CAT II guidance and minima

CAT II requirements

Check category and minimums.

Horizontal cue: localizer

Vertical cue: glideslope

Identify the approach category, charted minimums and aircraft equipment required for the simulated operation.

Check the setup

For CAT II, set the same RA minimum on both PFDs and tune both NAV receivers to the ILS frequency and course. Check valid NAV indications on both sides. FSS lists FLAPS 5 for CAT II. The displays do not flag different minimum values, so compare the numbers yourself.

Read the approach status

For CAT II, engage AP and yaw damper and check white APPR 2 before glideslope capture. FSS also lists valid independent sources, no relevant miscompares and STEEP not armed or engaged; it describes an 800 ft radio-altitude capability freeze. White is armed and green is engaged. If APPR 2 is unavailable, reassess; do not continue as a CAT II approach.

Confirm LOC and GS

Watch the lateral and vertical FMA and actual deviations as the signals capture.

CAT I limits

For CAT I, FSS calls for BARO minimums and autopilot disconnection before 200 ft AGL. The FSS FMA page separately describes AUTOLAND status logic; verify the capability and its limits in your installed build.

APPR 2 status

A capability label does not replace monitoring, landing preparation or the missed-approach decision. ^{[9, 167, 215] [167] [10]}
