Further on the rudder/sideslip/super vs bug of the 737NG...

Recommended Posts

I would like to point out, because the problem has been raised on such a basis, that this weirdiness is not only sensed at FULL rudder deflection!The problem has it's effects too at low/moderate rudder deflections, like those we use when uncrabing on the final stages of a crosswind landing. Under such circumstances it results on the already mentioned sideslip towards upwind when one aligns with the rw centerline.This sort of things may basically have two sources:- Wrong definition of stability derivates;- Values being writen by via FSUIPC at wrong offsets.I am sure PMDG will soon find a fix!The following is a quote from Ron Freimuth's answer to my questions regarding this problem:---- Begining of quotation:Sounds like Vangelis' Yaw Damper or other system might be doing something funny. If variables are written to the wrong FSUIPC offsets or 'overun' the data length all sorts of things might happen. If handling is abnormal with no autopilot/YD the wrong values for Stability Derivatives, including related tables, can result in abnormal dynamics.Ron---- End of quotation.
