I posted this in another old thread but getting no response. I never paid attention to this as I depend on the hud but how do you calibrate the HSI such that the red warning flags are gone? In the other post, it said you have to wait for spin up (guessing gyro) but I sit there on the runway forever and the red flags don't go away. Also, the HSI seems to be completely out of sync with the director circle.
Thanks.
