What must a pilot possess to use an instrument departure procedure?

To use an instrument departure procedure, a pilot must possess a textual or graphic description of the procedure. This documentation is essential because it provides the pilot with critical information on how to safely and effectively navigate the initial phase of the flight after takeoff. The procedure includes altitude restrictions, routing, and any other specifics necessary to ensure compliance with air traffic control and safe operation within the airspace.

Having this description—either in a textual format or as a graphic depiction—ensures that the pilot is aware of the required procedures and can follow them, minimizing the risk of error during the departure phase. The other options do not meet the operational requirements: a verbal agreement from ATC, for instance, may not encompass all the necessary details, while relying solely on graphical representation may omit important text-based instructions. Lastly, not having any documentation contravenes the regulatory standards set forth for instrument flying, which emphasize the need for clear, accessible procedures.
