Narrative:

Conducting a visual approach to runway 23L sidestep runway 23R at mex. At about 3000 ft AGL aircraft encountered unexpected wake vortex. Aircraft rolled rapidly to right approximately 45-55 degrees. Recovery initiated in accordance with company training for advanced maneuvers. 2 mins later we were told of a heavy airbus landing on runway 23L. Had mexican ATC warned of the heavy, I could have flown above the GS. Callback conversation with reporter revealed the following: report was used for structured callback and following information was obtained. Reporter had just completed the new program initiated by his company for advanced maneuvers training. The experience with the airbus was almost identical to the simulator training he had completed. He said it was almost like a time warp where for a nanno second he felt he was back in the simulator. He feels that is why he handled the situation so well and with very little stress. He feels strongly that all air carrier's should institute such a program.
