From the approach plate we see that we now need to be at 2500Ft at HITAK and we have set the altitude
bug to 2500 ft. The AP/FD vertical is still in ARM waiting for vertical guidance from the 430W.
After passing HITAK we start getting vertical guidance from the 430W and it switches from Vertical ARM to
Vertical NAV. At this point the AP/FD will hold altitude until the vertical deviation indicator is centered. Once
the VDI is centered, the AP/FD will capture the glide-slope and hold it centered while descending.
