Great feedback guys - thank you. The idle temp limit is 515C and max continuous limit is 675C. The engine in question is actually a T73/JFTD12 as used in S64 cranes, an engine derived from the JT12 used in the sabreliners. I’m think the idea of increased engine load and subsequent T5 spike during a second engine start sequence would not be applicable in this scenario because it utilizes hydraulic starters driven from an accessory gearbox furnished from APP, but maybe it’s an old carryover from the Sabreliner limit. 🤔
