Historically, flying a helicopter has always been a challenge. From its beginnings some 70 years ago, flying a helicopter required a high degree of skill and constant attention. Even in the best of weather, in broad daylight, lacking either or both could be catastrophic. For all practical purposes, night flight and instrument flight were impossibilities. Not any longer. Since that time, vast improvements in basic helicopter design and avionics have occurred, making even single-pilot instrument flight rules (SPIFR) a reality while realizing major benefits, including greatly increased

The first are the elevators, which are devices on the tail of a plane that control pitch (the swaying of an aircraft around a horizontal axis perpendicular to the direction of motion). The rudder is also located on the tail of a plane. When the rudder is tilted to starboard (right), the aircraft yaws twists on a vertical axis in that direction. When the rudder is tilted to port (left), the craft yaws in the opposite direction. Finally, ailerons on the rear edge of each wing roll the plane from side to side.
Autopilots can control any or all of these surfaces. A single-axis autopilot manages just one set of controls, usually the ailerons. This simple type of autopilot is known as a "wing leveler" because, by controlling roll, it keeps the aircraft wings on an even keel. A two-axis autopilot manages elevators and ailerons. Finally, a three-axis autopilot manages all three basic control systems: ailerons, elevators and

4. Flight controls
Flight control is one of the lower-layer system and is similar to manned aviation: plane flight dynamics, control and automation, helicopter flight dynamics and controls and multirotor flight dynamics were researched long before the rise of UAVs.
Automatic flight involves multiple levels of priority. UAVs can be programmed to perform aggressive maneuvers or landing/perching on inclined surfaces, and then to climb toward better communication spots. Some UAVs can control flight with varying flight modelisation, such as VTOL designs(Fig 5.).5
UAVs can also implement perching on a flat vertical surface. Fig 5. Hybrid-Electric VTOL Aircraft.
5. Conclusion Interestingly, NASA also says that such a hybrid-electric design is “scale free” — meaning the same principles could be used to revolutionize everything from helicopters, to military UAVs, to massive jetliners. Much like hybrid-electric cars, the concept is set to revolutionize an entire fleet of aircraft designs that could be far more efficient than they currently are. One party who is sure to be interested in the possibilities is the US military, with its ever growing fleet of
Handling and operating an airplane comes with great risk, but these risks that are present are handled with very different attitudes and dealt with in different ways depending on the environment the pilots are in.
When World War I and World War II broke out, communication played a vital role in the sequence and timing of everything that occurred on the battlefield. If communication problems arose, the results could be fatal. Front line units needed to know where their neighboring troops were and commanders could only control the troops if they had a reliable source of communication. Due to modern forms of communication being unreliable, the men who served during these wars used a method that dates back to ancient times. They deployed wartime messengers also known as “carrier pigeons”. Today, communications are more reliable and unmanned aerial vehicles (UAV) provide us with aerial surveillance.1
They found that birds tilted their wings for balance and control, and tried to simulate this, developing a concept called “wing warping.” When they added a moveable rudder, the Wright brothers found they had the formula-on December 17, 1903, they succeeded in flying the first controlled flight of a power-driven airplane. Wilbur flew their plane for 59 seconds, at 852 feet, a crazy

Paper Airplanes, flight at its simplest for humans. As kids, we learned how to build paper airplanes and send them soaring into the sky. We didn't stop to think about why the airplanes where able to fly after the initial thrust we gave them or how they were able to glide for so long afterwards. Ignorance was bliss then, but now we strive to understand how things work. Looking back to the childhood past time of flying paper airplanes, I will try to explain some of the parts that make paper airplanes fly.
A. According to an article I read by Paul Scharre entitled “Do Drones Have A Future?”, the technology in these planes is becoming so advanced, that one day we may be able to have one pilot controlling multiple aircraft at once.
The FAA works on the gradual incorporation of rules and considerations in order to guarantee security and privacy. The U.S. Congress expects that in 2015 commercial drones will be ready to fly under regulated circumstances, but experts said that it would be until 2020 that unmanned aerial system are fully integrated. Nevertheless, laws will be published step by step according to their complexity and grade of autonomy. First small drones will be allowed to fly than larger ones, first drones operated by a ground-based pilot than automate long distance flights, and areas wi...
Flight is one of the most important achievements of mankind. We owe this achievement to the invention of the airfoil and understanding the physics that allow it to lift enormous weights into the sky.
...e in any one of these forces leads to a change in the others” (139). A pilot can use many different controls and means of propulsion to change and manipulate the balance of these forces. By doing this the pilot is able to change their speed and change their direction. The Physics of Flight are truly unbelievable occurrences that create amazing effects. Without the concept of flight we would live in a totally different world.
The history of flying dates back as early as the fifteenth century. A Renaissance man named Leonardo da Vinci introduced a flying machine known as the ornithopter. Da Vinci proposed the idea of a machine that had bird like flying capabilities. Today no ornithopters exist due to the restrictions of humans, and that the ornithopters just aren’t practical. During the eighteenth century a philosopher named Sir George Cayley had practical ideas of modern aircraft. Cayley never really designed any workable aircraft, but had many incredible ideas such as lift, thrust, and rigid wings to provide for lift. In the late nineteenth century the progress of aircraft picks up. Several designers such as Henson and Langley, both paved the way for the early 1900’s aircraft design. Two of the most important people in history of flight were the Wright Brothers. The Wright Brothers were given the nickname the “fathers of the heavier than air flying machine” for their numerous flights at their estate in Kitty Hawk, North Carolina. Orville and Wilbur Wright created a motor-powered biplane in which they established incredible feats of the time. The Wright Brothers perfected their design of the heavier than air flying ma...
Hybrid cars use both gas and electric. The gasoline engine is the primary source of power, while the electric motor is used at low speeds. Emissions levels are reduced because the gasoline engine shuts off at low speeds. An additional benefit of the parallel configuration is that no outside source of electric power is required because the engine itself generates the required electricity. A Hybrid Electric Vehicle known as HEV have several advantages over traditional internal combustion engine (ICE) vehicles: Regenerative braking capability, which helps minimize the energy lost when driving. Engine is sized to average load, not peak load, which reduces the weight of the engine. Fuel efficiency is greatly increased, while emissions are greatly decreased. HEVs can be operated using alternative fuels; therefore they need not be depended on fossil fuels (http://www.ott.doe.gov/hev/what.html#hev). Another great thing about these machines is the mpg; on the average, a hybrid car gets anywhere from 55-70mpg on the hwy. This is what makes the car all worth having. Now all this sounds good, but there are some issues that must be addressed.
The approach to artificial intelligence should be proceeded with caution. Throughout recent years and even decades before, it has been a technological dream to produce artificial intelligence. From movies, pop culture, and recent technological advancements, there is an obsession with robotics and their ability to perform actions that require human intelligence. Artificial intelligence has become a real and approachable realization today, but should be approached with care and diligence. Humans can create advanced artificial intelligence but should not because of the harm they may cause, the monumental advancement needed in the technology, and that its harm outweighs its benefits.
Drones or Unmanned Aerial Vehicles (UAVS) are controlled via two ways which are by pilots from ground or by a self directed pre-programmed mission. Cole and Wright (2010) identify that having various types, drones basically meant to serves the following two purposes:
...intainer. Our work has a major effect in the efficiency of the helicopter. Pilots, troops, and flight crews’ lives are in our hands. Causing harm to anyone by not doing my job correctly is not something that I would want to live with on my back. This is why we need to ensure we are complying with book standards to provide best quality of work in the safest way possible.
