Hi Jan,
Nose/plane rocking up and down severely, immediately upon initiating descent by VS (also with FLCH). The plane did descend, though. VNAV descent is still not working right for me.
Real weather, 290 knots, 107.7 lbs, CG 22.1. I haven't had a chance to do another flight today to provide pics/vid.
Something else I forgot about my initial flight KLAX-KLAS --> RNDRZ2 arrival to ILS 26L. At HOGOG, for the ils, the plane stayed on 083 heading and did not turn left to KODSE 020, nor left again at HUXAR 259 degrees. I went to HDG mode and tried to turn, to no avail, so I had to disconnect the AP and fly it manually.
Second flight KLAS-KLAX the straight in approach to 24R was ok...no 180 turn needed.
You may want to run those two test flights yourself: KLAX-OSHNN1 MISEN RNDRZ2 ILS26L KLAS, and KLAS-RADYR2 BLAQQ SHTNR ANJLL4 ILS24R KLAX. FL250 eastbound, FL240 westbound, real weather.
Thanks,
Jim
