26
What flight controls are electric?
Slats and horizontal stab
27
What are the Higher Level Functions provided by the FCM?
``` Elevator control laws Auto-thrust compensation AOA limiting Rudder airspeed gain and stoke limit YD and TC via AFCS Rudder flight authority Roll spoiler scheduling with speed-breaks Configuration change compensation ```
