Adverse yaw!!! Roll causes Yaw and Yaw causes Roll...

Do you know what adverse yaw is and how to solve it? To understand what adverse yaw is, we need to first explain the axes of motion for an  airplane. An aircraft in flight can rotate around three different axes, as illustrated below. Aircraft control surfaces However, the effect of one control surface is not always limited to just pitch, roll, or yaw  alone. When the deflection of one control surface affects more than one of these  orientations, we say that the orientations are coupled. The most important of these  coupled interactions is adverse yaw. To better understand the concept, let's study a  picture of what happens when the pilot deflects the ailerons to roll the aircraft. As you can see, the aircraft rolls because one aileron is deflected downward while the other is deflected upward. Lift increases on the wing with the downward-deflected aileron because the deflection effectively increases the camber of that portion of the wing. Conversely, lift decreas...

Boeing aircraft parts are manufactured in the Nagpur-India MUST WATCH : VIDEO-BOEING-TAL MIHAN PROJECT NAGPUR... Maharashtra Chief Minister Devendra Fadnavis on Friday said Nagpur is on the global map because of aviation company Boeing and the Tata Group. It is a proud moment for all of us that some key parts for a Boeing aircraft are manufactured in the Nagpur,” Fadnavis said, adding with the help of Tata Group, MIHAN has put the country on the global aviation map. The chief minister dispatched the 5000th ‘beam’ from TAL Manufacturing Solutions to Boeing at a function at MIHAN Nagpur. TAL is a Tata Group entity. “City-based based TAL is manufacturing major parts for Boeing aircraft and Airbus also. It shows that Nagpur and Vidarbha region has talent along with the best human resources,” Fadnavis said. “When I was at Boeing’s headquarters in US, I was told that this part (beam) came from Nagpur. It was a proud moment for me. TAL would be the brand ambassador of the country in the aeros...
