What is required if an instrument departure procedure is accepted?

When an instrument departure procedure (IDP) is accepted, possessing a textual or graphic description of the procedure is essential. This requirement ensures that the pilot is fully aware of the specifics of the procedure, including waypoints, altitudes, and any special instructions that may affect the flight path during departure.

Understanding the details laid out in the textual or graphic description allows pilots to execute the departure safely and efficiently, as well as remain compliant with air traffic control (ATC) instructions and potential airspace restrictions. This knowledge is critical for effective navigation and communication with ATC throughout the flight.

Having a personal GPS device, filing an alternate flight plan, or communicating with ATC may be relevant for overall flight planning and safety, but they are not mandatory prerequisites for accepting an instrument departure procedure in the same way that understanding the specific procedure itself is.
