As an aircraft moves through the air, the air molecules near the aircraft are disturbed and move around the aircraft. | Fill in the length of each leg of the flight plan between your aircraft and the destination, working backward from the airport (including final), then press "Calculate". day_names[day_names.length] = "Tuesday"; // -->. Before takeoff and landing, the pilot obtains a local barometric reading from the airport and sets it in the small window using the knob.
