What should a pilot do if instructed to disregard SID restrictions?

When a pilot is instructed to disregard Standard Instrument Departure (SID) restrictions, the appropriate course of action is to climb unrestricted as necessary. This instruction typically indicates that the original SID restrictions are no longer applicable, and the pilot is allowed to operate without those limitations.

The SID restrictions are designed to ensure safe and efficient routing during departure, including altitude and speed requirements. If air traffic control (ATC) instructs a pilot to disregard them, it implies that the pilot should follow the new guidance provided by ATC, which may include climbing to a certain altitude without the constraints of the SID.

While the option to proceed as per the filed route may seem viable, it does not account for the specific instruction from ATC to disregard the SID, which typically overrides previous routing expectations. Contacting ATC for clarification would generally be unnecessary if a clear instruction has already been given; the pilot should instead act upon the directive received. Maintaining the published SID restrictions contradicts the explicit instruction to disregard them, making it an inappropriate option in this scenario.
