bleed air Posted July 16, 2009 Report Share Posted July 16, 2009 Good discussion, folks. Thank you. I'd like to add a little clarification if I may. Skids-Up – “Surely we realize that if we do not know what the charts say, it doesn't matter where they are...” Absolutely True! Chopper_guy – “Who cares where the performance data is located? Performance data is REAL. Any pilot who ignores the hover-out-of-ground-effect chart in the mountains, or anywhere, is flying in uncharted waters. However, everyone who has flown drills knows that all kinds of crap gets added after the first loads. You can get an overgross load up under good conditions, not learn that you have a tiger by the tail until it too late to put it back down, and be way over your head putting it down under bad conditions.” Also True! CJM91 – “As for the performance charts, it shouldn't matter where they are. The Gross Weight limit is already in the Limitations Section. I don't think that the Performance Charts could be considered limiting as there are other local site variables that are difficult to quantify or change from load to load (wind, humidity, etc.). They certainly should be a guide, though.” Agreed. However, after several years of conducting PPC’s , it’s been my experience that most if not all reasonably experienced pilots can quote the TQ, Temp and Gross Weight Limits almost in their sleep, but given a fairly straight forward scenario where a weight & balance calculation and check of the performance chart is required…well,… it often turns into quite an exercise. We seem to know the Limitations Section like the back of our hands (if we don’t, we should!) On some level, most of us have some understanding that by exceeding the numbers in the Limitation Section we are doing something wrong, if not illegal, and that there could be real consequences if things should go sideways. So, would it hurt then to put the performance charts in the Limitations Section? Maybe more of us would then realize that 200+ lbs over gross and 500+ lbs over HOGE is really not a good place to be. That way we wouldn’t have to rely on the machine to “talk” to us because, apparently, some of us are still not getting that message. Quote Link to comment Share on other sites More sharing options...
