Willadvise,
You make a good point - I can also own up to that.
Without sounding defensive, let me just say this :
I think it is just a thing pilots do to try and sound nice - like they are not insisting on it.
How would you suggest we emphasise the difference between something that we would "like" to have and something we "must" have eg aah - maybe a bad example, but say weather avoidance - definitely can't go through a thunderstorm, so that is not just a "nice" to have?
Thanx guys.
