Yolk: yellow center of an egg.

Yoke: a control-wheel for an aircraft.

I've flown both. The pro-Boeing crowd often cites the ability to exceed hard-limits in emergency circumstances, such as an evasive pull-up for terrain or other aircraft. I've read, but can not confirm, that Airbus did a test for just that in the sim, by comparing the scenario in both a Boeing and Bus.

According to the story, that while the Boeing guys sometimes exceeded g/bank limits, it took them longer to achieve them. The Bus subjects could yank the stick to the limit, and achieved maximum g/bank earlier.

Result? The Bus survived more often.

I went through 777 training in 2002 but did not fly the aircraft due to being bumped-downward to the A-320. If I recall correctly, the FBW of the 777 is not significantly different from the A-320 in regards to g and bank limits. I'm certain it can't be rolled past a specific bank, but I'm less certain about g-protection.

Personally, I like the Bus, and have no problem with its control-laws.
