What should a pilot do if they do not wish to use an instrument departure procedure?

When a pilot does not wish to use an instrument departure procedure (IDP), entering "No DP" in the IFR flight plan remarks is the appropriate action to take. This notation clearly informs air traffic control (ATC) and other relevant parties that the pilot intends to depart without utilizing the standard instrument procedure.

Notifying ATC through the flight plan helps ensure that they are aware of the pilot's intentions, which can help in managing the departure sequence and ensuring safety. In situations where an IDP is available, it's crucial for a pilot to communicate their preference for an alternate way of departing to avoid confusion and maintain the efficiency of air traffic operations.

The other options do not provide a direct and proper method for indicating a pilot's intention concerning an IDP. Simply filing a complaint or requesting a waiver may not effectively communicate the pilot's plans regarding departure procedures. Calling flight services would not necessarily facilitate the required notification in a way that is recognized or processed by ATC, and doing so wouldn’t directly impact the meant outcome of the flight planning.
