A helicopter (also often used: chopper or heli) is a kind of flying machine or aircraft. A helicopter lifts up off of the ground and moves because of its rotors. A rotor is several small wings, called rotor blades, that spin together around a shaft. For that reason, helicopters are sometimes called rotary-wing aircraft. A helicopter flies differently from an airplane. An airplane must move.
The proposed revised definition of PC1 in ICAO:Performance Class 1 operations are those with performance such that, in the event of a critical power unit failure, performance is available to enable the helicopter to safely continue the flight, to an appropriate landing area, unless the failure occurs prior to reaching the take-off decision point (TDP) or after passing the landing decision.
Performance Class 2 helicopter. EurLex-2 (a) In the event of critical power-unit failure, at or after the take-off decision point (for performance Class 1) or the defined point after take-off (for performance Class 2 ), performance Classes 1 and 2 helicopters shall be capable of continuing safe flight, the remaining power-unit(s) being operated within the approved limitations.
Performance Class 1 helicopter. A helicopter with performance such that, in case of engine failure, it is able to land on the rejected take-off area or safely continue the flight to an appropriate landing area. EurLex-2 (For performance Class 1 helicopters only) The take-off decision point shall be the point in the take-off phase used in determining take-off performance and from which either a.

Helicopter Technique. The Helicopter Approach of Storytelling and Story Acting is based on the work of Vivian Gussin Paley, Patron to MakeBelieve Arts. MakeBelieve Arts has been pioneering this work in the UK since its conception in 2002. In its simplest form children tell their stories which are written down verbatim, word for word. The group then gathers around a taped out stage and the.Learn More
Though crude it proved the gunship’s worth and would lead to development of more advanced purpose built gunships such as the Bell AH-1 Cobra, the first attack helicopter (Tucker, 2010). So important and versatile was the AH-1 Cobra that the U.S. Marine Corps still utilizes the Cobra today. It has gone through several avionics upgrades to meet current military aviation demands (Update on.Learn More
With the largest cabin in its class, wide opening sliding door and roll-in stretcher capacity, the H160 is the next generation high intensive care helicopter ideal for long distances critical patient or incubator transport. High Resolution. Low Resolution. The H135 is known for its endurance, compact build, low sound levels, reliability, versatility and competitive cost. High Resolution. Low.Learn More
The term “helicopter parenting” refers to the involvement in a child’s life that is overbearing, overprotective, and controlling. Helicopter parents are most commonly exposed by high school or college-age students because they are old enough to realize that the parents are taking over tasks that the student is capable of completing alone (Journal of College Counseling.Learn More
Welcome to Helicopter Lessons in 10 Minutes or Less! My goal with this channel is to break down and teach helicopter aerodynamics topics, one-by-one, in a format that's easy to grasp.Learn More
The same can’t be said for helicopter pilots whose view is pretty good, to say the least. Whether it is flying above the New York skyline, over active volcanoes in Hawaii, or taking in the Grand Canyon in Arizona, helicopter pilots work on a daily basis in the most spectacular location on Earth.Learn More
Helicopter Performance Chapter 7. 7-2 Factors Affecting Performance A helicopter’s performance is dependent on the power output of the engine and the lift produced by the rotors, whether it is the main rotor(s) or tail rotor. Any factor that affects engine and rotor efficiency affects performance. The three major factors that affect performance are density altitude, weight, and wind. The.Learn More
Then on November 13, 1907, the French pioneer Paul Cornu lifted a twin- rotored helicopter into the air entirely without assistance from the ground for a few seconds. After that, several models were produced by many designs but there were no more great advances until another French pioneer, Etienne Oehmichen, became the first to fly a helicopter a kilometer in a closed circuit in 1924. It was.Learn More
Imagine you have been asked to design a helicopter to drop supplies to people in a remote disaster area. A controlled descent and soft landing is essential - too fast might damage the load and too slow might blow off course! Here is a template for one possible helicopter (Word, pdf). Once you have had a go, think about how the helicopter could be adapted. How would you decide on the best.Learn More
The structures of the helicopter are designed to give the helicopter its unique flight characteristics. A simplified explanation of how a helicopter flies is that the rotors are rotating airfoils that provide lift similar to the way wings provide lift on a fixed-wing aircraft. Air flows faster over the curved upper surface of the rotors, causing a negative pressure and thus, lifting the.Learn More
Helicopter Stories: Letting Imagination Fly What is Helicopter Stories?

The rotating wings of a helicopter are shaped just like the airfoils of an airplane wing, but generally the wings on a helicopter’s rotor are narrow and thin because they must spin so quickly. The helicopter’s rotating wing assembly is normally called the main rotor. If you give the main rotor wings a slight angle of attack on the shaft and spin the shaft, the wings start to develop lift.Learn More
