    Maybe...?

    Well, fortunately for us, most non-Pakistani airlines do give a rat's ass. So we have managed guidance and a descent mode on the A320 that maintains a speed range around the best fuel-economy speed while taking into account altitude constrictions and brings you down to the glideslope where you can make a nice, passenger-friendly, life-sustaining transistion to final. Why not use this? Why not respect the value of human life over your own ego? Why be a cowboy when cowboys are a thing of the past?

      I'm afraid you're incorrect. For LVL CHG climb thrust will go to CLB, for LVL CHG descend thrust will go to idle. Provided A/T is on, of course.

        Not surprisingly...

        Thank you.
        And if you manually move the levers out of CLB or idle, will they automatically return to CLB and idle? (always with the AT on)

        I need to go back to my manuals of the Mad Dog add-on for Flight Simulator (half-joking)... I think it was different in the MD-80. If I remember correctly selecting IAS/MACH in the vertical mode would do nothing with the thrust. And even if you select a descent the plane would climb if you select more thrust that what is required to hold the altitude at the speed selected in the IAS/MACH vertical mode. I think that the AT mode went to CLMP (clamp, the AT will stop moving the levers), and from there you can manually set the levers where you want or you can select an EPR hold AT mode and select CR, CLB, MCT, or TOGA. If you select a speed hold mode in the AT it would disconnect the IAS/MACH vertical mode and change to a vertical speed mode with the current altitude target and current actual vertical speed.

        So, for example, if you are crusing at FL330 and want to climb to FL350 at the current Mach, you would select 35000 in the altitude window, select IAS/MACH (the IAS/MACH window, which is the same as the vertical speed window, will show the current Mach), and then select CLB thrust rating computer and EPR hold in the AT.

        If you want to descent from cruise, you would select say 10000 ft, IAS/MACH mode, manually idle the throttles, and select the desired IAS/Mach value. In the meantime you would select (but not activate) 250kts in the AT window so when the plane reaches 10000 ft it will level off and slow down to 250 kts and hold it.

        But it has been many years since I last used this add-on so my memory may be off.

          AFIAK, there are only two ways to get out of OP DES/idle thrust on the A320:

          - arrive at the selected altitude entered in the FCU (assuming it's not 0, as sometimes has been the case).
          - manually select another vertical mode.

          Is this correct?

            Or get rid of the automation altogether.

              Affirmative.
