Ground Lesson Plan. Preflight and control surfaces 2. Otherwise, if the AOA is decreased too fast, the aircraft will descend, and if the AOA is decreased too slowly, the aircraft will climb, As the airspeed varies due to thrust, the AOA must also vary to maintain level flight, At very high speeds and level flight, it is even possible to have a slightly negative AOA, As thrust is reduced and airspeed decreases, the AOA must increase in order to maintain altitude, If speed decreases enough, the required AOA will increase to the critical AOA, Any further increase in the AOA will result in the wing stalling, Therefore, extra vigilance is required at reduced thrust settings and low speeds so as not to exceed the critical angle of attack, If the airplane is equipped with an AOA indicator, it should be referenced to help monitor the proximity to the critical AOA, Some aircraft have the ability to pivot the engines or vector the exhaust, thereby changing the direction of the thrust rather than changing the AOA [Figure 5-4], Drag is the rearward, resisting force caused by disruption of airflow, Drag is the net aerodynamic force parallel to the relative wind, Drag is always a by-product of lift and thrust, Their are two basic types of drag (induced and parasite) with total drag being a combination of the two, In level flight, the aerodynamic properties of a wing or rotor produce a required lift, but this can be obtained only at the expense of a certain penalty, That penalty, induced drag, is inherent whenever an airfoil is producing lift, as AOA increases, induced drag increases proportionally, To state this another way—the lower the airspeed, the greater the AOA required to produce lift equal to the aircraft's weight and, therefore, the greater induced drag. Principles of flight 7. This downwash over the top of the airfoil at the tip has the same effect as bending the lift vector rearward; therefore, the lift is slightly aft of perpendicular to the relative wind, creating a rearward lift component. Laws and Definitions Introduction Before studying aerodynamics it is essential to have a thorough grounding in basic mechanics and any related units of measurement. Title: PRINCIPLES OF FLIGHT 1 PRINCIPLES OF FLIGHT 2 DEFINITIONS 3. PRIVATE PILOT LESSON PLANS: TABLE OF CONTENTS. 4-2 1500 Figure 4-1. You might even want to reference the chart that the class made together. By the end of this lesson the cadet shall be expected to identify the four forces that act upon an aircraft. Induced drag: drag as the direct result of lift—friction of high pressure air meeting low pressure air around an airfoil, In steady straight flight, the sum of all the opposing forces (lift to weight, and thrust to drag) is zero i.e. Students will also be introduced to some of the aerospace pioneers that led the way to begin our The basic principles of flight, which include many elementary physics concepts, can be easily observed in the structure of an airplane. Slow flight 12. a. During this lesson students will have the opportunity to use interactive computer simulations in order to gain a better understanding of some of the factors that afect light through the atmosphere. U.S. Department of Transportation Federal Aviation Administration 800 Independence Avenue, SW Washington, DC 20591 (866) tell-FAA ((866) 835-5322) Mass - Mass is the quantity of matter in a body ; Density - Density is the mass per unit volume. PRINCIPLES : Forces Acting on An Airplane: ... Each of the named of the airfoil is designed to perform a specific function in the flight of the airplane. Through physical experimentation, students will learn about motions and forces, and transfer of energy as they explore the basics behind the four forces of flight. Weight (5 min) 4. Density is affected by several factors: pressure, temperature, and humidity. Any AOA lower or higher than that for L/DMAX reduces the L/D and consequently increases the total drag for a given aircraft's lift. Professional CFI Lesson Plans » Professional CFI Lesson Plans Introduction to Flight. $ 35.00. The weight, speed, and purpose of each aircraft dictate the shape of its airfoil. The principles of flight are the aerodynamics which deals with the motion of air and the forces acting on a body, in our case an aircraft; lift is the most obvious force, as its what we think of as giving an aircraft the ability to fly; thrust, provides a method with which to move the aircraft Objectives: The student should become familiar with the four forces and principles of flight, airfoil designs, stability, controllability, turning tendencies, airplane load factors, and wing tip vortices.

Explore these ideas further in our article Wings and lift. 3. Conversely, as the aircraft is slowed, the decreasing velocity requires increasing the AOA to maintain lift sufficient to maintain flight. In the vicinity of the tips, there is a tendency for these pressures to equalize, resulting in a lateral flow outward from the underside to the upper surface. Fluids take on the shape of their containers. Discuss the four forces of flight and some of the hazards relating to aerodynamics. Pressure - Pressure is the force per unit area.

