Whenever an aircraft changes its flight attitude or position in flight, it rotates about one or more of the three axes. Is this statement true or false?

Whenever an aircraft changes its flight attitude or position in flight, it rotates about one or more of the three axes. Is this statement true or false?

• A. True
• B. False
• C. Sometimes
• D. Not Always

Answer: (A)

The key idea is that an aircraft’s orientation in space is described by rotations about its three axes: the long axis runs nose to tail, the lateral axis runs wingtip to wingtip, and the vertical axis runs top to bottom. When the airplane changes its attitude, it does so by rotating around one or more of these axes—roll changes about the long axis, pitch about the lateral axis, and yaw about the vertical axis. If the aircraft also changes position in flight, that change in trajectory typically comes from reorienting the aircraft to direct its velocity differently, which again involves bending about those axes. So, any change in attitude or movement to a new location in flight is accomplished through rotations about the three axes, making this statement true.
