747-400 Elevator Feel
For all the 400 experts out there....
The 400 elevator Feel Computer/ Feel Unit are designed to provide artificial feel forces to the control column to simulate changes in both airspeed and horizontal stabiliser position.
I can see how the amount of effort required to move the stick would increase as the aircraft flew faster, but what effect does stabiliser position have on the stick... Does it make it harder/easier to move... or somehow changes the neutral/centre position of the stick?(Looking at the design of the computer, I can't see how it can do the latter. Also, the tests listed in the Boeing Maintenance Manual do not offer any insight into Elev Feel ops).
Thanks for any input.
Rgds.