Describe airfoils and flight 3. It is neither accurate nor useful to assign specific values to the percentage of lift generated by the upper surface of an airfoil versus that generated by the lower surface. The basic principles of flight, which include many elementary physics concepts, can be easily observed in the structure of an airplane. We all know that gravityis a force that pulls everything towards the Earth’s surface. { // This lateral flow imparts a rotational velocity to the air at the tips, creating vortices that trail behind the airfoil, When the aircraft is viewed from the tail, these vortices circulate counterclockwise about the right tip and clockwise about the left tip.

Lesson Overview. 1. 2. … Visit various web sites related to the History of Flight including the NASA UEET Kid Site. As a result of this change, the velocity about the object changes in both magnitude and direction, in turn resulting in a measurable velocity force and direction, AOA is fundamental to understanding many aspects of airplane performance, stability, and control, AoA is the acute angle measured between the relative wind, or flight path and the chord of the airfoil [, Lift created (or reduced in the case of negative AoA) is measured with the, Every airplane has an angle of attack where maximum lift occurs (, The magnitude of the force of lift is directly proportional to the density of the air, the area of the wings, the airspeed, shape, and AoA, Total lift must overcome the total weight of the aircraft, which is comprised of the actual weight and the tail-down force used to control the aircraft's pitch attitude, While the biggest consideration for producing lift involves the air flowing over and under the wing, there is a third dimension to consider, Consider the tip of the airfoil also has an aerodynamic effect, In order to equalize pressure, the high pressure area on the bottom of an airfoil pushes around the tip to the low-pressure area on the top [, This action creates a rotating flow called a tip vortex, or wingtip vortices, This downwash extends back to the trailing edge of the airfoil, reducing lift for the affected portion of the airfoil, Manufacturers have developed different methods to counteract this action, Winglets can be added to the tip of an airfoil to reduce this flow (essentially decrease induced drag), The winglets act as a dam preventing the vortex from forming, Winglets can be on the top or bottom of the airfoil, Another method of countering the flow is to taper the airfoil tip, reducing the pressure differential and smoothing the airflow around the tip, Weight is simply the force of gravity on the aircraft which acts vertically through the, It is the combined load of the aircraft itself, the crew, the fuel, and the cargo or baggage, Weight varies based on load, passengers, and fuel, A Load is essentially the back pressure on the control stick required, the, Opposing lift, as an aircraft is descending, Weight has a definite relationship to lift, This relationship is simple, but important in understanding the aerodynamics of flying, Lift is the upward force on the wing acting perpendicular to the relative wind and perpendicular to the aircraft's lateral axis, Lift is required to counteract the aircraft's weight, In stabilized level flight, when the lift force is equal to the weight force, the aircraft is in a state of equilibrium and neither accelerates upward or downward, If lift becomes less than weight, the vertical speed will decrease, When lift is greater than weight, the vertical speed will increase, Thrust is the forward acting force that opposes drag and propels the airplane forward, It is through excesses or deficits of thrust that accelerations and decelerations can occur, The aircraft will continue to speed up/slow down until thrust again equals drag at which point the airspeed will stabilize, In powered aircraft, thrust is achieved through the powerplant, be it a propeller, rotor, or turbine, With a glider, thrust is created through the conversion of potential energy (altitude) to kinetic energy (airspeed) by pitching toward the ground, This law may be expressed by F = MA (Force equals Mass times Acceleration), for example, speeding up, slowing down, entering climbs or descents, and turning, Acts parallel to the center of thrust to overcome drag, F = MA, As a general rule, it is said to act parallel to the, Propeller & rotor driven aircraft are generally rated in horsepower, Turbine driven aircraft are generally rated in in pounds, Increasing engine power, increases thrust (now exceeding drag), thereby accelerating the aircraft, As long as the thrust continues to be greater than the drag, the aircraft continues to accelerate, When drag equals thrust, the aircraft flies at a constant airspeed, Engine power is reduced, lessoning thrust, thereby decelerating the aircraft, As long as the thrust is less than the drag, the aircraft continues to decelerate, To a point, as the aircraft slows down, the drag force will also decrease, The aircraft will continue to slow down until thrust again equals drag at which point the airspeed will stabilize, The pilot coordinates AOA and thrust in all speed regimes if the aircraft is to be held in level flight, Remember, (for a given airfoil shape) lift varies with the AOA and airspeed, Therefore, a large AOA at low airspeeds produces an equal amount of lift at high airspeeds with a