Or even better, don't use the UAT at all because it is giving you NO extra benefit and only trouble. Here in germany most pilots are not using the UAT at all and the ones I know only had it for some flights because it causes trouble (bleed air, leaks's)
Use a standard Hopper tank, and felt clunks in your main tanks. This is more safe. All european manufacturers don't recommend the UAT.
This is just my experience and not mandatory!
Andreas nows best
we have build over 50 models incl a uat never had any issues.
we have sold a few more even last year can tell how many
if you have no idea in how to make a fuel system then this answer is a perfect one.
i now of many cases where the uat saved the flight.
however i DO see a lot of festo connections that have not been cut properly , they need to be cut abolutely strait!
otherwise they will leak!.
andreas you have no idea what you are on about.
i give UAT standard with our turbines.
infact these are the best fuel filters in the world , i dont even use fuelfilters anymore after the uat no need for them.
