11 Hoffmann 2 H 36 DIMONA Limitations 2.9 Cont. To reduce the risk of encountering control flutter at Vne the following table should be used to determine Vne at various altitudes. ALTITUDE (m) 0 – 2000 (ft) 0 - 6500 3000 10000 4000 13000 5000 16500 6000 20000 Vne (km/h) 275 (kts) 149 259 140 246 133 233 126 221 119 NOTE Maneuvering speed (Va ) is the maximum speed at which application of full available aerodynamic control will not overstress the airplane. Increasing altitude increases True Air Speed (TAS). Indicated Airspeed Errors The following table illustrates airspeed errors (IAS) due to positioning of the pitot pressure and pitot static sources. Pitot and Static Pressure source: Leading edge Horizontal Stabilizer. 2—5

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
