CapnDave Posted November 17, 2013 Report Posted November 17, 2013 I haven't seen any other posts on this, so if I missed one I apologize in advance. The checklist says that MP should max at 45" and the RPM at 2700 for runup and takeoff. At sea level I only get 43.5" and 2100 RPM. I use a CH yoke and made sure that it was calibrated properly. Any other ideas? BTW it's not that I can't get it off the ground or anything. Takeoff roll is a little bit longer than I would expect, but climbout and cruise are fine. I just wonder if there are other things that might also be affected. Thanks!
Goran_M Posted November 17, 2013 Report Posted November 17, 2013 (edited) What are the weather conditions?Hot? Cold? Humid? Dry? ISA?Also, the take off roll has been verified by a DC-3 pilot as being "Pretty accurate, give or take a couple of feet". Edited November 17, 2013 by Goran_M
CapnDave Posted November 18, 2013 Author Report Posted November 18, 2013 It was cold, about -5C IIRC. I just tried it again on a standard day (temp 15C, 29.92" hg) and the numbers were 44" MP and 2200 RPM. I'm not questioning the takeoff roll, although I worded it badly (sorry!). The aircraft seemed to perform about as expected in climb and cruise. All I'm wondering is if this is anything to be concerned about. If not, fine. The plane is still fun to fly. Just wondering, that's all. Thanks again for the quick response.
