1. Are there any implications of being trained in America? (different licenses etc.)
You can either choose to do your JAA licences in the USA (Not including the IR) or do the FAA licenses then convert them to JAA.
My personal opinion is to do the FAA licenses first at a FAA flight school, not the schools that provide JAA, they tend to be more expensive.
2. Am i able to get a VISA at 17 in America? or a working VISA or something similar for my training.
I don't know, try the US embassy website.
3. Does anybody know of a company in Florida are good for training with? (I want to go with a good flight school)
There are flight schools all over the USA, the best ones probably arnt in Florida, but I think Flight Safety Academy is suppost to be the best (also most expensive)
Best thing to do is get a list of schools that you would like to attend, and search for reviews on pprune, or jetcareers.com is usually better for FAA schools.
4. Is there anyway i am able to get a loan at 17? Are there special companies that help with this? e.g i dont begin paying the loan back until i finish my training.
You need to speek to a bank for this, I doubt you can though. Banks would usually look to see if you have something else to fall back on to, i.e. other work experience or qualifications. Since you are 17, you wont have any, other than GCSE's.
My advise would be go to college, get a job and get some life / work (money) experience behind you. When you're 21 - 22 start your flight training.
5. What is the average cost of being trained in the UK and being trained in USA?
UK - Integrated £60,000 - £80,000
Modular £35,000 - £55,000
USA - Modular £20,000 - £30,000
6. How long would it take from going from no license to a full professional license ready to join an airline company if i was training 3-4 days per week.
If you train in the USA, you will be training 6 days per week. 7 days if you include your own ground studies too (theres no time off) I'd says 18 months, including your ATPLS too.
7. And finally does anybody recognise these companies? If so please can you give some feedback on them good, bad anything is helpful.
I cant personally say anything about these schools as I havent been to them, but do a search theres loads of reviews.
