Standard Noise. The procedure that has been followed for the past few months at this airport(since the new tower was opened) was that we gave our flight plan details, ATC put the details into the computer and gave us a squawk after a few min after the computer assigned us one. However today they said because of the work to rule we would have to file a "proper" plan. Oh well it looks like we need to get used to this because this dispute is going to get much worse I think
