1. A method for controlling an operational condition of a turbine blade, the method comprising:
determining a minimum creep life location (MCLL) for a turbine blade design, the MCLL being a location at which minimum creep life occurs on the turbine blade design that fails fastest due to creep;
monitoring a temperature of the MCLL on a turbine blade having the turbine blade design in an aircraft engine using at least one sensor; and
when the temperature of the MCLL exceeds a predetermined temperature threshold, adjusting a temperature of air flowing about the turbine blade as the aircraft engine is operating.
