Are you also able to list all conditions (restrictions, limitations) that are aplied at Tyrollean regarding the operation of both series by the same pilots? Like: Minimum TT in one type, rest period between switching types, etc.
I flew the Q300 and Q400 at Tyrolean (Austrian arrows) and there was one restriction to fly both aircraft.
Most ppl started on the Q300 and after 8 months (400/500 hrs) you did your transition to the Q400. Some started on the Q400 and after 500 hrs they did the transition to the Q300, wich is harder (used to glass cockpit, higher speeds, ect.)
Rest period between types? hahaha
NO. You can fly both types in one duty.
Mostly you start on one type and you do a flight on the other and stop. Sometimes you fly the 300 then the 400 and the last leg on the 300 again. No problem what so ever.
The aircraft are different but I never had a problem with flying both of them, nor did 90% of the colleagues. Good SOP's and training is realy important, but that is something wich is realy good at Tyrolean.
I wish I was still flying there, its a good company!
on the other question:
3- Although you consider this kind of operation feasible, wouldn't you find it safer if both aircraft were flown as two independent fleets? Especially in places where conditions can be harder than normal, i.e. short runways (eventually wet), strong crosswinds with associated turbulance...
we flew both types into Innsbruck, Bolzano, and other special cat C airfields.
You should be aware of the type you are flying when you go there.
But because you fly both types realy often, it's no problem.
Again good training and SOP's are realy important!
The only problem you can encounter flying both types is good SOP's!
I hope you have a good answer to your questions.
Kind regards.
