Realigning the IMUs would take something like 20 minutes alone (though it depends on the plane's current latitude).

- bronco21016 8y agoI’m currently working on an aircraft that has IMUs rather than AHRS/RNAV/GPS. I cannot recall ever seeing them take more than 5 minutes on first start up in the morning. Manuals specify 2.5-10 minutes. This is on a 1980s model. I’m sure newer designs are quicker.
