Hi guys,
I'm having a bit of trouble understanding what's going on in that report. Looking at figure 1, it looks like the aircraft captured the 9 degree glideslope, with a VS of 1400fpm.
My understanding is that when the GS is lost, the AP will continue in an "inertial mode" descent, with the associated failure flags. What I don't get is why the aircraft seemed to descend on a 3 degree slope, parallel to the GS, instead of the 9 degree slope that it had captured. Why wouldn't it continue at 9 degrees?
