Once it warms up, does your temperature/bias remain reasonably constant?

I'm asking because, with another project's autopilot, we found that we
needed a preflight procedure to solve this problem: let the board come
up to temperature for a few minutes then reboot it.

Are you aware of another project's autopilot with a temperature/bias
compensation that actually works?
