I'm not. Much of instrument flight is watching instruments, following
procedures, and other activities that can be very accurately simulated. It's

Incorrect statement. Learning to fly on instruments also entails
learning to firmly shut out the "seat of the pants" sensations. The
"seat of the pants" sensations are not there when flying a desktop
computer so its incorrect to say that instrument flying can be
"accurately simulated" on a desktop. Only when you fly a real airplane
on instruments can you fully learn to ignore the often contradicatory
sensory input from the movements of the airplane.
