A320 pilots: is the groundspeed mini invisible
Hello!
can anyone provide som clarity weather it is the case that on some tails the gs mini function is not displayed to the crew on the PFD by the VAPP being adjusted visually? Best regards |
Nope, not happening. GS mini modifies the speed target.
What you might be seeing is some secondary bugged feature of the A/THR. One of them is AFTER using speed-brakes with flaps out, it refuses to come down to the managed target for quite some time and floats 7-13 kt higher. |
Does anyone have the formula for ground speed mini by any chance?

Or am I thinking of Vls? |
Vapp+GS mini = 150
Vreal = 165 Speed-brake back in, as the thrust comes up, approach salvaged. A/THR reacts and flies 163 ish for 'like ages' (20-30 sec). Vls around 135, coming down from the speed-brake value within about 3 sec of the lever movement. I think there was a note of explanation somewhere once, but surely my memory banks get depowered too. |
