Xnr,
why do you consider the requirement for a 'true cat A' from TC as a problem?
Wouldn't it be nice if you could fly a slightly more potent machine, thus increasing the safety aspect?
I understand it would be hard for any company to upgrade an entire fleet, but I think it will be just a matter of time before TC starts following JAR Op's and starts imposing higher limits.
Yes it will lead to a lot of complaining, but I'm sure the crews actually flying the machines will feel pretty good about it.
Flying to an elevated rooftop less than 100' square, in an A model at +30C weather with 5 on board, some cargo and fuel is just not as safe as it should be. Now you can train all you want for the 'unlikely event' of an engine failure in these conditions, but know that the day an engine quits on the final stage of your approach to a pad in such conditions, you better be right on the numbers, as there will be no margin of error.
Of course some of the aviation gods will dispute this because this will A: never happen to them and B: they can deal with such emergencies at any time.
Of course that's just my opinion, I could be wrong.
