It is about the number I am seeing as well
That's very close to conclusion I've made reading figures from other TB20 owners - it seems that I'm few knots slower with full TKS. However, it's not worth of mentioning - when I transfer it to my usual flights 2-3 hours, it's few minutes of difference. Usualy, I'm more influenced by the winds which somehow always blow as headwinds.
What do you prefer: to stay on the ground due to bad weather but with potentially 3-5 knots more speed or to be able to fly more often and handle some ice but loose some speed in the process.

The answer is obvious increase dispatch rate.

Was thinking exactly the same thing, you would lose far more effective speed due to weather, ice etc.
I wouldn't argue "3-5kt" is a price worth paying for not getting iced up, but I am suprised it is as much as that on the TB20.
However, there are TB20s which for an unknown reason fly 3-5kt slower anyway
I guess if they are French built aircraft finished after lunch on a Friday.....
No comments on Jason's Post. ;o) How much weight does the TKS system add to the aircaft? Couldn't it be an explanation of some the speed loss?
Sorry, Thierry, as an Australian, I think the same would apply to any UK built aircraft but of course nothing is manufactured in the UK any more!
The 50kg extra weight of the TKS system cannot explain a 5kt speed loss. The TB20 speed hardly varies with weight.
