   * 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.
