PROCEDURES

When an ILS approach is first selected and ‘loaded’ (or ‘activated’), the ILS frequency is automatically placed in the standby field. In order to fly the final course segment of the ILS approach, the pilot must place the ILS frequency in the active frequency field by pressing the VLOC Flip-flopKey. If this is not done, a ‘Select appropriate frequency for approach’ message appears within 3.0 nm of the FAF.

When flying a localizer-based approach (other than backcourse) with automatic CDI switching enabled:

GPS guidance is used while flying outbound and on the initial portion of the procedure turn.

VLOC guidance is used on the remainder of the approach from the time the pilot turns inbound on the procedure turn.

The localizer frequency must be active to use VLOC guidance.

When flying a localizer-based approach with automatic CDI switching disabled:

The pilot may select VLOC guidance at any point on the approach prior to reaching the FAF.

The localizer frequency must be active to use VLOC guidance.
