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

The symbol T within a black triangle in the minimums section of an Instrument Approach Procedure (IAP) indicates that takeoff minimums are not standard. This is important information for pilots, as it signifies that the regular takeoff minimums established by the Federal Aviation Administration (FAA) do not apply at that airport or runway. Instead, pilots must adhere to the specific takeoff minimums that are published in the approach documentation.

Understanding this symbol is crucial for good aviation safety practices, as it alerts pilots that they need to consult additional guidance to determine the appropriate visibility and cloud clearance requirements before taking off. This ensures that pilots are aware of the specific conditions at that location, which may differ from standard procedures, thus enhancing situational awareness and operational safety.