low AOA. [, By looking at the cross section of a wing, one can see several obvious characteristics of design [, Notice that there is a difference in the curvatures (called cambers) of the upper and lower surfaces of the airfoil, The camber of the upper surface is more pronounced than that of the lower surface, which is usually somewhat flat, The two extremities of the airfoil profile also differ in appearance as the rounded end, which faces forward in flight, is called the leading edge; the other end, the trailing edge, is quite narrow and tapered, A straight line connecting the extremities of the leading and trailing edges denotes the Chord Line, The Chord line is a reference line often used in discussing the airfoil, The distance from this chord line to the upper and lower surfaces of the wing denotes the magnitude of the upper and lower camber at any point, Another reference line, drawn from the leading edge to the trailing edge, is the mean camber line, This mean line is equidistant at all points from the upper and lower surfaces, A certain amount of lift is generated by pressure conditions underneath the airfoil, Because of the manner in which air flows underneath the airfoil, a positive pressure results, particularly at higher angles of attack, There is another aspect to this airflow that must be considered, At a point close to the leading edge, the airflow is virtually stopped (stagnation point) and then gradually increases speed, At some point near the trailing edge, it again reaches a velocity equal to that on the upper surface, In conformance with Bernoulli's principle, where the airflow was slowed beneath the airfoil, a positive upward pressure was created (i.e., as the fluid speed decreases, the pressure must increase), Since the pressure differential between the upper and lower surface of the airfoil increases, total lift increases, If the airfoil profile were in the shape of a teardrop, the speed and the pressure changes of the air passing over the top and bottom would be the same on both sides, But if the teardrop shaped airfoil were cut in half lengthwise, a form resembling the basic airfoil (wing) section would result, If the airfoil were then inclined so the airflow strikes it at an angle, the air moving over the upper surface would be forced to move faster than the air moving along the bottom of the airfoil, This increased velocity reduces the pressure above the airfoil, Applying Bernoulli's Principle of Pressure, the increase in the speed of the air across the top of an airfoil produces a drop in pressure. They are free for airplane instructor applicants to use, I would ask though if you could just send me a thank you if it has helped you through your training. If the aircraft is operated in steady flight at L/DMAX, the total drag is at a minimum. Revision. Maneuverability: the capability of an aircraft to respond to the pilot’s control, especially with regard to flightpath and attitude. Therefore, to keep the aircraft straight and level (not accelerating upward) and in a state of equilibrium, as velocity is increased, lift must be kept constant. 092 IFR communications P. The applicable LOs for each licence or the instrument rating are marked with an Zx [. Three activities allow young flight engineers to understand the 4 principles of flight (weight, lift, thrust, and drag), to construct a glider, and to create a propeller. Explain what the flight controls are and characterize them by what they do. Force, weight and lift. This pull is called the weight force. Discuss the following systems in the aircraft to be flown.

Lesson Title: Principles of Flight Learning Outcome: Outline the principles of flight Linked Course Outcome: Analyze the elements of flight Learning Objectives: Students will learn the following knowledge, concepts, principles, and processes in this lesson: 1. Downwash points the relative wind downward, so the more downwash you have, the more your relative wind points downward. This induced downwash has nothing in common with the downwash that is necessary to produce lift. Rectangular course 9. Understand the flight controls (ailerons, elevator,rudder) and their aerodynamic principles. Understand the use of the flight controls and trim to control the aircraft. Young scholars explore the principles of flight. There are four main forces involved in flight. During this project, students will investigate the principles of flight. For Teachers 4th - 6th. The diagram is taken from the "Teacher'sGuide" to Flight: the Sky'sthe Limit, a 1975 Smithsonian Institution television film by Think of a hand being placed outside the car window at a high speed. The CFI, or Flight Instructor Notebook, is an instructor's guide to navigating the sea of resources in order to provide useful guidance for their students and themselves. In this inquiry-based lesson, students will will learn about energy transfer as well as motions and forces . The next few lessons should be roughly three hours each, including one hour actual flying for each session. Wind can cause a ball to roll, a book to open, water to move, etc. Principles of Flight Chapter 4. An airplane's aerodynamic balance and controllability are governed by changes in the CP, The production of lift is much more complex than a simple differential pressure between upper and lower airfoil surfaces. The lift and drag equations are as follows (L = Lift in pounds; D = Drag; CL = coefficient of lift; ρ = density (expressed in slugs per cubic feet); V = velocity (in feet per second); q = dynamic pressure per square foot (q = 1⁄2 ρv2); S = the area of the lifting body (in square feet); and CD = Ratio of drag pressure to dynamic pressure): Typically at low AOA, the coefficient of drag is low and small changes in AOA create only slight changes in the coefficient of drag. Similarly, as the aircraft reaches its never-exceed speed (VNE), the total drag increases rapidly due to the sharp increase of parasite drag, Reduction of induced drag during takeoffs and landings, Caused by a reduction of wingtip vortices, Occurs at about a wingspan above the ground, Down-wash can hit the ground and pushes the wing from below, forming what feels like a cushion, Causes floating if a fast approach is flown, Increases lift while decreasing drag (induced), thrust required, The opposite is true when leaving ground effect, Trim refers to employing adjustable aerodynamic devices on the aircraft to adjust forces so the pilot does not have to manually hold pressure on the controls, This is done either by trim tabs (small movable surfaces on the control surface) or by moving the neutral position of the entire control surface all together, Trim tabs are likely to be on the aileron, elevator and rudder, Trimming is accomplished by deflecting the tab in the direction opposite to that in which the primary control surface must be held, The force of the airflow striking the tab causes the main control surface to be deflected to a position that corrects the unbalanced condition of the aircraft, Because the trim tabs use airflow to function, trim is a function of speed. Faster air from above the airfoil moves downward. ATPL Principles of Flight 1-1 ©Atlantic Flight Training Chapter 1. engine cowlings, antennas, etc. Learn about Bernoulli’s principle, how the aerofoil works and the forces involved in flying. The lift/drag ratio (green) reaches its maximum at 6° AOA, meaning that at this angle, the most lift is obtained for the least amount of drag. Flight occurs from a combination of many physical principles, Daniel Bernoulli: fluid dynamics; increased speed creates decrease in pressure, Newton’s third law: every action has an equal and opposite reaction. [Figure 5-9] As the air (and vortices) roll off the back of your wing, they angle down, which is known as downwash. Interference drag: intersections of airstreams that creates eddy currents, turbulence, or restricts smooth airflow e.g. In this flight lesson, students construct a model plane and investigate the forces acting on the flier. The speed regimes of flight can be grouped in three categories: When the airspeed is low, the AOA must be relatively high if the balance between lift and weight is to be maintained [Figure 5-3], If thrust decreases and airspeed decreases, lift will become less than weight and the aircraft will start to descend, To maintain level flight, the pilot can increase the AOA an amount that generates a lift force again equal to the weight of the aircraft, While the aircraft will be flying more slowly, it will still maintain level flight, Straight-and-level flight in the slow-speed regime provides some interesting conditions relative to the equilibrium of forces, With the aircraft in a nose-high attitude, there is a vertical component of thrust that helps support it, For one thing, wing loading tends to be less than would be expected, In level flight, when thrust is increased, the aircraft speeds up and the lift increases, The aircraft will start to climb unless the AOA is decreased just enough to maintain the relationship between lift and weight, The timing of this decrease in AOA needs to be coordinated with the increase in thrust and airspeed. We don’t have wings and a power source strong enough to keep the wings moving through the air to sustain the lift necessary for flight. Lift (5 min) 3. Equipment: Understand the flight controls (ailerons, elevator,rudder) and their aerodynamic principles. Engineers also use their knowledge of these principles for other projects relating to fluid flow. Flight Instructor Lesson Plans. Fluids generally do not These are not constant values. Many thousands of airfoils have been tested in wind tunnels and in actual flight, but no one airfoil has been found that satisfies every flight requirement. In real life, of course, no one can just fly into the air. Aviation Information comes from a variety of sources which requires a lifetime of dedication to perfect. We will learn more about how Bernoulli's principle is related to flight in Lesson 2 of the Airplanes unit. www.drjayeshpatidar.blogspot.in 1/1/2014 80 81. In both examples, the only difference is the relationship of the airfoil with the oncoming airstream (angle). Pilot's can control lift principally with two factors: Any time the control yoke or stick is moved fore or aft, the AOA is changed, As the AOA increases, lift increases (all other factors being equal), When the aircraft reaches the maximum AOA, lift begins to diminish rapidly, This is the stalling AOA, known as CL-MAX critical AOA, Figure 5-5, shows how the CL increases until the critical AOA is reached, then decreases rapidly with any further increase in the AOA, For instance, in straight-and-level flight, cruising along at a constant altitude, altitude is maintained by adjusting lift to match the aircraft's velocity or