crosswindlandings in cliffs...

[David198502]

hey guys, i just created a mission, where you will have to land with crosswinds.
the wind comes from a 90°direction to the runway...
but somehow i dont manage to land my plane safe...a few seconds after touchdown, my plane will tilt or collapse...and this only with a wind strength of 15 of the possible 50...

Are you using opposite aileron?

hope its usefull for something :grin:

Most planes have a limit as to how high the wind speed can be for a given off angle from the runway heading. But, most landings aren't made with a 90 degree crosswind, either. In my glider days, I never flew if the wind was at 90 degrees to the runway. In powered planes, I kept in mind the plane's limitations, and my own.

There are two methods for making a crosswind landing: the crab and the wing-low. The vid shows the crab. The wing-low has the pilot lowering the up-wind wing, so that the plane "slips" into the wind, and opposite rudder is used to fly a straight course.

Getting on the runway is only part of the process. You still have the fly the plane after landing.

It may be that CoD doesn't model crosswinds very well, and the problem lies there, rather than with the pilot.

In the video I couldn't see any attempt to line up the plane with the runway before the wheels touched the ground.

If your still crabbing when you touchdown, the plane 'should' align itself (violently) with the direction of travel.

The ground handling in crosswind situations has always been problematic in the IL2 series, and I don't think it has improved much in CloD. I've tried crosswind landings after the initial release and the results were often rather weird when compared to e.g. FSX 3rd party addon aircraft.

Wind speed 15 is pretty high. When the clodo first came out we put wind into our maps and you could not even take off. The wind would spin your aircraft like a wether vain.

The value is in m's per second I believe.

hey guys...well i know about the landing procedures in crosswind situations...crabbing and low wing...i tried both methods...and the problem is not to get the plane to touchdown safely, but after a few seconds on roll out...it most of the time, the plane will tilt forwards all of a sudden, or one landing gear will break...
anyway, now i managed to land with a 90° degree crosswind of a strength of 15, but only with complete oposite rudder and the low wing almost shaving the grass on the runway...and then you will have to change rudder input at some point to avoid this tilt....

A value of 15 is over 50km/h, that's quite a gale for a small aircraft like a spitfire.

[droz]

set it to 5. Much more realistic.

Echoing the observations of the other posters here, the top of the scale (50m/sec) amounts to 180km/h winds. In other words, just because it's there doesn't mean it's realistic to use high values unless we want to simulate flying a Hurricane in a hurricane :grin:

I think that normal flying would be limited to winds up to 10m/sec or so. According to calculator in the website posted above, the 15m/sec value you mention is a 7 in the Beaufort scale, so it's probably normal to have difficulties landing in such a gale.

I suspect the reason we can set really high values is not for the prevailing winds but for the gusts. For example, having a 5m/sec wind that oocasionally gusts to 20m/secs. In such a case landings would be possible most of the time, but the occasional go around/missed approach might occur, just to make things interesting.

Also, we can set different wind layers. This could simulate the dangerous phenomenon of wind shear: big differences in wind speed and direction as you cross a specific altitude can result in equally big fluctuations in your indicated airspeed. And since the aircraft flies by what it "feels" on the wings (the IAS), this could result in a sudden stall (if you are flying into the wind and suddenly the wind starts blowing from your 6 in force) or overspeed condition (flying at your maximum permissible IAS with a tailwind, then suddenly you get a headwind of 30 knots or so and your IAS goes 30 knots over the structural limit).

It is for this exact reason that aircraft have speed limits in turbulent air, sudden changes of wind might push the IAS over the aircraft's tolerances. In civilian aircraft like the one's found in aeroclubs, the airspeed indicators also have these speed ranges clearly marked on the face of the dial with different colours.

Interesting stuff :grin:
