Thanks for this.

I have some questions;

Would you lower flaps before lowering gear on a landing approach?

I always figured the flaps were not to be deployed fully at speeds above 250 km/h, where the gear can be lowered at speeds of up to 350 km/h.

I always lower the gear on the base leg, and on final I lower the flaps to full landing config.

Why would one make a full stop on the runway only to be told by the tower to clear the runway asap. Wouldn't slowing down to taxi speed and then taxi away be a faster method to clear the runway? How is this done in RL? And how was that done during that battle?

 

I printed the list and I will use it as reference the next time the server is online.

Thanks.

[=38=Tatarenko]

I lower both flaps and gear at about 250. I haven't noticed damage to either if they are lowered under 300 or so. Clearly that may change as the game develops but this works for now.

 

Re stopping before going over to taxi - I find that transitioning to taxiing while still moving can lead to ground loops. I like to taxi with a bit of brake on to help the rudder pedals and to move at a steady speed. It is the accelerating and decelerating where trouble can happen. But yes, if I'm nicely lined up I'll often just taxi straight off as well, but often too fast and I mess up that bend.

 

So this is a nice and safe method. I have brakes on a slider but not everyone done.

Oh, and the flaps and gear together cancel out the pitch tendencies of the other, so that works well too by lowering them at the same time.

[=38=Tatarenko]

(In general regarding this - I'm sure there are stacks of ways to do these things. This is what I do. Other ways are just as good.

I will amend this as the sim progresses.)

Great post. Would like to see a video with this list as the basis

 

That's a great idea. I have no talent in that direction but if anyone does, that would be marvellous and help the new chaps.

Good list. Presuming this is translated from the Russian Lagg-3 Manual? I have it but it wasn't completely translated for me. I've done a video on the Lagg startup as a rough example of what to expect from future videos below. Once access re-opens you can expect to see an official one released from me shortly after (will include the later parts of the flight). My classes are over for this semester, so I've kicked back into video making gear for my time off

Bando: What you describe seems typical for WWII fighters - lower the gear at around 300 km/h (which would be on downwind if you fly a circuit pattern) to bleed off speed, then lower the flaps as needed (depending on whether you are high or low), maybe in increments, on base and final.

[=38=Tatarenko]

No, it's just what works for me.

 

I just thought I'd write it down because a mate wants to have a play and things that I do automatically I might not remember when it's not my hands on the stick.

 

Also there's stuff I don't remember like closing the Messer cockpit or centering hardware trim (almost caused a few crashes on t/o with that!)

[Bando]

LOL

 

Closing the cockpit should indeed be there in the list.

I had some cold flights. In fact, a lot of them.

One criticism: one should always start the engine with the prop in fully fine (max RPM) to take load off the starter.

Very nice reference, thank you!

As you have no control over the prop pitch at low throttle and the engine will be turning over less that 1600 RPM in any case (and therefore be automatically at coarse prop pitch) I'm not sure that makes sense. I would set low RPM to start the plane as well.

[Allons]

Love the list especially because half of the crowd will enter the fighting with nav lights on giving us the chance to set them to off manually one by one

[Matt]

"Pitch full forward" might cause some incidents during take-off.

 

I would replace "pitch" with "Propeller Pitch" or, more accurately, "RPM lever" (but that might again confuse people).

 

Why should you increase (from what?) the throttle to 30% after landing?

 

I would trim after or while lowering the undercarriage and flaps and not before (i know trim doesn't work yet, but still).

 

Personal preference from me is to center the rudder shortly before taking-off. That way your wing won't drop and you won't need ailerons to compensate.

 

Also the LaGG has a flap position indicator gauge, so i would use that to set the flaps during take-off (20° max) and not time it.

[=38=Tatarenko]

1) Pitch full forward - if this confuses you there's a bicycle down the hall.

