True, we used to have a couple of airports with engine-out procedures that started at 50 feet with a 15 degree bank through 180 degrees of turn to avoid close-in high terrain. I believe the company makes the choice of what altitude they want(or is it the manufacturer?). Over the years on various aircraft, I have seen 400, 600, 800, and 1000 feet. But on the most recent aircrat with 1000 foot acc heights, there are specific runways with slightly higher atitudes. The interseting thing is that the OPT might adjust them slightly based on the final numbers as compared to the original calculation, so you might want to double check the acc altitude after getting the loadsheet numbers into the performance calculator.
