Flaps Up and Flaps not up

[Danial9874]

Flap up switch control rate of stab trim.
When flaps are up low speed trim engage
When flaps are not up high speed trim engage

What is the different between "Flaps up" and "flaps not up" ?
Flaps up = all flap retracted ?
Flaps not up = flap in extend position ?

Thanks

"Flaps not up" is what it says - any position other than fully retracted. It's a phrase that Boeing use (maybe others too) to describe the condition for many system characteristics, such as stab trim rate, that are controlled by flap selection. Can also be rendered as "Flaps out of up" - exactly the same thing.
