Hi,

I often change waypoint altitudes from "at or above" to "at" in order to ensure compliance with altitude constraints.

On top of this, I also dial in the platform altitude on the MCP. This is belt and braces, as well as correct procedure.

However, too often during the approach phase, the aircraft continues to descend beyond the altitude constraint as well as the altitude dialled into the MCP.

At this time, the LOC may be already active, but the G/S is not yet alive let alone one dot above.

The A310 really should not descend at this descend, and yet all too often, and easily reproducibly, it does.

Thoughts?

Thanks,

Fabio

If you can tell me those easily reproducibly steps, I'll take a look at it 🙂 So far, for me it never went below the constraint.

Will do.
