane. Lift occurs in localised areas A glider needs efficiency and manoeuvrability Drag contributions for a glider Drag at low speed dominated by Induced drag (due to lift) Drag at high ASW-27 speeds Glider (total) drag polar dominated by profile drag & skin friction So what are the configuration parameters? - Low profile drag: Wing section design is key - Low skin friction: maximise laminar areas - Low induced drag – higher efficiencies demand greater spans, span efficiency and Aspect Ratio - Low parasitic drag – reduce excrescences such as: undercarriage, discontinuities of line and no leaks/gaps. - Low trim drag – small tails with efficient surface coupled with low stability for frequent speed changing. - Wide load carrying capacity in terms of pilot weight and water ballast Progress in aerodynamic efficiency 1933 - 2010 1957: Phoenix (16m) 1971: Nimbus 2 (20.3m) 2003: Eta (30.8m) 2010: Concordia (28m) 1937: Wiehe (18m) Wooden gliders Metal gliders Composite gliders In praise of Aspect Ratio • Basic drag equation in in non-dimensional, coefficient terms: • For an aircraft of a given scale, aspect ratio is the single overall configuration parameter that has direct leverage on performance. Induced drag - the primary contribution to drag at low speed, is inversely proportional to aspect ratio • An efficient wing is a key driver in optimising favourable design trades in other aspects of performance such as wing loading and cruise performance. -
Preventive Maintenance
Maintenance Aspects of Owning Your Own Aircraft Introduction According to 14 CFR Part 43, Maintenance, Preventive Maintenance, Rebuilding, and Alteration, the holder of a pilot certificate issued under 14 CFR Part 61 may perform specified preventive maintenance on any aircraft owned or operated by that pilot, as long as the aircraft is not used under 14 CFR Part 121, 127, 129, or 135. This pamphlet provides information on authorized preventive maintenance. How To Begin Here are several important points to understand before you attempt to perform your own preventive maintenance: First, you need to understand that authorized preventive maintenance cannot involve complex assembly operations. Second, you should carefully review 14 CFR Part 43, Appendix A, Subpart C (Preventive Maintenance), which provides a list of the authorized preventive maintenance work that an owner pilot may perform. Third, you should conduct a self-analysis as to whether you have the ability to perform the work satisfactorily and safely. Fourth, if you do any of the preventive maintenance authorized in 14 CFR Part 43, you will need to make an entry in the appropriate logbook or record system in order to document the work done. The entry must include the following information: • A description of the work performed, or references to data that are acceptable to the Administrator. • The date of completion. • The signature, certificate number, and kind of certificate held by the person performing the work. Note that the signature constitutes approval for return to service only for work performed. Examples of Preventive Maintenance Items The following is a partial list of what a certificated pilot who meets the conditions in 14 CFR Part 43 can do: • Remove, install, and repair landing gear tires. -

RIGHT FLIGHT Objectives The students will: Construct a flying model glider. Determine weight and balance of a glider. Standards and Skills Science Science as Inquiry Physical Science Science and Technology Unifying Concepts and Processes Science Process Skills Observing Measuring Collecting Data Inferring Predicting Making Models Controlling Variables Mathematics Problem Solving Reasoning Prediction Measurement Background On December 17, 1903, two brothers, Wilbur and Orville Wright, became the first humans to fly a controllable, powered airplane. To unravel the mysteries of flight, the Wright brothers built and experimented extensively with model gliders. Gliders are airplanes without motors or a power source. 52 Aeronautics: An Educator’s Guide EG-2002-06-105-HQ Building and flying model gliders helped the Wright brothers learn and understand the importance of weight and balance in air- planes. If the weight of the airplane is not positioned properly, the airplane will not fly. For example, too much weight in the front (nose) will cause the airplane to dive toward the ground. The precise balance of a model glider can be determined by varying the location of small weights. Wilbur and Orville also learned that the design of an airplane was very important. Experimenting with models of different designs showed that airplanes fly best when the wings, fuselage, and tail are designed and balanced to interact with each other. The Wright Flyer was the first airplane to complete a controlled takeoff and landing. To manage flight direction, airplanes use control surfaces. Elevators are control surfaces that make the nose of the airplane pitch up and down. A rudder is used to move the nose left and right. -
Evolving Green Aviation Transport System: a Hoilistic Approah to Sustainable Green Market Development
American Journal of Climate Change, 2012, 1, 164-180 http://dx.doi.org/10.4236/ajcc.2012.13014 Published Online September 2012 (http://www.SciRP.org/journal/ajcc) Evolving Green Aviation Transport System: A Hoilistic Approah to Sustainable Green Market Development A. N. Sarkar International Business & Research, Asia-Pacific Institute of Management, New Delhi, India Email: [email protected] Received June 24, 2012; revised July 25, 2012; accepted August 10, 2012 ABSTRACT Aviation is one of the fastest growing industries as well as transportation modes in the world. Global aviation contrib- utes about 2% of global greenhouse gas emissions and supports 8% of the world economic activity in terms of GDP. With the phenomenal growth in air trafficking by the national and international airliners the total carbon space available for flying is getting progressively diminished and the consequential emission levels are also becoming alarming over passage of time. The paper describes the concept of evolution of Green Transport system with focus on manufacturing of green aircraft and sustainable green marketing involving green supply chain. This entails introduction of New and innovative technologies, including aircraft designing, improving operational efficiency, air traffic control & monitoring etc; combined with emission mitigation efforts towards sustainable growth of the industry, can make enormous im- provements in emission control and reduction in a planned and system-based manner. These integrated approaches are proposed to be used to harmonize the systems and processes that can essentially constitute the suggested framework of the Green Aviation Transport system. The paper, inter alia, discusses various conceptual, strategic, technological and economic and environmental dimensions of the Green Aviation transport system with focus on creating new Green Marketing opportunities for the aviation industry in future. -

Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’S Note to Flightlab Students
Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’s Note to Flightlab Students The collection of documents assembled here, under the general title “Unusual Attitudes and the Aerodynamics of Maneuvering Flight,” covers a lot of ground. That’s because unusual-attitude training is the perfect occasion for aerodynamics training, and in turn depends on aerodynamics training for success. I don’t expect a pilot new to the subject to absorb everything here in one gulp. That’s not necessary; in fact, it would be beyond the call of duty for most—aspiring test pilots aside. But do give the contents a quick initial pass, if only to get the measure of what’s available and how it’s organized. Your flights will be more productive if you know where to go in the texts for additional background. Before we fly together, I suggest that you read the section called “Axes and Derivatives.” This will introduce you to the concept of the velocity vector and to the basic aircraft response modes. If you pick up a head of steam, go on to read “Two-Dimensional Aerodynamics.” This is mostly about how pressure patterns form over the surface of a wing during the generation of lift, and begins to suggest how changes in those patterns, visible to us through our wing tufts, affect control. If you catch any typos, or statements that you think are either unclear or simply preposterous, please let me know. Thanks.
