Here is a problem that we can all work. Maybe this practical example will answer our questions. We seem to be able to quote, cut and paste things pretty well, but let's apply it. Let's keep it fun and contempt free.

Departure from Sioux Falls, SD (KFSD).

It's 0200, the tower is closed. It is dark. The FBO is out of coffee. Starbucks is closed.

Runway 15 is the only runway open. The winds are 150 at 25 anyway. The lineman put a gun to your head, you WILL use runway 15....get the point...?

The ceiling is 100 feet, the visibility is 1/4 mile. You want to fly IFR, it is IFR.

You are Part 91.

There is no published SID. There is the "Trouble "T" in the front fodder of the NACO approach plates.

To quote Keanu Reeves in "Speed..."

"What would you do....WHAT WOULD YOU DO?"
