Tornado F3 - asymmetric engine configuration ?

[ORAC]

From elsewhere - There are fences in both intakes But in different places. One intake is optimised for high AOA, and the other for low speed airflow. The idea is that it's less likely that gross mishandling will flame-out both engines at the same time.....

Cowl fence in the left hand intake, duct fences in the right. (P1420 below)
