You will now notice that the vertical speed field has been calculated. If you desire

a faster climb or descent, you may enter that value now. 

7. Use 

K

and 

O

to enter the new desired vertical speed, or press 

E

to accept the 

calculated value.

If you enter a greater value, the GPS 155 will display the elapsed time before the

maneuver is to begin. When the countdown reaches 15 seconds, you will be
informed with the message ‘Start altitude chng’. The VNAV function will automatical-
ly be cancelled if the active route is changed in any way. In this case, you will be
informed with a ‘VNAV cancelled’ message. 

The GPS 155 will allow you to create up to nine 

checklists

with 30 items each to

remind you of repetitive tasks that can be called up at any time for review. The check-
list feature is useful for creating pre-flight checklists, landing checklists, emergency
procedures, etc. Each name or function can have up to 16 characters.

To create or edit a checklist:

1. Press 

C

and rotate 

O

to highlight ‘Chklist?’. Press 

E

.

2. Use 

O

to highlight the checklist number you would like to create or edit.

If there are no checklists, you must select the first checklist field. Press 

E

.

3. Use 

K

and 

O

to enter the title of the checklist. Press
