Today I’ve been playing around with ActiveSky’s Thermal creating tool today, but don’t really have any idea what I’m really doing.
For those who don’t know, you place your aircraft in whatever position you want to see a thermal, switch to the Active Sky window and hit the create a thermal button… so I’ve set up one at the mouth of the Grey River at Greymouth with my sailplane in slew at 900ft.
It automatically updates, so I unpaused and was able to circle up to 2500 feet before I started wondering what the ceiling was, and opened the ‘thermals.txt’ file to find out. This is the code I had generated:
<Thermal>
ID = greymouth
Lat = -42.4470
Lon = 171.2172
Type = Temperature
Size = 0.9
VertComponent = 2
Decay = 10
BaseAlt = 229
UpperAlt = 1033
It says the ceiling is 1033 feet and the base is 229 feet, contrariety to the description of the Active Sky v6 read me file. Can anyone give me more detailed instructions for ‘soaring’ with FS2004, or explain the above code?
Also, what exactly does the 'Type = Temperature' line define, what are the size, VertComponent measured in? What exactly is the 'Decay' and can anyone reccomend me some decent freeware glider's to download?
Cheers!
