I’m sure you will be fine, more so if you have experienced flying a small aircraft, you will note the experience is somewhat different to going on holiday on 737. I wasn’t trying to put you off, it doesn’t matter to me one bit – I was merely generalising, pointing out to those who intend completing a PPL to first have a trial flight prior to block booking.
Your timeframe is easily achievable within 6 months, as long as you intend training intensively during your onshore period, as the weather will play some part in your training.
I worked for Philips Petroleum Co Norway on the Ekofisk Field – I gave that up for much of the same reason ‘Boring’, once the novelty factor wore off, it was the same thing over and over for 14 days at a time, ended up more like a prison sentence that you received payment for, albeit, the money was rather good!
Best of luck!
