In the event that manual flight is required and the AP/FD are not available (or turned off), the green desired track line will become a dashed green line and the solid green current aircraft track line will appear (this current aircraft track line is only available with both FDs off). By overlaying the current aircraft track line over the dashed desired track line, it is fairly straightforward to maintain the centerline on a TF leg. On an RF leg, keep the “cross” over the center of the track. The nose or the aircraft symbol can be used as a guide as well—by at least getting the nose of the aircraft symbol to touch the track line, the aircraft will be within RNP 0.3 tolerances (on the 10 mile scale). Continue to return to track until the “cross” is centered and maintain the path. On an RF leg, keep the “cross” over the center of the track. The nose or the aircraft symbol can be used as a guide as well—by at least getting the nose of the aircraft symbol to touch the track line, the aircraft will be within RNP 0.3 tolerances (on the 10 mile scale). Continue to return to track until the “cross” is centered and maintain the path. Whenever the aircraft is in FINAL APP, the descent rate is limited to -1800 fpm in CONF 0 or CONF 1 and -1200 fpm in CONF 2 or greater. If a greater descent rate is required, the airplane will drift above the path. The VDEV scale on the PFD is available during the descent and in FINAL APP. Full scale deflection is 200 feet and each dot represents 100 feet. The PF can also look at the PROG page and can see the digital readout of VDEV. From the VIP inbound, the aircraft must go-around if the airplane is greater than -75 (low) on the path. The PF can also look at the PROG page and can see the digital readout of VDEV. From the VIP inbound, the aircraft must go-around if the airplane is greater than -75 (low) on the path. If 1 X RNP XTK is reached the PNF should call-out “LDEV” and the PF must take corrective action. While evaluat
