It is common sense to telephone ahead. Firstly there may be a Notam you have missed (see above posting.) Secondly you get an update on the weather. In the U.K. as we all know a matter of a few miles or unusual local conditions can cause huge variations. Recently we were going to go to Garston Farm. Brize and Lyneham were both giving CAVOK but a check with the field's owner produced the response that they were 300 metres in fog caused by the fields elevation. There may also be a special briefing that you need. Finally knowing the runway in use gives you a chance to plan your approach by looking up the Plate.
