How does one determine "fuselage" level flight
On the ground? Or in the air? Doesn't level flight give the most efficient speed and economy. So airplane loading should be high priority. This is all based at cruse speed and efficient altitude. We can tell when wings are level by horizon or instruments . How do we tell when the airplane fuselage is level and the elevator isn't compensating for wing incidence or the trim isn't compensating for not level flight do to loading etc., forward CG causes elevator up to compensate.
This was bugging me after reading that most of our planes after time and equipment changes, the weight and balance is not very accurate. Some even say to place extra weight in baggage for better speed. So my thoughts were if we can determine what level flight is on the ground, then set a calibrated digital level in the cabin so when flying we could tell if we were at fuselage level flight, we could tell if we were flying level. Fly more efficiently...
Thought about checking the trim wheel center indicator to see when the trim fin is neutral position. But first you need to know what level flight is on the ground to calibrate. Elevator movement will also change trim settings.
Well this is what happens when the plane sets to long in the winter and the brain is rambling on.
Hope others are getting some air time.
