I have been getting into large jets more lately and most seem to cruise with about 5 degrees nose up attitude am I not balancing it properly? or is it a speed issue? or a altitude issue? or is that just how their suppost to cruise?

Reducing and balancing fuel in all tanks may help. Stan

Depends on weight, speed, altitude, pressure and GoG, but generally speaking, yes, they will all cruise ever so slightly nose up. Al
