Hi Ulrich,

How good is RCU?? Almost instance response to help you trouble shoot your fuel system.

I agree that a UAT or a CAT is not always necessary, and a lot of people successfully operate a turbine with out one.

However, look at it this way. If you did not have a CAT fitted, you may never have picked up the air leak that you already had. So your CAT has already done a sterling job for you.

I am in favour of air traps. I make it a habit to check my UAT after every flight. If the air bubble is excessively large, this is a sign that a air leak may have developed up stream. They also make a great final filter..
