Depends on your situation.
But you need to remember that you will have large living expenses plus you may need to pay for a type rating.. so allow another 25 - 35k.
(before everyone starts bickering, I'm not saying it is the right or wrong thing to do, it is fact).
Routine all depends.
Groundschool is 5 days a week, 830 to 4:30 studying in class,
Get home and do another couple of hours and probs more at weekends.. for about 6 - 8 months.
Arizona, all depends on the instructor.
You'll spend a couple of hours prepping, couple of hours flying then a couple of hours backseating your flying partner. If you have an early morning flight, there is time to go get a tan by the pool, by it wears off.
You will fly 5 / 6 days a week and can't book leave.
You know when you are flying 2 days in advance.
The IR is similar.
But the flights are only announced at 14:00 the day before.
I ended up doing about one day of flying then one day off and so on. (so never really have 2 day weekends)
But again, depends on the instructor.
I found myself reading up / practising on the sims on days off though, which is a bit of a bore but it paid off for me and my flying partner in the end.
