<![CDATA[THR RED and CLB ACC altitude amendment don't change performance]]>Hi,

It seems that when I change the thrust reduction and climb acceleration altitude in the FMS, the aircraft sticks to 1500 ft AGL for both altitudes.

It is important that all mandatory fields in the FMS are completed prior to takeoff (square boxes on the INIT A/INIT B pages) in order for the FMS to have sufficient data to operate.

I am able to reproduce the problem on all flights I'm doing.

Attached a screenshot of a departure out of Amsterdam, with NAV, PROF and ATS already armed on the ground. I amended the THR RED altitude to 1000 ft and CLB ACC to 1500 ft, just for testing purposes.

In the screenshot I am well above these altitudes, and I've manually engaged climb mode, but climb mode is also still armed. The vertical mode is still in TO.

I will also open a ticket for this issue.
