FYI - No such thing as CAT III A, B, or C anymore. As a matter of fact there hasn't been CAT III A, B or C for many years.
And yes, you are right about the expense, but that holds true for any operation.
You ask to explain how a management decision based mostly on economics has any relevance to pilot capabilities?
There is a lot to consider and it's very relevent to pilot capabilities vs the equipment on the property and the market(s) the aircraft is operated in.
If all training was equal across the boards you would be correct, but it's not. Neither is the mission various carriers have. You mention Horizon and Northwest. The Northwest DC-9 pilots have a different configuation in virtually every airplane they get into and Horizon operates in miserable weather all the time. The cost decisions work alongside the hiring profile and cross section of pilots hired along with the pool of applicants. But that's just the beginning. Choices of approaches to be trained to and which are included in the training program, will it be Part 61 or AQP? Is the air carrier able to take advantage of AQP or is the turnover rage so fast that it becomes ineffective? For small air carriers that have pilots with less hours and are learning the business more training is needed than a hiring pool with more experienced pilots.
Cost is always a factor, and pilot cabilities are always part of the equation.
B19,
Please reference your claim that CAT IIIa,b, & c does not exist anymore. I find it interesting as the AIM published in 2008 still refers to the differences between the three. Additionally, the sample of CAT III approach charts I have looked at still publish minimums for three sub-categories.
So ... You are saying that the current Delta MD-80 pilots are of a lower caliber then the pilots that used to fly the MD-80 for Swissair?! Unbelievable!
Someone as connected to management as you claim to be should know better. The decision should be based purely on economic necessity! Does the cost of training and equipment override the cost of operations without said qualification for the mission at hand. Let me ask you: Why do you believe most 121 ETOPS operators across the Atlantic choose to qualify its crews for CAT III operations? Is it a cost-benefit calculation; or, is it due to the superior capabilities of the pilots flying the Atlantic?
Your claim that such qualifications for smaller operators is prohibitive may or may not be true; however, there are smaller operators of one aircraft that have the qualifications!
