guys,

am a newbie to complex engine management, but appreciate the extra speed i can squeeze out with it. i was wondering if, by changing the settings (propeller pitch, fuel richness, supercharger - though that last one I guess not) there is a change to prolong engine life (and make it back to base) in instances where you have been hit and you can hear the engine not working as it should?

Altitude is the best ting to have if your engine is on the blink. Even if your engine stops completely you might make it back to the right side of the line if you have sufficient altitude beforehand.

If your engine does die completely, remember to feather prop, pr change from auto-prop-pitch to manual-prop-pitch, and then set prop pitch to 0%.

Two of the best fights I ever had online were both in He-111s against a Hurris (I like to think they were Mk IIc's). Both times I RTB'd purely due to being at 5-6km alt before being trashed.

I think you would be surprised how far 1km (3000ft) would last you in a good glide.<div class="ev_tpc_signature">

Hi llama_thumper.

I'd say so. Generally speaking, by lowering rpm and boost a damaged engine may last longer before it quits than if the rpm and boost are kept at 'normal', high settings. All things being equal.

If damage is taken at high speed, say in a diving attack on a bomber, zooming for height before running away at reduced power is probably a good thing to do.<div class="ev_tpc_signature">

My preferred method is to crank everything to maximum power/boost and try to squeeze every last bit of power out of the engine to try and gain some altitude before it quits completely then use a shallow glide, sometimes using combat flaps. I generally figure you might as well make the most of the engine while it's still making useful power. Generally it's an oil leak that kills the engine and that oil will leak out at more or less the same rate regardless of how much you nurse it, and once it's gone your engine is going to overheat and sieze no matter how much babying you do. So I say just firewall that mofo, grab altitude while you can and hope it holds out long enough.

Also put it down as soon as possible, better to make a good landing on a road 1km from base than to run out of energy and crash 100m from the runway.

Assuming the sim is modeling things correctly, never use flaps when trying to glide. Anything that adds drag will reduce your glide range.

If I am in a two engine ac, I will immediately shut down the engine that is hit and save it for landing. As for a single engine ac, I have saved some engines that sounded like they would quit inside of a minute by immediately throttling back and adjusting the prop pitch down to reduce engine rpms even further. I have coaxed some heavily damaged engines home covering quite a distance using this method.<div class="ev_tpc_signature">

A damaged engine from gunfire or AA is precarious and unpredictable and something you can't really control. The advice given (i.e. gain as much altitude and head for friendly lines at reduced rpm etc,..) is sound.

On the other hand I find most people simply run their engines beyond the breaking point in their enthusiasm to get to the engagement area. My advice , in that regard, is to conserve and preserve your engine so it's there for you when you need it.

1. Use 90% (or less) prop-pitch instead of 100% as much as possible.

2. Cruise at &lt;80% throttle with rads open to ingress to the target area as much as possible (this will preserve your engine and make it easier for friendlies to join up without burning their engines trying to catch you)

Sure you've coaxed the engine home, but what happened to the plane, M8?! http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif<div class="ev_tpc_signature">

HEHE I believe you have witnessed me landing some wrecks more than a few times m8. And then again, you have seen me crash and burn a few after coaxing one home. And it was probably you that put the holes in my ac to start with. Lol<div class="ev_tpc_signature">

Well I had this problem last night in a co-op , I was escortin some he-111's on a torpedo run in a bf-109 and took a hit from the ships guns in the engine and started smokin and thought I might be able to make it to friendly lines before it pooped out so I began climbing with full power and it seemed like I would make it, closer closer and even closer I got then I ran out of gas and drowned.<div class="ev_tpc_signature">
