Todd_F 38 Posted September 28, 2010 Share Posted September 28, 2010 How do I get the plane to use more than 86% power on take-off? It only seems to rev up after I manage to get off the ground. Thanks, -Todd Link to comment Share on other sites More sharing options...
jeffg 15 Posted September 29, 2010 Share Posted September 29, 2010 I just installed 1.20 and had the same problem.I was on the runway at KDEN and by the end of the runway I was only at 120 knots with flex t\o set to 56. JeffG Link to comment Share on other sites More sharing options...

JeffG That sounds like way too high a flex number. Remember that in the A32x FLEX (speaking very simplistically here) is a way of reducing wear and tear on the engine (think thermal cycling) by in essense giving you the thrust you'd get at the flex temp using TOGA. So if you want more power, use a lower FLEX temp. Consider the TOGA thrust at an actual 15C compated to 56C. Hope this helps. 1 Link to comment Share on other sites More sharing options...
jeffg 15 Posted September 29, 2010 Share Posted September 29, 2010 Herman, I am looking at Mike Ray's book The Unofficial Airbus A320 Simulator and Checkride Manual and on page 156 it says that the Flex temp must be greater than the outside air temp in celsius.I guess if you do not do a reduced thrust t\o no number should be placed in that area.

JeffG That's a good point. Mike Ray is great communicator and very knowledgeable. What you noted makes perfect sense, in that a lower temperature than ambient wouldn't result in any more thrust than TOGA. I should have added that to my comment. What I should have said is something like the lower the FLEX temperature, down to ambient, the more power you'll get at the "FLX/MCT" detent.

Todd_F 38 Posted September 30, 2010 Author Share Posted September 30, 2010 So if I leave the flex temp field empty I should get more power? My problem precisely is that when I go to take off no matter what I only get 86-87% power; regardless of the throttle detent(mct, flex, toga). As I am going down the runway power slowly decreases to around 84%. If* I manage to make it to 140kt I can get off the ground. Once in the air power quickly increases to 97-98%. Something about that just doesn't seem right. It has been this way since v1.0 -Todd Link to comment Share on other sites More sharing options...
Todd_F 38 Posted September 30, 2010 Author Share Posted September 30, 2010 Solved.... It was the to/flex field on the fmc. Leave it blank and the aircraft will give you all the power you need. -Todd Link to comment Share on other sites More sharing options...

I set flex temp and then T/O never reach the right % even if I give more power (TO/GA). Once airborne it encreases to full thrust... Anyway I will try to leave it blank and see what happens Thanks Link to comment Share on other sites More sharing options...
