Garmin GPS 150 - Manual (Page 23)

The following information can be displayed in the ETE field:
• ETA – Estimated Time of Arrival (at the ‘active to’ waypoint).
• ETE – Estimated Time Enroute (to the ‘active to’ waypoint).
• trk – Track, or the direction of movement relative to the ground.
• vn –
Vertical Navigation, or VNAV. If VNAV has been activated (see
page 17), this field indicates either the elapsed time before the
VNAV maneuver is to begin, or the VNAV altitude if a maneuver
is in progress. The VNAV altitude displayed is the suggested alti-
tude you should be flying in order to complete the maneuver.
To change any of the fields on the CDI page to display other information:
1. Press
C
, if necessary, to activate the cursor.
2. Rotate
O
until the field you would like to change is highlighted.
3. Rotate
K
until the field displays the desired information.
4. Use
O
to highlight another field, or
C
to complete.
When navigating towards a destination, it is sometimes desirable to intercept that
waypoint on a certain radial. The OBS (Omni-directional Bearing Select, or inbound
course select) allows the pilot to set the desired inbound course to the destination
waypoint. This is similar to selecting the desired course on a VOR indicator.
To set the OBS (You must have an ‘active to’ waypoint):
1. Highlight the steer field and select ‘obs’ as shown above.
2. Rotate
O
until the number field to the right of ‘obs:’ is highlighted.
3. Use
K
and
O
to enter the OBS course (0-359º).
4. Press
E
to accept.
The CDI will guide you to intercept the desired radial upon reaching the waypoint.
