This Flight Planner Pad is ideal for domestic and international preflight and in-flight progress tracking. On the front side of each sheet is a place provided for preflight information such as planned course, altitude, predicted winds, en route checkpoints, compass headings, estimated times, fuel, navaid frequencies, and terminal information, field elevation, runway information, and communication frequencies. The backside of each sheet includes a preflight checklist, weight and balance computation table, PIREP guidance, and the flight plan format used by the International Civil Aviation Organization (ICAO). On October 1, 2015, the FAA will implement flight plan filing for civil aircraft exclusively under the format used by the ICAO. Flight plans contain specific information relating to the proposed flight of an aircraft and controllers use them to provide air traffic services.
