This answer to this question is incorrect on several levels.
- The question was about turbine engines, the answer was about jet engines.
- The answer is about starting the engine, but the question does not mention that.
- The answer is incorrect about the reason turbine engines take so long to spool up. A turbine engine with the same rotational inertia as a piston engine will definitely start slower. The answer is not consistent with that fact.
- If the question is, in fact, about starting, a turbine engine has to spin much faster than a piston engine in order to start. After ignition (at the higher speed), a turbine engine cannot accelerate to idle (an even higher speed) too fast or it overheats.
- An upvoted comment compares the starting speed of an A320 engine to a piston engine?
- The battery is not normally the limiting factor for a turbine engine start. The starter motor is turned off well before a turbine engine reaches idle speed.
I don't know what, if anything, should be done about it, but I do know that this kind of thing does not make the site look good.
