Nor is it present on the newer A320 with IAE engines, as flown by BA and BMI. It was found not to be necessary, following line experience with the original A320 CFM aircraft. I would be very surprised if it was fitted to the A318.
Looks a bit short to me, although it will make our A319s look less stumpy once we see it around the place. Glad I won't have to fly it - same wing as an A320 but 50 less seats - it will be a b@gger to slow down.
