On the wings cadet course you will find that it is a full time approved training course.
In Southampton you will spend about 5 months of Mon-Fri 9am to 5 pm classroom (including CBT) training. There will also be a significant level of self study, some of which will be on premises and some of which will be home study.
You will then spend around 7 months in New Zealand doing your flight training.
Following this is 2 months of full time UK instrument rating training and examination, at Bournemouth.
Then there follows the intermediate phase of airline based (MCC) training known as the Airline qualification course. This takes around 3 weeks.
Then follows the advanced training leading towards (and in conjunction with) airline placement. This only happens once placements are established. It may involve a long wait for such a placement depending on the opportunities available at any given point in time. These placements are not uniform in nature or in the terms of appointment. Some may involve significant levels of additional expense for type rating training, and some may involve no additional expense.
It would be realistically impossible to do such a course whilst holding down any other major form of employment. The course is a full time vocation for at least 18 months.
Your accomodation is provided within the course costs (or training bond as it would be referred to.) This is usually in shared rental property in Southampton and Bournemouth during the respective training phases. In New Zealand, it is in purpose built, single room, halls of residence style accomodation a few miles from the training facility at Hamilton airport.
Food/transport and other ancilliary costs (including insurances, security bonds, and other living expenses) are down to you. Depending on your own circumstances, that figure probably benchmarks around £10,000.
The training costs are not "£60,000" They are around a base figure of £80,000. The Training bond is a basic £69,000 but on top of this (and to some extent dependant upon your previous flying experience,) there is an additional foundation course to pay for, which (depending on the exchange rate) is around another £10,500. The $NZ is currently very strong against sterling, the Euro, and the US Dollar. It has appreciated about 20% in the last year alone, and that is from a very strong base even then.
You should therefore plan on a minimum budget of around £90,000 - £95,000. You might also want to earmark an additional £7,000-£10,000 for possible extra type rating costs at completion of the intermediate (ACQ) phase.
You would be well advised to start by reading the CTC website, where much of this information can be found. In any event, I hope this is helpful.
