The ''Tile selection mode'' specifies how tiles are automatically generated once the aircraft reaches the border of the original tile. It is a good idea to leave this setting as you find it, because it's automatically set when a scenario or METAR is selected. For those who dare, here's an explanation of the options: | The ''Tile selection mode'' specifies how tiles are automatically generated once the aircraft reaches the border of the original tile.

* ''aloft waypoints'' is like the above, but lets you specify many positions (called here "waypoints") and AW will interpolate them in the 3D space. In METAR mode it works automatically and, instead of using the user data, it guesses the vertical distribution of winds on its own based on the reported ground wind, especially using as waypoints the live METAR stations. | * ''aloft waypoints'' is like the above, but lets you specify many positions (called here "waypoints") and AW will interpolate them in the 3D space.

Finally, the ''Wind Configuration'' dialog, reachable with the button at the bottom, is the one used by the ''aloft'' wind models. It should be self explaining, but remember to set at least one waypoint if you want to use ''aloft waypoints'' in non-METAR mode. Also, the value for level ''zero'' is not meant to be ground level, but the lowest aloft layer, i.e. the one just above the boundary layer. | Finally, the ''Wind Configuration'' dialog, reachable with the button at the bottom, is the one used by the ''aloft'' wind models.

This dialog is especially uncomfortable with waypoints, because that mode is intended for use with [[Howto: Fetch live aloft data|live aloft wind data]], that someday might become available (again.) | ||
Note that the boundary layer is always calculated, but is less realistic without terrain effects. | |||
