November 3, 200223 yr Hi to all, i am currently experiencing a problem with the PIC/POSKY763 model on landings. During the flare which I initiate around 20 ft the airplane absolutely refuses to land- it justs floats and starts to climb for a few seconds before it finally settls onto its main gear. I have experienced cutting the throttle to idle at 50 ft but it doesn't seem to solve anything. can any real world pilots out there help me to correct this problem as right now it is a real pain in the #$%@ and I won't fly this aircraft anymore until I can fix this problem, thanks.
November 3, 200223 yr You are ballooning, something I know all too well from learning to land a real C172. Simply put, you are pulling up too much. I believe it should be only a few degree pitch up for PIC.I have read many times that you do not flare a jet like you do a light GA aircraft. You do not fly level down the runway a foot off and stall it onto the mains. Do a few autolands and watch what the autopilot does.Does anyone know what a typical descent rate is for a 767 at touchdown? 100fpm?Lee Hetherington (KBED)
November 3, 200223 yr Also, are you using the VFR view? You want to pull up to much beause your perspective looks really nose down. Try looking at the far end of the runway. Regards,

November 4, 200223 yr I always keeping 600fpm while passing the runway threshold then idle thrust at 50 feets then just pull up very slightly to 200fpm or even less, normally can have a soft touch down..Gooper....i suggest you confirm your approach speed+ another 5 next time, pull your yoke gently after idle the thrust~ Don't tell me you don't fly it anymore, otherwise your problem can never be solved!
November 4, 200223 yr Gooper,As the guys says, you're either too fast or pulling back too much. Always check the INIT/REF page for your Vref speeds, and more or less stick to them using the Vref + 5 knots rule (it's more complicated in real life, but let's not go there). You only need a very gentle pull on your joystick to flare the 767. I will normally flare when the "20 feet" call is made, simultaneously retarding the throttles to idle. Works every time. If my landings are bad, and they frequently are :) , it's not because there's something wrong with PIC but rather my flying technique. Don't be afraid to haul the mother in at around 140 kts with flaps 25. Weight, weather and runway length permitting.Don't dish 767PIC, you ain't gonna find anything better.
November 4, 200223 yr Hi,Here's how to do it:1. Fly your approach at Vref30 + 5kt (I don't want to get into the more complicated IRL "approaches" concerning the speeds, just do this)(2. Slow down to Vref before threshold if it's not windy)3. If your weight & speed are in the correct regime (i.e. the Vref actually matches your LW, it will if it's taken from the FMC), then your attitude @ Vref30+5 should be ~ 2.5 degrees ANU4. Hold the constant glideslope steady all the way to 30ft AGL where you will GRADUALLY pull the throttles back to idle (correct way is to be at idle at 10ft AGL), AND at the same time pull aircraft nose to ~ 5 degrees ANU (not much more, tailstrike danger!).5. HOLD the 5 deg. ANU + throttles @ idle -configuration until touchdown.WORKS EVERY TIME!Happy landings!Tero PPL(A)
