Support overload. We are currently seeing 65% more demand for support then we normally see. We can only assume this is because more people are at home due to the corona crises. Our complete support staff is online and they are working flat out, but it will take some days before we can scale up resources. Please be patient.

On the PERF APPR, the FMS shows TRANS FL but displays an altitude, like the FMSs where it shows TRANS ALT.

 

From the FCOM, THALES2 FMS:

Hi @becas, I did further investigation. TRANS FL is correct for Thales, TRANS ALT is Honeywell.
But it should show a FL value.
Added it to the bug tracking system.

FCOM:
Displays the Transition Level, computed by the FMS based on the
Transition Altitude (extracted from the database) and the QNH value
entered in the [1L] field. It is rounded to the upper multiple of 5. By
default, it is displayed in small blue font.
The crew can modify it (it is then displayed in large blue font).

@becas you are correct. Just discovered:

A330 has TRANS ALT

A32S has TRANS FL

Both Thales FMS2 Release1A. Just one more small difference of the longrangeFMS vs shortrangeFMS.
