DA40 fuselage static ports / G1000 not in AFM I’m a flight instructor who just switched from instructing in 172’s to flying the Diamond DA40 and am confused about a few things. Our DA40 has two static ports, one on either side of the fuselage. This doesn’t make sense to me because the AFM in the airplane says the static ports are on the left wing along with the pitot probe. I haven’t been able to find anything online about these static ports, and I’ve only seen one DA40 AFM. 

My second confusion is, the airplane is equipped with a G1000; however, the AFM in the airplane doesn’t say anything about the G1000, there is only a cockpit reference guide for it. Would this indicate an upgrade from original avionics? Would it be in the maintenance records? (Mx records was my next stop)
I found the answer by further reading the AFM. On DA40's with an auto pilot installed, optional static ports may be added to the fuselage.
