Does the TPE331 in the Conquest have SRL computers, auto SPR or something similar that prevents an overtemp during start?
Yes it does and works really well as long as the computers/FCU have been correctly set up and operational and the P3 filters and other input devices, viz transducers and temp probes are calibrated corredctly. In other words properly maintained.
Good battery at a minimum or APU start if possible and all will be fine.
If the indicated EGT was in excess of, and I think I recall it correctly 200C then you would get a hotty unless you motored the engine down below this level before selecting start. This is where you can get into real trouble if your batteries aren't up to scratch.
Garrett stats say without a doubt the most significant "hot start" issue is;
Battery dies or dying or APU plug falling out during the 28% vibration/resonance transit and before the starter/gen swapover spoils your whole day if you aren't ready for a manual cut off.
Our ops manual called for Fuel cut offs cocked and identified during the start for immediate removal of fuel in the event of a trend towards "hot".
The stop buttons are only any good if they are powered. It's also not a bad idea to have a plastic bottle screw top on board whilst training to place over the "live" engine stop button.
The other "bad habit" for young players was leaving their finger on the start button during the start. This button is programmed after initial start selection for the introduction of extra fuel above the start profile to "goose it" if necessary/appropriate for faster acceleration of the engine within temp profiles if required. Leave finger on button big bunch of fuel
Beautiful engine and computers, sipped fuel as long as you understood exactly what was going on at all times, training, and I met few who rarely did beyond the "basic run down" they got on endorsement.
