Punkalouver,
then I guess I better stop flying because there are a whole world of "what if's" that can happen. No Alternate is safe. It's up to you to decide whether or not the flight plan can be carried out under No Alt. There was a small period of time when our SOP's did not require the min fuel of 5000lbs and so theoretically Dispatch could min us to 3200lbs. I remember watching a Captain here get all tied up in a knot because the DXP had given him 5000lbs and No Alt. The DX'er said, "O.K., I'll give you an Alternate" and provided him one that only required 4800LBS. Hmmmm.....
As professional pilots, we have a responsibility towards Safety. That is first and foremost. We also have a responsibility towards the economic operation of our companies that cannot be ignored.
