Non Safety issues
320 Fleet is as safe as all others or even better.
Consider a 320 lands ten times a day it is a week landings on A340.
So probability of exceeding the taxi speed or using reversers at less than 70 kts or flaring a bit high is more than A340.
Consider also that a lot of 320 flights are training you should expect these issues to come out.
But the 320 operation is as safe as all the others as it is one department.
320 330 MFF??? can the 330 guys handle the A320 operation??could be that is the issue??
MFF works both ways 320 -330 -320!!!!
