What does a negative 'T' inside a triangle indicate on certain aviation charts?

Explanation:
A negative T inside a triangle marks nonstandard takeoff minimums. Seeing this tells you that the takeoff minimums for that departure aren’t the standard ones, so you must consult the chart notes or the takeoff minimums section for the exact numbers and any special conditions. Those nonstandard minimums could require higher visibility, a greater ceiling, or additional climb requirements, depending on the runway and procedure. This symbol is specifically about takeoff minimums, not weather minimums, altitude restrictions, or terrain warnings, which use different indicators on charts.
