That makes sense. I've confirmed that there is no additional requirement in our op specs either.

You guys have waaayyy to much time...

No doubt. It was a really, really long flight.

Kinda hard to remain clear of clouds on an ILS, LOC, LDA, VOR, NDB, or GPS approach in IMC. Just saying.

Sorry, I should've clarified. As with all visual based approaches on an IFR flight plan (Contact, Visual, Circling) and the visual segments of instrument approaches (below DA/MDA)

Look at the cat D and higher minimums for circling approaches. The visibility exceeds the visibility required for a visual approach due to the turn radius required at higher speeds.

If your airline opspecs or the manufacturer classify your A/C type as cat D (CRJ200s) there is no sense in training the maneuver since cat D minimums will push the approach into the visual approach category.

I worked at an airline that, for a short time, sold CRJ200 type ratings to people and then hired the ones they felt were competent. The training was done outside of the airline's training program and so they trained the circling maneuver. These pilots were issued unrestricted type ratings. At the same time pilots going through the same training inside the airline program were not trained on the maneuver and were issued restricted types.

If you are issued an ATP through an air carrier program with the VMC circle to land restriction, you are limited to 1000/3. You will find this within one of your regulatory (FAA approved) manuals. You will see no lower than published MDA or 1000ft and 3 miles above airport elevation to derive legal mins. If you are issued an unrestricted type without the circling you will see the verbiage to only be mins for your approach category of aircraft.

Finally, someone gets it!

C075 is the governing OpSpec. Each company has specific limitations approved therein. Your company's FOM, FCOM FOTM or whatever your company procedures manual is named should have a description of the requirements, limitations and procedures for complying with C075.
