A320 run-ups
Just been told by our company that we are to do a run-up prior to every takeoff in icing conditions (10c or less and visible moisture). So +10c and raining, we're doing a 30 sec run-up to 70% N1 in position using about 110kg of fuel.
We used to have 30 minutes of taxi time before this was required but now it's changed.
Any other airbus drivers doing this?
