No feul engines off i dive down for my field
at sealevel i make some turn too under 200 mph
i lower gear and extend a little flap and speed brakes a shake heavily with rudder touchdown at about under 150mph
Than i brake brake and brake damn the plane doesn't stop it overshoots the runway and i die.
I'm very tired off the long glide path u have and the bad breaking.
I have none off the problems when my engines are running, than i always can point my landing whereever i want.
I really think it has to be fixed.
I don't understand nobody feels the same or is it only with the P38?
Anyway there is a big difference between the powered and none powered landing
when this is the cause off the drag from proppelor than i want too be able too turn feathering off so to add extra drag.'
Another question what bearings is used coz the plane rolls forever . (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif)

Maybe lack of hydraulic pressure affects braking power?

I've noticed in the 109f4, that you roll much less if you are holding down the brake as you land.

150 is WAY too fast to be landing a WW2 fighter. Slow it down first and you will have no problem stopping.

what funked said.
i've come in almost on top of the field in a downward spiral, pulled realllll hard to slow her down and touched down with no probs. try around 90-120mph. use everything you can, flaps, brakes, speed brakes, engines off....etc etc.
-
seems nobody understands me.
Normal landings are no problem landings without engine power are a problem
my speed was below 150 could be 120 with 90 it falls dowmn like a brick.
and yes i hold down space bar to break
i also stick nose down maximum when on the ground to push the plane on the runway.
none off the manouvres got big effect.
only with engine power not without.

My personal feeling is that the P-38 glides a little too well in a clean configuration, especially when in ground effect. I have no data to back it up, just my real life flying experience. Go to full flaps, however and it decelerates very quickly to below flying speed.
To avoid running off of the runway, make sure you slow down on final with full flaps and gear. Touch down in a nose high attitude at 100 mph after the flare within the first third of the runway. Some airplanes will roll to a stop without any brakes before reaching the other end of the runway. If you feel you can't judge runway height when the nose obscures the runway before touchdown, try a shallow gliding turn to final to keep the runway in sight through the side windscreen.
If you touchdown at 150 its almost a given that the airplane will bounce back in the air making wheel brakes inneffective until you get them back on the ground below flying (and coincidently, bouncing) speed.

I know you guys are trying to help, but I think his point is getting lost. I think he's just trying to say that with the engines off, the P-38 does not glide or retain E like he thinks it should. He's saying it doesn't lose E fast enough in power-off flight.

I see one thing you are doing wrong. Don't stick the nose down on landing, pull it up. Apply brakes and gradually pull the nose up. Once you're below 100mph, pull all the way back and don't let off the brakes. It's the quickest way to land in any aircraft. If you're going too fast, and pull up, it'll lift off the ground, stall and dump a wing. I've done just that in a corsair many times, even have film of it. My Chog landings are infamous, as I always seem to bounce the aircraft a few times.
Landing Films (http://www.worldaccessnet.com/~delta6/htbin/landings.zip)
Corsair Landing (http://www.worldaccessnet.com/~delta6/htbin/film4.zip)
The landing films file is me doing landings in 4 aircraft. Note the funny way I managed to get a Chog down. The Corsair landing file is a simulated carrier landing. I land that way every time I fly, with a very steep approach and fast rotation. Aside from getting down fast, you've got squat for speed after rotating. Slam on the brakes and pull up hard to stop, after your speed drops below 100mph.

Thanks Raubvogel

Bug.. I too have a b#tch of a time landing engine out. If you are coming in that fast, I know perhaps you are in a hurry to get back up, but i'd suggest going around again, or at least instead of comin straight in for landing (N-S for example) overfly the runway and come back the other way, after bleeding some speed off.

I dunno. I have zero stick time in any real planes. And I have no data on real P-38 glide performance.
I do know that Bob Hoover used to do a routine in the P-38 where he did a loop off the deck with both props feathered. So the plane was obviously pretty darn slick as far as retaining energy.

I noticed the same thing the other night (last night with the Osty Heaven terrain). I landed a P-38 after having run out of fuel, and did a normal touchdown, perhaps a bit on the fast side, but I'm sure I'd have been able to stop normally. Now, however, it seemed like the brakes did nothing, and I rolled past the end of they runway and continued for a good kilometer before stopping. Seemed a little wierd to me, but if it _is_ a hydraulic thing it'd at least be logical (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif).

I noticed this as well in a P-51 tonight.
I made a very good dead stick landing, with full flaps deployed. I touched down at about 110-120mph almost at the extreme end of the runway. I applied brakes immediately and not really much happened.
I attempted to further slow down by using full up elevator. This seemed to have little effect.
Eventually, I came to a stop past the other end of the runway. The coast down distance / time seemed extreme and much different than with the engine at idle.

Now we get too the point.
ok maybe hydrolics out
but than there still should be a hand brake
-
No handbrakes on WW2 fighters (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
I wonder if it's hydrolic thing - not sure about P38 but in a Pony everything was hydrolical hence hanging gear doors when engine stopped - no pressure in the system to keep them up. When the engine started they would come up to open again to accept gear in flight (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif).
It's prolly a bug but if engine off kills your power assists off - it's pretty neat piece of modelling... Makes survivability of a wounded bird so much more shakey!

Mino 110-120 mph is too hot to land a P-51. Historical touchdown speed is about 90 mph.

In P-38, you have to lose some speed just before landing, because if you roll too fast, you won't stop until next county.
BUT, if you lose speed so that you touchdown at around 100mph, you brake alot quicker.
It seems too that if you glide just off the runway so that you lose 50mph more speed and then land, you get into stop alot sooner than if you land at 150mph instead of gliding off that 50mph..

CC and thanks Funked, but like I said I was dead stick. I still should have stayed on the runway as I landed on the extreme end of it. The brakes just seemed to have very little or no effect.
This non-braking so surprised me that I asked all my squad mates if there was something different with the brakes. The difference in breaking ability was very noticeable since I last flew, which was a little over a week before. This happened to be my first flight of the day and I had lost my radiator then the engine quit after attacking a BUFF.
With engine running, the plane slows very rapidly and brakes seem very effective. With engine off via damage and not windmilling, roll out takes easily 2-3 times the length.
Even at 50 mph tapping the brakes did not produce the normal stuttering effect. Just really kind of feels like the brakes were not working at all.
The P-51 brakes using the keyboard are normally very sensitive below 50 mph. If you are not careful you can go bellybutton over tea kettle before you know it.

Roger Mino I see your point.
Also that 90 mph figure I'm quoting is power-on, full flaps, gear down. With no power a higher figure is probably appropriate considering drag from flaps and gear.
IMHO the change in brake function with engine off is worthy of a bug report.

Once you touch down, if you raise your flaps all the way it will help a lot.