 

2) Increase the throttle during the rollout once the rudder loses authority to give airflow over the rudder to prevent ground loops. If you start turning the rudder can immediately be used to counter it. The brakes aren't very effective at high ground speeds but should be on full with the tail back. You will still slow down but can control direction if necessary. The LaGG has no locking tailwheel. If you never ground loop, that's cool.

 

3) The wing doesn't drop because of the rudder but because the airscrew provides asymmetrical lift over the wings at low speed. So yes, you need ailerons.

 

4) Flaps - saves looking down. Both work, obv.

[Matt]

Easy. I thought this was meant to be helpful to other people.

 

3) The wing doesn't drop because of the rudder but because the airscrew provides asymmetrical lift over the wings at low speed. So yes, you need ailerons.

It doesn't drop just because of the rudder, but you need way less aileron input if you center the rudder first.

 

Anyway, just a suggestion.

[=38=Tatarenko]

Indeed. Whatever works.

[SYN_Speck]

1) Pitch full forward - if this confuses you there's a bicycle down the hall.

 

I have to agree with Matt. It may be obvious to you but I think a lot of people will be confused by this, thinking you men elevator control forward rather than prop pitch.

 

Otherwise, very helpful post, thanks.

[RAF74_Winger]

As you have no control over the prop pitch at low throttle and the engine will be turning over less that 1600 RPM in any case (and therefore be automatically at coarse prop pitch) I'm not sure that makes sense. I would set low RPM to start the plane as well.

 

There is sufficient oil pressure to adjust the pitch even at low throttle. The lack of control of pitch at lower manifold pressures just means that the prop has hit the fine stops and can't go any further to increase RPM. It will not be at coarse pitch.

As a Silver Surfer Pimpin' Platinum Member, I found this summary very helpful. I have a couple of questions since I still have not taken off on my lagg-3 on expert (or normal for that matter, but I dive in head first). I have yet to land properly in my BF though but that is another topic.

 

What happens is that I run out of run way and go into the fields and still don't have enough speed to generate any lift.

 

Here is what I do.

 

P to unpause.

 

hold F for 4 seconds for flaps.

 

E while throttle 20%.

 

Hold down minus, alt-minus, rcrtl-minus, rwindows-minus for all the Complex engine management stuff which I don't quite understand. Hopfully I am doing this part correct .

 

Hold / for brakes.

 

Increase throttle to 50%.

 

Release brakes start rolling, applying rudder to correct.

 

Once Sufficient speed throttle to full.

 

Pull back on the stick to keep the back wheel on the ground.

 

Run out of run way and end up in the fields, again.

 

Any pointers?

[Bando]

Did you set your rpm to fully forward (the little lever just below the throttle). If not you're not going to get airborne.  Hope this helps.

[kongxinga]

Success, thanks Bando and the guy who made Lagg-3 manual with pictures so I could figure out what thingy has to be forward or backwards. I even semi landed it (only lost 1 wing and one gear after messing up a bounce with excessive braking).

 

Start up procedures for people with el cheapo joysticks (aka all commands except flight surfaces and zoom and look on keyboard, defaults).

 

1. P to unpause.

 

2. Ralt-C to close cockpit (forgot this).

 

3. Do warm-up or do skip it like I did (not a good i dea).

 

4. Rshift+Equals and Ctrl Shift+Equals and RWindows+Equals and Ralt+Equals. Mixture should be lean, but I did not do 1005 lean. .This should open water and oil radiators, and increase pitch to fine.

 

5. Hold F for 5 seconds.

 

6. E and hold slash. Throttle 25%.

 

7. Throttle 50%, release slash, counter torque with rudder.

8. Full throttle.

 

9. Pull up.

 

10. G to take in gear.

 

11. Lshift-F to raise flaps.

 

12. Enjoy your wobbly lagg.

You'll get the hang of it. I find the 109 to be easier to fly. Lagg has a somewhat larger workload. 109 on the other hand has still some features disabled. Ah, we'll see in due time what the devs have planned. It'll be awesome, no doubt.
