well u'd normally get your wind direction and speed from your ATC :rolleyes:

The wing low method is usually good for high-wing airplanes :D. Seriously, it's much better to crab when you don't want your wingtip to catch the runway on landing. With the Bf it might be okay, large dihedral, wings not too long...

With regards to the crosswind component, some airplanes have limitations, some (high-wing Cessnas :)) have only the demonstrated crosswind value. It's like saying "this is what the test pilot was able to pull off, now let's see what you can do :)". Personally, I landed with about 16kt gusty crosswind in 172s and it's bordering unpleasant. 67kts? I'd consider staying at home :D.

+1 here.

Now, I have to say this having been a flight instructor in Canada. Most europeans won't use the slide technique (wing low) for landing as for north American, it's the first one that's being thaugt. In fact, the slide was apparently removed from the PP training syllabus in France. The low airspeed indicated is normal only as you flare. That is, the crab approach should not cause any different speed indication since the plane has nothing to do with it's trajectory over ground. When you flare and de-crab, you go sideways from what the air around the plane travels, exposing the pitot tube to an angle thus creating the difference in airspeed. That's just another (there are many more) reason why we have two pitot tubes in airliners nowadays.

That decrease in IAS also tells you that the downwind wing is also partly "shadowed" or airflow-obscured by the fuselage. That momentarily affect the aerodynamic wingload and most likely loose so lift. That why, without passengers, you can start decrabbing earlier and set your attitude 1/4 mile before touchdown if you want.

Now, with your 108 km/h wind setting, I would not even think of going up for a spin, let alone trying a wing low landing!!! I'm sure they were all inside, sipping tea with scones and crumpets...
;)

Hey, really good explanation! anyway this can be considered an instrument installation error, ins'nt it?

Will do more suitable tests... in that way :)

67 knot crosswind is no problem in a Cessna 172 or similar because it's above the stall speed. Therefore it's not a crosswind anymore because you effectively have a VTOL capability and so you can always takeoff & land directly into wind. :-P

However, you obviously would have to be very careful about wind gradients & gusts.

Best approach technique would probably be to come in at 80-90 knots with flaps retracted so that your approach angle relative to the ground was shallow enough that you could keep the touchdown point in view.

There therefore a very definite worst crosswind speed for any given aircraft type, such that the wind is strong enough to cause trouble, but weak enough to prevent you from taking off or landing across the runway etc.

The biggest challenge in really strong winds (i.e. those similar to the stall speed of the aeroplane) is moving the aeroplane around on the ground, because the weathercocking tendency and roll due to sideslip forces can be very large.

As a rule of thumb, if you can taxi the aeroplane then you can fly it.

Here's a landing in 45 knot winds. http://www.liveleak.com/view?i=a98_1303334732


There shouldn't be any error in the speedo while crabbed, as the crab itself only relates to relative ground movement, not the aircraft through the air so the speedo error is weird (probably another bug ...).

Also, did anyone else notice the 109's flaperons (drooping ailerons). They dropped 3 degrees (hardly noticeable) with flaps at takeoff position and 11 degrees for full flaps. This feature was discontinued beginning with the F. This wasn't included in IL-2 Mark 1.

Instrumentation error, yes. Is it like that in reality, yes. That is, on single pitot installation, which I believe all WWII era fighters were equipped with.

As for some people saying that the wing low technique is only for high wing aircraft, I must say it isn't true. I personnaly accomplished hundreds of real life landing with the wing low technique on CRJs, B767 and EMJs without even coming close to scrapping a wingtip. Well executed, there should be no reason why your upwind wheel wouldn't touch the pavement (grass) before the same side wingtip. Just for fun, in game of course, record a track of low speed flying above the runway with gear and flaps downs. Not trying to land, just bank until the wingtip strikes the ground, play the track at low speed and you'll notice that you need quite a bit of bank to strike the wingtip. As a matter of fact, the amount of bank would probably be higher than what the rudder would be able to compensate for going straight, which is what you attemp to accomplish in a crosswind landing.

Hope this helps. Cheers.

Could somebody please explain in simple what menu to look at. I cant find the weather options at all in the FMB. There is some menu that says Locales but it´s grayed out and cant be accessed. I would also like to try out the weather. I can use the local weather objects but don´t seem to know how to make the winds as the text is all messed up.

Seriously? Instrument error in straight ahead coordinated flight? So you can't expect a reasonably reliable reading on any given approach? How so?
I've experienced errors during extreme slips and skids but nothing significant (as illustrated in OP's movie) in a simple approach.

That's not what I wrote. Read again mate.

I said, when you de-crab and start side slipping for your flare, you start having IAS error. Straight and level flight should not be affected; apart of course by compressibility and position error.
