Hi Ronnie
As A340Driver says - they are pretty cool once you get used to them - which takes about 30 seconds! For the avoidance of confusion however - The only time they "don't move" is when :
1. They are at idle - conventional
2. During take off when they are at TOGA or FLX/MCT - conventional.
3. When they are in the CLB detent with the Auto thrust active - non-conventional.
When the autothrust is not engaged, they are entirely conventional - the pilot moves them back and forth according to the thrust level he/she requires.
So as you see - the much trumpeted "non-moving" thrust levers are not in fact all that different to conventional aeroplanes.
Hope this helps
