1 Lesson 1: Introduction to Learning Aviation Science by: Alex Stackhouse

2 Important Info. Scientists believe that the brain recalls new information more efficiently if the new information is associated in one of these ways: Acoustic coding: information associated with a sound. Visual coding: information associated with an image. Semantic coding: information associated with meaning. Semantic coding is improved by associating new information with previous knowledge. To succeed in online learning, especially in aviation learning, you should devote several blocks of time each week to study the course. Make sure to practice the information you learn from the course on flight simulators to get more of a realistic experience with your new knowledge. There are many different types of pilot certificates that allow different pilots to do different tasks. Donʼt forget that the internet can be an excellent resource for aviation information. Studies of online courses show that the more you interact with your instructors and fellow students, the more meaningful this course will be.

3 Question #1 How many pilots are there in the United States? 140, , million

4 Question #2 The Civil Air Patrol was founded in

5 Question #3 The Federal Aviation Administration... Regulates aviation in the U.S. Certifies pilots, mechanics, and airlines. Directs air traffic control activities in the U.S. All of the above

6 Question #4 An important goal of the EAA Young Eagles Program is to... Give the opportunity to fly to more than one million young people. Get more young people involved in aviation. Develop more individual potential through flight. All of the above.

7 Answers 1.) 580,000 2.) ) All of the above 4.) All of the above

8 Lesson 2: The Basics of Flight

9 Important Info. In the 1700s, the French discovered the hot air balloon and made the first flight possible. Further work in the 1800s on gliders by the British scientist, Sir George Cayley, laid the foundation for more practical application of flying. A German engineer, Otto Lilienthal, further perfected glider designs with the idea of achieving powered flight at some time, but as with many other aviation pioneers, he was killed during a glider flight. It was two Ohio brothers, Orville and Wilbur Wright, who had the patience and skill to design the first successful airplane capable of heavier-than-air, powered, sustained, controlled, flight. The first passengers carried on a known flight were a sheep, a rooster, and a duck carried on board a balloon ride being demonstrated to the French King Louis XVI and Marie Antoinette by the French Montgolfier brothers on September 19, In 1894, Sir Hiram Maxim of Britain lifted a huge steam-powered machine into the air, but it quickly crashed. In the 1700s, the Swiss scientist Daniel Bernoulli discovered that speeding up fluid through a constriction device called a venturi tube caused the fluidʼs resulting pressure to decrease. Air Density, Velocity, and Surface area all effect the lift of an aircraft.

10 Important Info. Cont. Generally, the higher the angle of attack, the greater the lift produced. A spin occurs when an aircraft stalls with one wing stalled more than the other. It is important to remember that for a spin to occur, the wings must be stalled first, one more than the other. Leading edge refers to the front edge of the airfoil, where the air separates. The trailing edge is at the rear of the airfoil. Camber comes from the Latin word to change and refers to the curved shape of the upper and lower airfoil. Chord is an imaginary straight line that connects the leading edge to the trailing edge of a cross section of an airfoil. Angle of Attack is the angle between the wing chord line and the flightpath.

11 Question #1 This father and son made wings of wax and feathers to escape the island of Crete in a famous Greek myth: Leonardo and Michelangelo Daedalus and Icarus Homer and Alexander

12 Question #2 Who made the first powered flight? The Wright Brothers Sir Hiram Maxim Otto Lienthal

13 Question #3 The following are examples of airfoils, except: An airplane wing A helicopter rotor blade A propeller The aircraft landing gear

14 Question #4 The empennage on a light training aircraft includes these basic airfoil shapes: The horizontal stabilizer The vertical stabilizer The rudder The elevator All of the above

15 Answers 1.) Daedalus and Icarus 2.) Sir Hiram Maxim 3.) The aircraft landing gear 4.) All of the above
