One thing to watch in a turbine is the mass airflow. The re-start needs careful monitoring because the forward speed is stuffing a lot more air in than a static start on the ground. Get a bit carried away and you can get a BIG overtemp.

Did it once in an S61 which tried to overtemp and once in a 332 which was warm, but within limits. Seen it in a 355 and it was a non-event. On the S61 we gave up and continued on one, the 332 was following a precautionary shut down when base engineering advised (as did the book) having the engine going for the arrival. Always wondered that bit as the 332 was always so powerful.
