Hi there,
I am on air, for a flight from Milan (LIMC) to Tromso (ENTC).
I have noticed that the “managed speed” is stuck at 252nots, while in the MCDU for the ongoin lag it should be 0.77 Mach …I am a bit confused …see the pictures below
Everything looks correct. Look below the speed tape. See the .766? That’s your current Mach number. Indicated airspeed appears low due to the lower air density at the altitude you are at. If you look on your navigation display at the top it shows your True Airspeed (TAS) as 451.
Perhaps I’m wrong here, but it actually looks like you are in “selected” speed mode, because the mode control panel is showing a mach number. If you are in managed speed mode, it should be blank/dashes with a dot showing (like the heading display to the right).
Try pushing in the speed knob to engage “managed” mode and see if your speed goes to your CRZ speed setting.
