After you have completed your runup, take a moment to review your departure. Review the heading you will fly on departure and initial altitude to which you will climb. Review your initial clearance, which consists of your first fix and initial routing. Take a moment to mentally orient yourself to the departure runway, considering the direction of your first turn, terrain and obstructions in the area, and any adverse weather conditions. Review your plan for returning to your departure airport or other nearby airport in the event of an emergency.
An example departure review might sound like this: "Okay, we’ll be departing off runway one, initial heading is runway heading, initial altitude is 3000 feet. Our first fix will be Napoleon, and we will get there via radar vectors. There is no terrain, any obstructions, or adverse weather in the airport vicinity of which we need to be aware."
