Hello, in the B744 PFD appears, during cruise, a yellow message, just under the vertical speed indicator that says: "NO TDZ". What does it mean? I gave a look at the manual but I didn't find it.Thanks a lot to everyoneBest RegardsLorenzo Chiovaro

Hi Lorenzo,It means no 'touch down zone' has been selected in the FMC It occurs roughly half way through the flight and is a gentle reminder that you need to set up at least a arrival runway. Once you have done that the message will clear.Hope that helps!Rob

Yes, it helped very much. Is was exacly what I was loking for. Thanks a lot for this explanation.Best RegardsLorenzo Chiovaro
