OK the answer to this one is very simple, VNE stands for 'Velocity never exceed' the never is not optional. Pulling the airbrakes or pulling back hard on the stick may cause structural damage to the glider, however this structural damage is not likely to be catastrophic. Why not? Exceeding VNE may induce aerodynamic flutter, this can and almost certainly will cause catastrophic failure of the airframe. Put simply try and avoid both but if the choice is exceed the placarded G loading or VNE the G loading is the only choice. The potential for catastophic failure is much much greater if VNE is exceeded, Why? exceeding VNE is therefore not an option. Isn't there a built in safety margin for both G's and VNE? I have no doubt there will now be lots of postings from people who say they have exceeded VNE and got away with it. Even idiots can be lucky sometimes. |
