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 indicates that takeoff minimums are not standard and/or that there are specific published departure procedures that must be followed. This notation is essential for pilots as it alerts them to the fact that the usual minimums for visibility and runway length that they might typically rely on do not apply in this situation. It also emphasizes the need for awareness of any additional requirements or procedural specifics necessary for a safe departure. This ensures that pilots are prepared for any unique challenges or restrictions that may be in place, enhancing safety during takeoff operations.
