sdlc 5 Posted October 28, 2014 Share Posted October 28, 2014 Hello, Just a "fine tuning" regarding calculated speeds :green dot, F, S and vref example at 64T Speed from mcdu A319 gd202, S187, F146, VRef 133 speed from QRH GD 218, S194,F148, VRef 130 Speed from mcdu A318 -Same as A319 speed from QRH GD 218, S192,F148 Vref 131 The variation with altitude is ok for green dot. Attached QRH extract for A318-319 I know it's a small issue.... Stephane Link to comment Share on other sites More sharing options...

Deputy Sheriffs The Dude 6537 Posted October 29, 2014 Deputy Sheriffs Share Posted October 29, 2014 We are looking into it. In the RW there is always a small differences between the speeds as the FAC, FMGC and QRH are calculating the speeds with different parameters. But I have also noticed that the green dot speeds in the sim are a bit more off then I normally see in RL. Can not promise you anything but we are checking it.

sdlc 5 Posted October 30, 2014 Author Share Posted October 30, 2014 Hi Frank, Yes. F, S, GD, are recalculated by the FAC. these speeds depend of VS 1G. For exemple, V4 (S speed) is 1.18 of VS 1G 0/0 the FAC uses a numbers of parameters to calculate the speeds ( voted AOA, VC, Thrust, CG, vertical acceleration, altitude, slats flaps ect...). It explains the small differences between qrh, and the speeds in the PFD. Stephane Link to comment Share on other sites More sharing options...
