I have entered only one power setting (Max Cruise) with several levels.
The airspeed type I chose is True (TAS).
Of course the airspeed depends on the level.
I then planned a flight with  a cruise at a high level, and a step descent due to airspace.
On the plog each level leg is shown with the Seal Level TAS, and the time for each leg is calculated with that TAS.
Climbing and descending legs are shown with a climb speed or a descend speed, but level legs are shown with the SL TAS.
Have I forgotten a parameter somewhere? Or is it a bug?

Do you mean entries in the aircraft performance profile? If so, had you set the equivalent flight level for your actual flight?


I had entered FL50, FL100 etc. in the aircraft performance profile
and FLxx for the actual flight, but the plog took into account only the lowest FL performance.
After having replaced FL by the equivalent altitude (FL50 with 5000ft etc.) in the performance profile, the plog became correct.
