Yes, the Horizon fleet is well equipped for the amount of actual "down to minimums" approaches. We have a box where the field elevation/runway length is entered to provide the captain "flare symbology" on the HGS(flight dynamics). We have to have all 3 nav's tuned to the localizer(at least in the Q400). Also included is Inertial Navigation System. That's the only type of equipment we have.
The Q400 and the CRJ are both certified for Single-Engine CAT IIIa operations. This provides a lot of relief when planning for T/O alternates.
Most of the approaches are 50' MDA/600 RVR. Takeoff minimums with CAT III capabilities allows for as little as 300 RVR.
And that's all I know.
