The Pe2 could fly on one engine?

Some say no but this article in a forum seems to say yes.

Umm..not quite sure what your point is with is. It's readily apparent that it could.

[Finkeren]

I’m wondering why some people would think that it couldn’t? It’s got a fairly low wingloading, pretty good power/weight ratio, high top speed and a twin tail that reduces the problem of asymetrical forces acting on the rudder when one engine is out.

 

The Pe-2 is an aircraft I’d absolutely assume could fly on one engine.

When I first read the title my brain was thinking Po-2.

 

A Po-2 can fly on one engine? You don't say...

To be fair, it can just about fly on one engine... ...barely.

I do break out into a bit of a cold sweat if I lose a PE - 2 engine at low level. I can maintain alt just about with one engine but that's about it.

BF110 G2 on the other hand has got me out of so many sticky situations with only one engine

It is not possible to feather the Pe2 prop is it? That seems like a major advantage the 110 has with flying on one engine.

No, you cannot feather the props on a Pe-2. Col. Ninny has a list of aircraft with props that you can feather at 8:45 of his video on complex engine management.

[senseispcc]

It is possible but difficult, like in reality; a great simulation, no?! 

[Finkeren]

I would go out on a limb and say, that the Pe-2 ought to be one of the easier twin engined aircraft to fly on one engine.

I think it's more that it can't quite reach the ground.

[HandyNasty]

afaik it depends on weather outside. If it mid july and like 30 degrees Celsius, you slowly but steadily lost altitude while flying on one engine. In winter (minus 20 maybe) you can fly on 1 engine. Am not sure though.

No my friend in real life you either can fly on one engine or you can't. The pressure/density altitude (give current load) only dictates what altitude you can hang on abovet  minimum control airspeed.

 

P.S. By the way here is Pe-2 POH in Russian where there is a short paragraph about flying on one engine https://yadi.sk/d/B-UBJ-2VoNdPr

I find it quite hard to fly on one engine and often find it is a slow sink to the ground.

I think what HandyNasty is talking about is, at lower temperatures, the remaining engine will have quite some more power, which makes it, of course, easier to handle it.

E2 as well, even on low altitude.

Pe2 flies into the ground nicely on 1 engine.  Best thing you can hope for is to be across friendly lines when you ditch.

 

110 and Ju88, no problem.  A pity as loosing an engine for the Pe is just a matter of how long you can keep it airborne as opposed to adjusting your plane and although, slower, making it back to base in the German twins.  So has been my experience, not sure how the A20 handles single engine flying as I haven't taken her out much.  More of a low level and dive bomber kind of guy myself especially online where AA tends to have great accuracy making mid level bombing a mugs game.

[JimTM]

I've managed to RTB on a single engine in the Pe-2 a few times and slowly drifted down to earth on other occasions. It's much more of a challenge if your critical engine goes out (the right engine in the Pe-2 and the left one in the A-20). See the following for more details:

Pe-2 POH states that upon engine failure pilot must immediately  compensate with opposite (to the failed engine)  rudder. Then establish bank 10-25 degrees toward the working engine and speed 280 km/h.  In modern times we refer to this procedure as "slip the ball, raise the dead"

 

Basically if you don't compensate for increase drag and slip you pretty much ended to sinking to the ground as described. Flying as usual but on one engine won't cut it. I would imagine if Pe-2 found in single engine operation at high altitude it would be forced to trade some altitude until off it can settle (considering lack of thrust) But it definitely should take one home .

 

Although it not mentioned in POH, a common sense suggests it would be much easier to fly on one engine by ejecting extra weight such bombs, rocket, tanks and etc

Density altitude does effect engine performance, but mostly in regards of take off and landing performance. You rarely find +30C  at altitude unless there is temperature inversion. Standard atmospheric lapse rate is 2C each 1000 ft - meaning each 1000 ft of altitude gain temperature drops 2 degrees C.  

 

I had a privilege to fly piston single/multi engine (none turbocharged) and somewhat under-powered  aircraft in weather condition +40C and more. I don't remember a single day where I was unable to climb to 10000 ft. However, I do remember trouble gaining altitude right after take off - but it was mostly due to my ignorance/stupidity at the time   

[Guest deleted@134347]

if you don't have too many holes in the wings it can fly pretty far on a single engine. Landing is tricky, can't drop airspeed below 150 unless you're couple of feet of the ground as it'll bank and you won't recover.

[-TBC-AeroAce]

I also find that the rudder even when trimmed does not have very good authority causing slip. I have only tried this when damaged so could be ok if the engine was just shut down.

By the way does anyone know maximum landing weight for Pe-2? By default before each mission in SP my tanks filled up way more than needed

I don't recollect seeing a 'maximum landing weight' specified in any of the WW2 aircraft pilots notes/manuals I've seen. If you were carrying bombs and had to return early, you would quite likely be instructed to dump them, but beyond that it was probably assumed that an aircraft could safely land at any weight it could take off on.

I did not see this number (maximum landing weight) for any plane in the game or am I mistaken?! 

Sorry for planes landing on carriers yes but land bases no.
