Beispiel:

The Boeing 787 uses:

Fly-by-wire (FBW) control laws
A highly integrated Flight Control System (FCS)
Flap and Slat Electronic Units (FSEUs)
Flight Management System (FMS) protections
These systems actively prevent unsafe or uncertified configurations.

They manage:

Slat/flap sequencing and timing
Speed protection (e.g., retract inhibition above VFE)
Configuration alerts (e.g., FLAP LOAD RELIEF)
Operational logic (e.g., takeoff config check)
As a result, only discrete, certified flap settings can be selected via the flap lever. The system won’t respond to intermediate or invalid positions.
