Note: If desired, one attempt may be made to realign a faulty IRS (light steady) in ATT
mode by setting the IR MODE rotsel to OFF, then to ATT. However, in this case, the
ATT HDG SWTG rotsel must be in the same position as the AIR DATA SWTG rotsel
during the reset, to prevent the flight controls from temporarily reverting to alternate
law, and to avoid autopilot/autothrust disconnection.
