Approach Basics (GX50/60)

Approach Transition

Approach Transition operations occur after you enable approach operation. The APPRCH annunciator will turn on. The CDI sensitivity will gradually scale from

5.0to 1.0 nm full scale per side automatically. The IAF is usually in the Approach Transition operation area. The ACTIVE annunciator will start flashing when you are within 3 nm inbound to the FAF and not on hold (sequencing suspended). When you are 2 nm from the FAF, CDI sensitivity will gradually scale from 1.0 to

0.3nm full scale per side automatically.Approach Active

Approach Active operation begins when you cross the FAF and ends when you cross the MAP. The CDI is at 0.3 nm full scale per side. The OBS/HOLD Annunciator is on steady. The ACTIVE annunciator is on steady. If the ACTIVE annunciator is not on steady, do NOT continue the approach.

Approach Transition

Approach Transition operation begins again when you cross the MAP. Decide whether you are going to land or perform a missed approach. If you are performing a missed approach procedure, press the OBS/HOLD annunciator to enable waypoint sequencing. The CDI will scale back to 1.0 nm.

Waypoint Arrival Alert

A standard Waypoint Arrival Alert message is generated when you reach each approach waypoint. Press the MSG button to view and acknowledge the message. Press MSG again to return to the previous display. The Waypoint Alert indicates that you are close (approximately 1 nm for every 100 nm/h or about 36 seconds) to the destination waypoint.
