how do you land an la7. are there any films available.
-
:huh
uhmm just like any other fighter... slow down, flaps out, gentle & shallow approach.
The La-7 isn't particularly hard to land at all.
La-7 landing (http://www.mediafire.com/?sharekey=4b12b5cc24a8b0abc74f70ddb56f9ac856485f8f05165657)

Its one of the most forgiving to land. Like the IL-2 the Ruskies made em tough. Ive landed shotup LAs like bricks and still they held together. The real trick is in slowing them down because they glide like anything. You have to reduce RPMs and use reverse rudder to rock them about and slow them down for landing.
-
Reducing RPMs means reducing drag when gliding in. But as you want to slow down, you don't want reduced drag. So just lower manifold pressure (= throttle down), but don't reduce RPM's at the same time.
-
side slipping (skidding) the IL2 is sufficient enough to burn excess energy so you can land. As Lusche pointed out, adjusting RPM to help slow you down is not the way to do it.

Remember, land your plane as if it were an aerodynamic brick, gentle enough that it doesn't break, but going down enough so you don't miss.

don't listen to these guys.. they hate la7's... they're pulling ur chain. notice none of them said anything about putting the landing gear down?
besides everyone knows an la7 flys itself... lands itself too!

If you notice, I am a member of S.A.P.P and we are widely known for not using such silly things like landing gears or landing with the plane intact. Our motto is "The less parts you land with, the better the landing."

Search SAPP Landing techniques. While SAPP drivers fly 38s, the method will work with an LA7 as well.

Hey Dan, this link isn't working for me - or at least I don't have access to view it. :D

My mstake
Finished the night with some formation landing practice with Mensa. Thought I'd share some of my technique with the SAPP crowd in the hopes of helping others become better at putting their 38s down with style.
Note the smooth approach, flaps and gear out, curving in on final. Mensa looks a bit off in the background....but then again....it's Mensa.
(http://i152.photobucket.com/albums/s199/guppy35/Final.jpg)
Understand I'm trying to talk Mensa through this, and Soulyss is in the tower offering advice as well, but he's young and wants to go his own way....literally. Note I'm down nicely, center of the runway. Not sure what Mensa is doing.
(http://i152.photobucket.com/albums/s199/guppy35/Crossover.jpg)
Now that I'm down and centered, it's time for me to finish up. Note the smooth extention of the right wing, into the runway at about 45 degrees. This sets up the rest of the landing roll. Mensa is apparently trying to correct, but I'm afraid it's too late.
(http://i152.photobucket.com/albums/s199/guppy35/WingDig.jpg)
Continuing on, I lit a fire in hopes of giving Mensa something to guide in on. My landing roll continues.
(http://i152.photobucket.com/albums/s199/guppy35/Nosedown.jpg)
-
Now this is where I added a bit of style to the roll. Note I've gotten airborne again as I 'tuck' the nose under. This shows the sign of a real veteran on the landing roll. Again, I'm not sure what Mensa is doing, but I'm hoping he'll get better at this.
(http://i152.photobucket.com/albums/s199/guppy35/Jump.jpg)
Pay close attention to this part of the landing roll. Synchronized rudder removal is a sure sign of a veteran 38 pilot. It allows for a smoother surface to the 38 as the pilot completes his landing. As you can see by his 38 in the background, Mensa will need continued work on this.
(http://i152.photobucket.com/albums/s199/guppy35/Rudders.jpg)
Finally down and safe, center of the runway. The key is knowing when to kick the rudder and dig in the wingtip. You too, in time can land a 38 as well as this. But don't dispair. It's taken me years of practice to reach this level of ability:aok

I reduce RPMs and land successfully all the time. Slowing down is slowing down. No matter how you do it. All reducing manifold does is reduce RPMs, which slows you down. Whats the difference how you do it?

The difference is, that by further reducing rpm you simply reduce drag. It's doesen't prevent a succesful landing but it doesn't help either. It's just not helping you slowing down but on the contrary: it reduces drag and thus makes slowing down more difficult.
That's also the reason why to reduce rpm while gliding home with a non running engine. Minomum RPM = minimum drag from prop = longer gliding time (and distance)
-
:rofl CorkyJr. :lol
-
Lusche nailed it as ussual. Full RPM with idle throttle that prop actually acts as a big brake. Cut the rpm's and your removing a lot of airborne drag.
Line up far enough out to manage your speed. If your in a hurry, either lots of cross control (falling leaf from 8k is fun)
Or buzz the runway, at the far end of the runway kill your throttle, take the nose straight up. As its going up dump gear, flaps, horse the nose back around hard, line it up on the runway and pancake it in. Its quick, hard to shoot at if your being chased, and effective.
-
Dan, I laughed just as hard as when the first time you posted that Gem. :devil
-
Never realized that Mensa's lazy eye would make it difficult for him to land, my heart goes out to him.

I see what your saying now. At first I thought you were saying lowering RPM increases drag, which is what your trying to do anyways. I still find myself slowing down faster after I reduce RPMs because the engine is still running and its turning the prop. I would think the prop turning slower would increase drag by reducing thrust to weight. I often find myself trying to land an LA-7 when heavily outnumbered and have to slow it by reducing RPMs and spinning around my ack. One good thing about the plane is once youv slowed it it doesn't need much runway to stop. Not quite like a Spit but still not bad.
Anyhoo interesting about the engine out thing. Next time I'm trying to glide to base in a wirbeled IL-2, without power, I'll try reducing RPM too. Thanks for the tip.
-
Rich, when you reduce prop rpm you change the pitch of the prop,so instead of having the flat part of the blade facing forward,ie more drag,you angle the blade so the edge is facing forward. this make more work for the engine and thus reduces the rpm of prop.
So to land you want low MP{manifold pressure} and high rpm{most drag}
try this sometime,climb to say 10k go full rpm and MP then dive,note speed at say 2k
now do same only reduce just rpm and note speed... the difference is caused by drag.
hope this helps.

Czech pilots reported that the La5 (and probably therefore also the La7 which had 80 mm longer gear) exhibited a nasty bounce when landing. When trying to correct the bounce pilots tended to wreck the prop and so were taught to ignore it (ie let the ac bounce). These same ex RAF Czech pilots likened it to the bounce incurred on a Spitfire when landing.
In AH it is actually easier to land Lavochkins flaps up! with no damage generally incurred in doing so.

Gawd Corkyjr, I laughed so hard I cried :rofl :rofl :rofl :rofl Man I am just happy you are there for Mensa. :D
-
How can one of the funniest threads I have seen in years get to the 2nd page.
-
As for the La7. I have never dumped flaps in it. I've only used the "chop throttle" method. At the right speeds you can turn with almost anything in the game and better than the majority.

Another thing to try is get some alt, kill the engine and hit Alt x. After your glide rate is established reduce your RPms. You will see the nose come up higher on the horizon. This shows that you have reduced the drag induced by the prop and lengthening your glide.
