lownslow Posted April 21, 2008 Share Posted April 21, 2008 Ok, here is a question for all of you Engineer\'s out there... On the four engine Time, Fuel and Distance to climb charts there is a Temp Dev correction on the third page, I believe, for an all bleed on condition. The baseline is -30. Anyone have any idea why the base line is -30 instead of 0? The three engine climb charts don\'t have this correction, I assume because they assume you are bleeds closed. Ideas?

AMPTestFE Posted April 22, 2008 Share Posted April 22, 2008 Of course, the answer is right in front of you! The flight performance manual is flawed! Seriously, I can\'t tell you I\'ve ever noticed that. How was Vegas? Quote Link to comment Share on other sites More sharing options...

NATOPS1 Posted May 14, 2008 Share Posted May 14, 2008 I took a look at the charts mentioned what if... I hate when pepole say that but here goes.... What if the baseline value should be 0 not -30 and then you correct up or down for non standard day temps? A colder day would \"bleed\" less energy (very small change from baseline) and cause a better(reduction)time to climb and a hotter day would bleed more energy and would result in a slower time to climb...right? I agree with you on the 3 eng chart bleeds would be off that is if you got permission to do a three engine TO... Quote Link to comment Share on other sites More sharing options...
