On the Embraer 145, when you push the 'config' button, she says:
"Take off- OK" or,
"Take off- Flaps" or whatever you forgot.
All configs should be like this. On my current type, we press it every sector, and if configured correctly- silence- like on the Spanair.
So how do we know if the config sys has failed?
Simple- we don't.
