seems to me having been a full time flight instructor for 3 years before I got my north sea job, that whirlybirds figures are spot on, I earned about £20,000 3 years in a row and worked far harder for it than I ever have before or since. and I do not think it is high pay in fact is is less than average pay in the UK
given that someone deciding to become a flight instructor now will have to spend £60,000 and even in my day (late 90's) I had to spend nearly £40,000 that doesnt seem an unreasonable salary, given that I was working 6 days a week for ages and ages and never had a holiday because I couldnt afford to.
the Figures Bronx gave assume we can fly 40 hours revenue per week or 160+ per month, which is not achievable in the UK , I think I averaged 40 hours per month and once achieved 75 in July one year.
I think Bronx is out of touch and unrealistic and thinks everyone should have it really crap cos he did when he was lad !
