And that's my point. Even on the 320, quite a few think this thing will roll inverted and smash into the ground behind a 767 and want to fly high. If you want to fly a half dot high, that's your prerogative. A large category aircraft like the 320 family has enough mass, inertia, wingspan, and aileron authority that it will not violently roll over and cause you to lose control.

This was actually one of the factors cited in the AA 587 crash. The NTSB came down harshly on the AAMP training curriculum, in which one scenario in the sim flying behind a 747, and they would roll the MD80/A300 a full 90 degrees due to wake and then have the pilot recover. It was all BS, and grossly exaggerated the expectancy of a wake disturbance on a large, transport category aircraft. No doubt this was in the back of the mind of the AA 587 FO as he violently overcontrolled the aircraft. No large transport category aircraft has flipped over and crashed behind a 757/767 or other heavy aircraft while on approach from 500ft-3000+ft AGL.

The one exception was the Delta DC9-10 (almost RJ type) in the traffic pattern with a DC10 also doing touch n goes in Texas, and they caught the wake below a 100 feet, corrected in one direction, overcorrected in another direction, and with not enough altitude they rolled upside on the runway and crashed. But this was on short final, in a non-normal operation of a heavy doing touch n goes.

It's just an eye rolling moment when some think a large transport category aircraft like an Airbus will behave like a small business jet for wake and lose control and crash
