Don’t Get Stuck—Avoiding Breakdowns and Delays
Running the battery down by leaving the battery or master switch on is, arguably, the most common reason for a departure delay. I use a “Parking” or “Shutdown Checklist” before deplaning to avoid this. Some pilots leave the rotating beacon on after shut down as a clue that the battery switch was left on. Full service FBOs will have external power available to get you going quickly if the battery is dead.
