To change the navigation source to follow the FMS flight plan you currently have to press the NAV/BRG button

  • After selecting the right source on your side make sure the white arrow is pointing to your side (can be changed with the CPL button).
  • Then push NAV to arm the capture (When you are close to the route it will engage FMS lateral steering and follow the route.)
  • There is no VNAV climb installed in our King air, so climb with PITCH, VS or FLC.(Descent with VS, FLC or VNAV)
  • Then change source to NAV1 or NAV2 (depending on where you entered the ILS frequency) and then push APPR to fly the approach.
  • You can also leave it in FMS source and push approach but that will give you an non precision approach.
