I notice a couple of inches of level change, for example, when in descent at moderate 200 to 300 fpm range. I have a sight gauge on the day tank, and a small sump at the rear of it with the engine fuel take off line on the bottom. My SOP is to run my 12 gal day tank between 10.5 to 11 gals and 5 to 6 gal. Turn both Facet Pumps on at the same time, and time each pumping sequence. No selector valves, no retrimming the A/C due to uneven wing loading, and a very simple system to manage. I do have a high level warning sensor at about the 11 gal level, If I dope off. KISS, it works for me..The MT 3 blade "105" design is looking very good, more later after a few more hours..
