Concorde climb without afterburner

When you do a full climb without the afterburners to 60000 ft the autopilot of the Concorde struggles extremely with the climb rate and the speed. There’s always the warning that the speed is to high. It seems like in Aerofly the Concorde has a better climb performance without the afterburners than with them.

btw. This wasn’t the case a half year ago until ipacs changed something with the Concorde.

You can try it by yourself. I always use the max climb function but in the end it automatically switches back to normal mode (which is realistic).The issue happens only with the max climb function actually
