Visit the ATOs that you have listed before deciding.
I see from a previous post that you are aged 53 this month. Whilst that is just a number, the majority of airlines don’t take that pragmatic view.
Historically aged 40 was the cut off to go jet & that is with previous turboprop experience. You are deemed by virtue of age to be a training risk & will possibly be required to fund any type rating.
Having said that, the MCC/APS course will be the hardest training to date. The learning curve will be steep. Only punctilious preparation on your part will produce satisfactory progress. The HoT will be totally honest as to your prospects if you ask the right Q.
Turboprop operators are your best bet. Loganair or similar but as you can’t / won’t relocate your options are even more limited?
Always interested in feedback post APS completion.
