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.

AMA FPG-9 Glider OBJECTIVES – Students Will Learn About the Basics of How Flight Works by Creating a Simple Foam Glider
AEX MARC_Layout 1 1/10/13 3:03 PM Page 18 activity two AMA FPG-9 Glider OBJECTIVES – Students will learn about the basics of how flight works by creating a simple foam glider. – Students will be introduced to concepts about air pressure, drag and how aircraft use control surfaces to climb, turn, and maintain stable flight. Activity Credit: Credit and permission to reprint – The Academy of Model Aeronautics (AMA) and Mr. Jack Reynolds, a volunteer at the National Model Aviation Museum, has graciously given the Civil Air Patrol permission to reprint the FPG-9 model plan and instructions here. More activities and suggestions for classroom use of model aircraft can be found by contacting the Academy of Model Aeronautics Education Committee at their website, buildandfly.com. MATERIALS • FPG-9 pattern • 9” foam plate • Scissors • Clear tape • Ink pen • Penny 18 AEX MARC_Layout 1 1/10/13 3:03 PM Page 19 BACKGROUND Control surfaces on an airplane help determine the movement of the airplane. The FPG-9 glider demonstrates how the elevons and the rudder work. Elevons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control). Thus, elevons at the wing trailing edge are used for pitch and roll control. They are frequently used on tailless aircraft such as flying wings. The rudder is the small moving section at the rear of the vertical stabilizer that is attached to the fixed sections by hinges. Because the rudder moves, it varies the amount of force generated by the tail surface and is used to generate and control the yawing (left and right) motion of the aircraft. -

Glider Handbook, Chapter 2: Components and Systems
Chapter 2 Components and Systems Introduction Although gliders come in an array of shapes and sizes, the basic design features of most gliders are fundamentally the same. All gliders conform to the aerodynamic principles that make flight possible. When air flows over the wings of a glider, the wings produce a force called lift that allows the aircraft to stay aloft. Glider wings are designed to produce maximum lift with minimum drag. 2-1 Glider Design With each generation of new materials and development and improvements in aerodynamics, the performance of gliders The earlier gliders were made mainly of wood with metal has increased. One measure of performance is glide ratio. A fastenings, stays, and control cables. Subsequent designs glide ratio of 30:1 means that in smooth air a glider can travel led to a fuselage made of fabric-covered steel tubing forward 30 feet while only losing 1 foot of altitude. Glide glued to wood and fabric wings for lightness and strength. ratio is discussed further in Chapter 5, Glider Performance. New materials, such as carbon fiber, fiberglass, glass reinforced plastic (GRP), and Kevlar® are now being used Due to the critical role that aerodynamic efficiency plays in to developed stronger and lighter gliders. Modern gliders the performance of a glider, gliders often have aerodynamic are usually designed by computer-aided software to increase features seldom found in other aircraft. The wings of a modern performance. The first glider to use fiberglass extensively racing glider have a specially designed low-drag laminar flow was the Akaflieg Stuttgart FS-24 Phönix, which first flew airfoil. -

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. -

The Wright Brothers Played with As Small Boys
1878 1892 The Flying Toy: A small toy “helicopter”— made of wood with two twisted rubber bands to turn a small propeller—that the Wright brothers played with as small boys. The Bicycle Business: The Wright brothers opened a bicycle store in 1892. Their 1900 experience with bicycles aided them in their The Wright Way: investigations of flight. The Process of Invention The Search for Control: From their observations of how buzzards kept their balance, the Wright brothers began their aeronautical research in 1899 with a kite/glider. In 1900, they built their first glider designed to carry a pilot. Wilbur and Orville Wright Inventors Wilbur and Orville Wright placed their names firmly in the hall of great 1901 American inventors with the creation of the world’s first successful powered, heavier-than-air machine to achieve controlled, sustained flight Ohio with a pilot aboard. The age of powered flight began with the Wright 1903 Flyer on December 17, 1903, at Kill Devil Hills, NC. The Wright brothers began serious experimentation in aeronautics in 1899 and perfected a controllable craft by 1905. In six years, the Wrights had used remarkable creativity and originality to provide technical solutions, practical mechanical Birthplace design tools, and essential components that resulted in a profitable aircraft. They did much more than simply get a flying machine off the ground. They established the fundamental principles of aircraft design and engineering in place today. In 1908 and 1909, they demonstrated their flying machine pub- licly in the United States and Europe. By 1910, the Wright Company was of Aviation manufacturing airplanes for sale. -

Introduced in April of 1944, the German Messerschmitt Me 262 was the world’s first jet-powered fighter aircraft. Nicknamed the Schwalbe (Swallow), its twin turbojets were the first ever to be mass produced. The result of innovative research and engineering prowess, the Me 262 could fly faster than its piston engine rivals and was heavily armed. Around 1,400 were built, an insignificant number when compared with the total production runs of almost 34,000 for the Messerschmitt Bf 109 and more than 20,000 for Great Britain’s Supermarine Spitfire. Too few Me 262s arrived too late to change the outcome of World War II. -

A Brief History of Aviation-Part I With Emphasis on American Aviation Faster, Higher, Further! OLLI Fall 2012 Session L805 Mark Weinstein, Presenter 1 Full Disclosure • Currently a Docent at both Smithsonian Air and Space Museums • Retired from the Air Force-Active duty and Reserve • Electrical Engineer • 104 hours flying a Piper Tri-Pacer Wanted Caution: Long Winded Stories Reward: Info and Enjoyment 2 Ask Questions ― ? As we fly along ? 3 Anyone here a Pilot? 4 Historical Perspective • Historians and economists consider Aviation and follow on Space Endeavors to be one on the key transitional events of the 20 th Century. Aviation is more than the sum of it parts and it drove and was driven by: – Expanding technologies – Aeronautical engineering and research – Advance in manufacturing – Industrial development and national industrial policies – New materials – Warfare needs and drivers – Political actions – Transportation needs, investments and subsidies – Large scale population migration – Adventure, exploration, vision and finally fantasy. 5 Starting Off on a Positive Note • "Heavier-than-air flying machines are impossible“ -- Lord Kelvin, President, Royal Society, 1895. • "Airplanes are interesting toys but of no military value“ -- Marshal Ferdinand Foch, Professor of Strategy, Ecole Superieure de Guerre, France, 1911 -- Commander of all Allied Forces, 1918 • "Everything that can be invented has been invented" -- Charles H.
