Stab Trim :
I don't understand though why they made themselves so visible to pax, and apparently not to pilots.
FAF interceptions are normally done by 2 a/c , one doing the intercept the other behind that will become active in case of non compliance . The pax maybe saw this one , the first one is close to the cockpit and is normally not visible from the back .
I do not think people flying to the sun today realize the State of alert our arm forces are in France regarding terrorism. Have a walk in any French city or airport today , the guys you see in fatigues are real , with real bullets . same in Spain by the way. If you overfly , better reply , " say again frequency " if you are not sure , or go back to previous in the frequency you tune in is silent ...
