Stormer
Did the 727 last year and must admit i dont think it helped me.
According to my BA debrief the flying was fine for which i did a lot of raw data flying on line. It was two other areas critical to BA that i made errors on, simple things but important to them.
The 727 sim is brilliant but it was done as single crew and the emphasis was on the flying and not the two crew aspect.
If you do it which i would still recommend for some try and do it with another BA hopeful and concentrate on the two crew thing with an eye on the flying.
Good luck to one and all
