I fly turnkey seismic all the time, and I have NEVER fudged the numbers to make the production work out... I do my job to the best of my abilities with Safety being my first concern, production comes second. I have never had an unhappy client and my production numbers always work out fine if the job was bid correctly. Bags per hour has more to do with how the job is co-ordinated than how the pilot flies unless he is completely green at production long line work. And yes on certain jobs, depending on the conditions and details, a hu500 and a B2 astar could have very similar cost per channel with a skilled driver on the stick. The 500 however would fly twice as many hours to do the same job, when both aircraft pay the pilot the same hourly rate, which one would you rather fly? <_<
