Settings in Aerofly's main.mcf

This tool modifies the following settings in Aerofly's main.mcf:

<[tm_time_utc][time_utc][]      # Time is set in UTC
    <[int32][time_year][2016]>  # Year as four digit integer, can not be set in simulation
    <[int32][time_month][5]>    # Month as 1-2 digit integer, can not be set in simulation
    <[int32][time_day][20]>     # Day of month as 1-2 digit integer, can not be set in simulation
    <[float64][time_hours][0]>  # UTC time; minutes as fractions of 100/60
>
<[float64][visibility][0]>      # Percent, 0..1
<[tmsettings_wind][wind][]
    <[float64][strength][0]>             # Percent, 0..1, but can be set bigger than 1
    <[float64][direction_in_degree][0]>  # 0..359
    <[float64][turbulence][0]>           # Percent, 0..1
    <[float64][thermal_activity][0]>     # Percent, 0..1

<[tmsettings_clouds][clouds][]
    <[float64][cumulus_density][0]>            # Percent, 0..1
    <[float64][cumulus_height][0]>             # Percent, 0..1, but can be set bigger than 1
    <[float64][cumulus_mediocris_density][0]>  # see above, can not be set in simulation
    <[float64][cumulus_mediocris_height][0]>   # see above, can not be set in simulation
    <[float64][cirrus_height][0]>              # see above

Visibility

Visibility tests with METAR data, webcams and comparison with Aerofly FS 2/4 visibility show this pattern:

Visibility Real Life Visibility Aerofly FS 2/4
6,000 meters ~40%
7,500 meters ~50%

This in turn sets 100% visibility in Aerofly FS 2/4 to a real life visibility of 15,000 meters.

Wind

Setting the wind strength to 1 yields a wind speed of ~16 knots; setting it to 2 yields ~48 knots, and 4 yields ~160 knots. This implies an exponential function, which can be approximated by f(x) = 8 * (x + x^2), with x being the value set and f(x) returning the resulting wind speed in knots.

Turbulence causes the wind to change its direction of attack in Aerofly FS 2/4, as well as change its speed. The direct impact has not been measured yet.

The effect of thermal activity has not been measured yet.

Cloud height

Setting the cloud height to 1 yields a cloud height of 10.000 feet AGL as of Aerofly FS 4.
