How may a pilot indicate that no coded departure procedure is desired?

When a pilot indicates that no coded departure procedure is desired by including a statement in the remarks section of the flight plan, it effectively communicates their preference to air traffic control. Specifically, stating "no SID" (Standard Instrument Departure) ensures that the flight plan is processed without automatically assigning a standard departure route that could otherwise be expected for that airport.

This method is clear and unambiguous for both the pilot and air traffic control, allowing for flexibility in how the aircraft will depart, particularly when weather or other conditions make a standard departure procedure unsuitable. By incorporating such information in flight plans, pilots can tailor their departure strategy to align better with their flight intentions or operational needs while still adhering to safety and procedural protocols.

The other options may imply different forms of departure or route selections but do not directly convey the specific intent to bypass a standard departure method as effectively as stating it in the remarks section.
