surface wind ?

  • Noticed that the maximum wind speed is around 35kts but unfortunately for some reason these 35kts are only at 500ft.
    Below 500ft the wind speed dramatically reduces by more than 50% and on ground it's just a 16kts breezes so it's not possible to practice e.g. challenging crosswind landings.
    Although wind speed generally reduces at lower altiudes it shouldn't be that much of a reduction.
    Furthermore if IPACS already simulates a reduction in speed, the correct change in direction would be nice if it would be included.

  • Theoretically due to friction and the ground boundary layer the wind speed at the ground is zero. The windspeed then increases very quickly with altitude and then stabalizes at the edge of the boundary layer which can be couple hundret meters to multiple kilometers high depending on the ground shape and roughness.
    This wind profile is well modelled, you can observe similar drops in windspeeds in the real world even though on a flat airfield its probably not as pronounced as in the Aerofly FS 2 currently. Also there are other effects in the local wind system that the Aerofly FS 2 currently does not model, which can result in higher surface windspeeds. For example down drafts or strong local gusts, windshear, wake from other aircraft...

    So what we really need is higher overall windspeed, so that the surface wind is also stronger. And maybe it would be good to change the thickness of the boundary layer locally, have a larger boundary layer in the mountains than in the flat land or even near the ocean or desert where there are only very few obstacles that slow down the air near the ground

  • Could the wind in the descent have some variation in speed and direction? Jeppesen FlitePro from about the year 2000 had this and it made an ILS approach more authentic i.e. hard work. I think FlitePro varied the wind with about every 200 or 300 feet of descent. Perhaps +/- up to 25% of speed and 25 degrees of direction would work?
