Does anyone ever have this problem or solution?It seems when landing on a runway where the threshold is just off a coast (water), when I cross the coastline,the plane immediately slams into the ground. It happens with many planes but not all the time. It is not a weather issue, or a stalling issue (as I am well above the stall speed). I am at 150' agl crossing the coastline, the runway is ahead by only several feet, and them I am slammed into the runway. (I lose 150' in 1 milasecond - impossible!) It happens at LGA 22 (over water approach) as well as other coastal runways. Any solutions?Paul Gugliotta

Update to this: I also notice when I take off from the same runway in the opposite direction (takeoff over the coast line) I am immedately thrown upwards by 400' as I cross the coast line at say 50'. It happens with the LD767 and PDMG 747. It appears the elevation of the terrain is being fooled at these points. I am surprised no one ever reported this or has even answered my posting after several posts in other sites.Paul Gugliotta

Change the mesh resolution in your FSX settings. I had the same problem, but it went away after tweaking the mesh

OK thanks,that did the trick. I had mesh at 10M, I moved o\it to 1M and it still happened, so I backed it off to 300M and no sudden altitude shifts. Now I need to work back to 10M to see the optimal setting. What mesh resolution do you use? ( noticed - evenm though I set it to 10M, it defaults back to 19M)

I had to rebuild my fsx.cfg a few days ago and there's a very slight chance that I didnt get the mesh resolution correctly, but I have it set to 5m. I think that texture resolution affects the mesh resolution, so if youre using certain texture resolutions you are restricted to certain mesh resolutions as well. I _think_. Dont quote me on it :(

I am pretty certain mesh and texture resolution are independent of each other. Another thing I have noticed is with the max mesh resolution set, that float aircraft tend to bounce around randomly when they are floating in the water. I've had no problems with anything 10m or lower resolution.
