The-sky-captain Posted May 8, 2009 Report Posted May 8, 2009 Going from POH memory the rotation speed of my "J" is around 63 knots. For whatever reason my plane is never ready to fly until about 72 knots. I've experimented with flap and trim settings but not much changes. All of the other V speeds are right where they need to be. Any imput? Quote
The-sky-captain Posted May 8, 2009 Author Report Posted May 8, 2009 OK, that's about where I leave the ground too. I can get it off the ground at around 63k but it just doesn't "feel right." Thanks for the input Jim. Quote
fantom Posted May 10, 2009 Report Posted May 10, 2009 60 kts and light back pressure; liftoff, stay in ground effect for another few seconds; and off you go. Check you gross weight, flap setting and POH. 72 kts. is, in my experience to fast, and can cause you to sit on your nose gear. Maybe an hour or two with a Mooney savvy CFI will help. In any event: RTPOH 1 Quote
RobertoTohme Posted May 10, 2009 Report Posted May 10, 2009 Gary, On the "Emergecies" chapter of the POH you're reading in the picture, do you get a lot of "if unsuccessful, pull the eject handle"? Just curious... 1 Quote

TimBo Posted January 28, 2021 Report Posted January 28, 2021 62 ktas ~ 72 mph, M20C shows air speed in mph. I think you all are right Quote
TimBo Posted January 28, 2021 Report Posted January 28, 2021 63 kts = 72 mph, mooneys (M20C) show indicated airspeed in mph on the outside and kts on the inside of the gauge. Be sure you're reading the correct units Quote

MooneyMitch Posted January 28, 2021 Report Posted January 28, 2021 Do small planes really rotate? Maybe I missed the Vr in my old POH. Or maybe I'm old and missed the Vr in my POH ! 1 Quote

Be sure you're reading the correct units My Owners Manual says to pull back on the yoke at 65-75 mph. So I generally pull back to 70 mph, 75 if I'm heavy or the wind is pretty gusty. It works for me and my C. Quote
FlyingDude Posted January 29, 2021 Report Posted January 29, 2021 (edited) Is your cg proper? Did it drift forward over the years as a result of mods and replacements? A forward cg plane rotates at a higher speed than an aft cg plane... Edited January 29, 2021 by FlyingDude Quote
RobertGary1 Posted January 29, 2021 Report Posted January 29, 2021 Yea when heavy you want more than 63. Quote
carusoam Posted January 29, 2021 Report Posted January 29, 2021 Welcome aboard Timbo! I think these guys are alright too... @The-sky-captain Hasn’t been back since just after he sold Rocky... To restart the old flame... Did you use T/O flaps with those numbers? My engine runs turbine smooth... So I use a progressive method of rotating... It happens so fast... I just skip to the flying check list... Use caution with the soft field technique... it is really easy to lift off easy as expected... but climbing out of ground affect without accelerating can be a bit funky... PP thoughts only, not a CFI... Best regards, -a- 1 Quote

The spees that I pull back on the yoke to leave the ground doesn't change with flap usage (most often none), only with load and winds. 1 Quote
MatthiasArnold Posted January 29, 2021 Report Posted January 29, 2021 Just looked up the T/O speed of some recent flights with my M20R O2 on CloudAhoy. The T/O speeds are all in the range 62 .. 65kts (mostly depending on TOM and DA). Best, Matthias 1 Quote
Releew Posted February 3, 2021 Report Posted February 3, 2021 I apply backpressure at ~65K. From there, I let the plane fly itself off the runway. Obviously the trim needs to be set correctly. With Three "Full Size" passengers and half tanks she breaks ground at 70-75K and quickly accelerates to 90K plus for initial climb. I've used this method for every airplane flown. Not a lot, but enough. Rick 1 Quote
