Hold on for a minute.......
It is not a turbine only term! Look in any number of piston engine
manuals and especially with fuel injection for "HOT START PROCEDURES".
It happens generally with high ambient temperatures when the fuel air
mixture ratio is not correct or normal. Each engine will require
different procedures according to the manufacturer.

OK, I didn't think of that. I have very little piston time- in aircraft
anyway...

This is the same term for for apples and oranges though. In a turbine hot
start the risk is damaging the engine. In a piston hot start the risks is
not starting, right? Like flooding a car engine on a hot summer day, or did
I get the wrong idea?

Anyway, you learn something new every day, and I'm glad my explanation made
sense to Peter Maus.

As I said, your explanation was essentially good across the board for
turbines and I couldn't have said it better . I've seen some awesome
examples of hot starts with turbine and one that resulted in a rapid
meltdown of a PT6. I'm glad it wasn't me with my finger on the start!!
Most generally the flawed hot start with piston can result in a dead
battery, or burning up a starter. I've seen at least one fire started
with a starter that got overheated and ignited wires and insulation.
In any case, its wise to know the correct procedures for each and
important to follow them!
