TKS endurance
45 mins at max rate and 1.5h at normal rate.
the max you can get into the tank is 6.3usg.
Nice to have it at this time of year, I go through approx 20L per annum with my TKS equiped ovation 2. Most of my usage is between Nov and Feb but I have used it even in July/August.
Beware that the prop modifications will slow you down a little - 10 kts or so (the titanium strips on wings/empennage make hardly any difference to the aerofoil and the factory pilots blame most of the speed reduction on the prop).
What model do you have and how much are they quoting for the retrofit?
