It would be interesting to factor in the actual time "on duty" plus any retainer when working out "Hourly" rate
From my example "minimum wage" is not something that is applied for FI jobs
Not unusual to work 10 hours and only fly 3
Lets say £60 (before tax) deduct travel costs £50 and divide by 10 = £5 hour - Looks like I just made it on an average day ! and that's on a "reasonable" hourly flying rate. If it rains then lets hope it stays wet all day and I only loose my time and £10 petrol money.
Now lets compare to car mechanics and plumbers who charge £80 an hour which is much more sensible if you want to pay the bills and make some profit!
Anyway must dash as I have a 6 month £150 quid medical to attend (no wonder my wife thinks I am nuts).
