Hi Pharcarnell.
The bar in that office is NOT connected to the outside atmosphere. That is why I thought the way they measure the pressure was dodgy. The QFE reading is also wrong as they use the pressure inside the office on the first floor WITHOUT any correction to runway threshold level. I guess that since no one has pranged a plane on landing, that the QNH value is reasonably correct. However, the method of measuring pressure in Darwin is definitely dodgy. Perhaps it is only a matter luck no one has crashed (yet)? Makes me wonder if they measure the pressure the same way in other met offices?
