The aircraft profiles take TAS. However this is a function of temperature and altitude. Should the profile not work off IAS instead?

so it does!

Does the IAS get automatically adjusted for TAS then in the PLOG

next question. If I’m planning in advance how do I set the temperature as well as wind/v for the PLOG to work properly.

I don’t know whether/how it takes temp into account when no forecast met data is available.
