OK, so maybe some fly at night, and others really do fly in clouds (I bet it was purely by mistake though...). My point was really that the restriction seems like a rather unnecessary "we don't thrust you pilot-twats to do this right"-statement.
What about a B737? Does its wind shields stop a bird from entering the flight deck at an effective speed of 300kias? I dunno... Just wonder WHY the restriction is there on the Q4, and not other aircraft.
