What does the symbol T within a black triangle in the minimums section indicate?

The symbol T within a black triangle in the minimums section specifically indicates that the takeoff minimums for that airport are not standard and/or that there may be published departure procedures that need to be followed. This is crucial information for pilots as it signifies the need to adhere to specific minimum requirements that differ from the standard takeoff minimums, ensuring that safety protocols associated with the specific airport conditions are met. Compliance with these unique requirements is essential for safe operation, particularly in environments where standard visibility or conditions may not be sufficient for a safe departure.
