What phrase should pilots use in their flight plan to avoid a SID?

The phrase "No SID" is a direct and clear way for pilots to indicate that they do not wish to participate in a Standard Instrument Departure (SID) as part of their flight plan. Using this straightforward term communicates their intention clearly to air traffic control and is easily understood without ambiguity.

In aviation communication, brevity and clarity are crucial, and "No SID" effectively conveys the message without any extraneous wording that might confuse controllers. Other phrases such as "Exclude SID," "Bypass SID," or "No Standard Instrument Departure" might not be recognized as standard terminology, which could lead to misunderstandings or delays in processing the flight plan. Therefore, the use of "No SID" aligns with established communication practices in the aviation industry.
