The same descent at 90kts needs 1900 RPM, same as you.<br /><br />On a precision approach I don't add flaps until I transition to landing speed, and event then rarely add more than 1 notch - with 7000 ft of concrete I don't really need all that drag, and I park at midfield anyway. Might as well let it roll out to the exit!D.B.https://www.blogger.com/profile/16311812701887962320noreply@blogger.comtag:blogger.com,1999:blog-19353992.post-24141452222542507492011-03-11T09:54:11.247-05:002011-03-11T09:54:11.247-05:0008Romeo fly well at 90 it just seems like slow mot...08Romeo fly well at 90 it just seems like slow motion and approaches take forever. <br /><br />For the most part I like that feeling, it's great to be ahead of the plane. I am going to work on keeping my speed up until just outside the FAF then configure for the 90 kts. Once I have the field I willadd flaps as needed.<br /><br />Here are my numbers...<br /><br />Approach level:<br />2200rpm, 90kts, lvl, no flaps, <br />My Precision Descent:<br />1900rpm, 90kts -5*, no flaps, -500ft/mn<br />NP Descent:<br />1600rpm, 90kts, -7*, no flaps, -900 ft/mnGaryhttps://www.blogger.com/profile/14637264267903131611noreply@blogger.comtag:blogger.com,1999:blog-19353992.post-2468465392988987922011-03-11T09:36:22.364-05:002011-03-11T09:36:22.364-05:00I don't know about 08R, but 49C does not like ...I don't know about 08R, but 49C does not like to fly at 90kts in level flight. The engine is doing about 2250 RPM, and it seems to set up an uncomfortable sympathetic resonance somewhere. And it wallows around in a very unhappy fashion, even more than at 80 kts and 2000 RPM, my normal downwind pattern setting. So I do most of my approach at 2400 RPM, and only slow down a minute or two prior to descending - about when the glideslope comes alive on a precision approach. Then I go to 1600 RPM which gives me 500 ft/min down, at 90kts, avoiding that awkward in-between zone.D.B.https://www.blogger.com/profile/16311812701887962320noreply@blogger.com
