Question
How much part does the forecast (as opposed to actual) weather obtained before departure play in the decision to fly? On a long haul I can understand that the forecast can change. But in a short haul case like this it's probably fairly accurate. I also accept that it could well have said that the RVR was improving (or expected to improve) which would (in my view) have justified the departure. But if the forecast had been for weather that the crew were not equipped to handle is it legal and/or sensible to depart?
