For long time I have considered myself a proponent of moving TL (as most pilots are) even though the only A/T aircraft I have flown was the Bus.
However, I had a couple of jumpseat visits in the 737/767/787 FFS and witnessed quite a lot of trouble the moving TL's (sorry, throttles
) could give - eg. when the pilot forgot to disconnect the A/T during low speed RTO, or understanding mode reversions, fighting with A/T during flight, disconnecting servos the etc.
Having seen this (plus reading some accident/incident reports where A/T was a contributor), I have started to lean towards the Airbus system being actually simpler and more intuitive.
The only problem of the non-moving TL's is less intuitive intervention when the system is not doing what pilots want. I believe, however, that this could be addressed by training and some changes in procedures. We should be taught/trained/encouraged to grab the TL's (like Boeing guys do) instead of pushing buttons to get the engines do what we want...