cruise airspeed, while maintaining a state of equilibrium in which lift equals weight, In an approach to landing, when the pilot wishes to land as slowly as practical, it is necessary to increase AOA near maximum to maintain lift equal to the weight of the aircraft, Taking the equation further, one can see an aircraft could not continue to travel in level flight at a constant altitude and maintain the same AOA if the velocity is increased. Planes and birds have to be able to provide enough lift force to oppose the weight force. Remember what is needed to maintain lift and positive aircraft control and never disrupt these forces when you want to maintain flight. The lesson in progress 4.1 Teacher talk and student talk 4.2 Optimizing classroom interaction 5. This is induced drag, Parasite drag is comprised of all the forces that work to slow an aircraft's movement, As the term parasite implies, it is the drag that is not associated with the production of lift, Parasite drag therefore includes the displacement of the air by the aircraft, turbulence generated in the airstream, or a hindrance of air moving over the surface of the aircraft and airfoil, There are three types of parasite drag: form drag, interference drag, and skin friction, Form drag is the portion of parasite drag generated by the aircraft and components (antennas, wheels, etc.) ), In un-accelerated, level flight, the four forces are in equilibrium, Equilibrium is defined as lift equaling down-force (weight+tail down force), and thrust equaling drag, but by changing these forces we can affect climbs, descents, and other maneuvers. Lesson Plans can also be used as a companion book for flight instructors who are following the principles of scenario-based training taught in Arlynn McMahon’s first book, Train Like You Fly: A Flight Instructor’s Guide to Scenario-Based Training. It can be purchased a la carte. 2. 1. What is happening when I move this control—what is it doing? Forward slip to landing 19. Figure 5-10 shows the difference in downwash at Figure 5-9. 15 - Individual Lesson Plans Covering: Multi-Engine Pilot & Multi-Engine Instructor (MEI). Fundamentals of flight 8. Grade Level: 5-6 Subject Area: Math Time Required: Preparation: 1 hour; Activity: 2-3 hours; National Standards Correlation: Math (grade 3-5) Measurement Standard: Apply appropriate techniques, … Any change in speed results in the need to re-trim the aircraft, An aircraft properly trimmed in pitch seeks to return to the original speed before the change due to its, Trimming is a constant task as soon as you change any power setting, airspeed, altitude, or configuration, Proper trimming decreases pilot workload allowing for attention to be diverted elsewhere, especially important for instrument flying, In the pattern, if you have trimmed appropriately, you shouldn't have to use back stick at all, which should also prevent you from exceeding approach speed/on-speed, The principles of flight are those basic characteristics which act upon an aircraft, Although simplified as thrust, lift, weight, and drag, we know that there are more upward forces than just lift, and there are more downward forces than just weight, Although the pilot can only have limited control of some of these factors, principally, lift is affected by: Wing design, angle of attack, velocity, weight and loading, air temperature, and humidity, Both Bernoulli's Principle and Newton's Laws are in operation whenever lift is generated by an airfoil, You can see the four forces of flight are inter-related, In order to achieve flight, we must overcome drag, and resist gravity, In order to maintain a constant airspeed, thrust and drag must remain equal, just as lift and weight must be equal to maintain a constant altitude, Although lift is generally controlled through AoA and velocity, other factors are slightly under pilot control such as air density (as a pilot could change altitude), A balanced aircraft is a happy aircraft (fuel burn, efficiency, etc. At high AOA, small changes in the AOA cause significant changes in drag. FORCES ACTING ON THE AIRPLANE IN FLIGHT When in flight, there are certain forces acting on the airplane. While in steady-state flight, the attitude, direction, and speed of the airplane will remain constant until one or more of the basic forces changes in magnitude. Lesson 2-2a Principles of Flight - Lesson 2-2a Principles of Flight | PowerPoint PPT presentation | free to view . A third basic principle of flight is thrust, which in the case of an airplane is supplied by engine power. This is a website dedicated to CFI lesson plans.It’s great for both flight students and Certified Flight Instructors. The lift would increase and the aircraft would climb as a result of the increased lift force or speed up. Following these lessons, students learn how airplanes are controlled and use paper airplanes to demonstrate these principles. Give students an enjoyable introduction to the world of flight with some fun activities, interesting facts and cool demonstrations. Thus, modern airplanes have airfoils that strike a medium between extremes in design. Advancements in engineering have made it possible for today's high-speed jets to take advantage of the concave airfoil's high lift characteristics. Whenever an airfoil is producing lift, the pressure on the lower surface of it is greater than that on the upper surface (Bernoulli's Principle).
