| Wind speed and direction, for example.

| speed and direction?

All of them. Most if not all the panel mounts will display constant
real time wind direction and speed if you wire in the inputs it needs.
Heading, altitude, etc. Some handhelds can do this but usually you
would just go to the menu and do a one time check of the winds, density
altitude and TAS.
