Section 4
Normal Procedures
If the VNV softkey is pressed more than 5
minutes before the top of descent (TOD) or
the altitude preselect is not reset to a lower
altitude, VPTH will begin to flash inverse
video (white/black) when the aural "Vertical
Track" alert sounds 1 minute prior to TOD.
Pressing the VNV softkey and/or resetting
the altitude preselect to a lower altitude
cancels the flashing VPTH and the autopi-
lot will capture and track the vertical profile.
If the VNV softkey is not pressed, or the
altitude preselect is not reset to a lower alti-
tude, VPTH stops flashing at the TOD and
the airplane will remain in ALT mode and
not descend.
