Very true Maverick except that if you ran out of fuel in  one tank then there would be a chance that the engine would not start at all due to vapor lock,I forgot the exact name for when this happens to Fuel Injected systems,but it's pretty similar,the fuel line gets clogged by  gas vapor or air and one of 2 things might happen the air passes through the fuel lines to the combustion chamber and the fuel resumes  flowing once it's cleared, or the engine just doesn't restart due to the vapor or air creating a void in the fuel lines that does not let any fuel through.

"If engine reliability is going to be taken into account, the the N1k2's engine needs to randomly die. And the me262 engines need to catch on fire randomly when being started. "

Why?   It's not the same issue.   Serice reliability for planes like the N1K2 is NOT the same thing as damage caused to an engine by a pilot needlessly abusing it.    

It's much more like airframe failures in AH....poor construction isn't modeled in AH (N1K2's landing gear doesn't randomly break), but if you over-abuse your plane (pull too many G's or such) you CAN make it fail.  

Engines should be the same way.....abuse it and risk losing it.

Glasses, that is why fuel boost pumps were installed. Even if you had a vapor lock there was a considerable amount of flow in the line and the fuel would get there. Besides there was more than one fuel line to the selector. The reason selectors were used is to allow the engine to be fed from any tank and in some cases from all of them (internal tanks). Don't forget you will have an instant fuel line break as soon as you drop your drop tanks.

No, I'm not talking about modeling random failures.

I'm talking about player induced failures.  You start your engine, you get into a fight.  Yer about to get yer bellybutton handed to you so you start poppin the button you've programed to start the engine.  Every time you kill the engine in your scissors fight you run the risk of damaging the engine.  The more times you kill it the more likely it will not restart and you end up dead anyway.

Big difference between random and player induced here.

Now about runnin fuel tanks out... I'd have to go try it again, but it seems like every time the engine on my pony has died because I burned out the aux tank before the external tanks, the engine restarted as soon as I switched to a tank with fuel in it.

Pretty much the way it is in RL too. Engine's already turning, has spark from the mags, add fuel and there's noise.

Not really.
Shutting down and restarting an engine is little different from it's working in the first place.  If it's going to randomly die when you restart it, why shouldn't the rest be taken into account?

The whole engine issue is stupid anyways.  It's a question of engine reliability, which is something that won't be modeled.

Lets also have the 262 flame out if you advance the throttle too quickly.

Do WWII planes have sparkplugs or do they work like diesel engines and rely on compresion and heat?

(I don't know $@#! about engines)

They had sparkplugs for the most part. The Germans did have some diesels but they were not good performers ike the gassers were.

It's a "gamey" tactic no doubt. To end it they could simply make it 30 seconds to REstart an engine. That way if you accidently hit e while tooling along or wanted to shut down to conserve fuel it wouldn't matter. Doesn't matter to me either way. I griped about it, even to Skuzzy. He said it was "fairplay". So I have simply started using it and I must say, it works well. :D

Maverick,

Wow!  I had no idea.  A couple minutes of web searching and I found this.


BNM,

A few people have tested this now and found that there is no performance difference between toggling the engine and simply cutting throttle all the way back.  So while the ability to have a 100% reliable instant restart might be an open question the tactic itself is no better or worse than chopping throttle.  I doubt that anyone is going to argue that chopping throttle is "gamey."
