How do you switch it into SUSPEND mode ?

I can only speak to the Garmin 400/500 series. SUSPEND is built into
the nav database by Garmin for an approach. At a minimum, there is
SUSPEND for the missed approach point. It is cleared by hitting the OBS
button.

Other times SUSPEND occurs:

1. At a course reversal hold, SUSPEND lasts for one circuit in the hold.

2. At a published missed approach hold, SUSPEND lasts indefinately until
cancelled.

3. SUSPEND can occur more than once for a missed approach, such as where
an altitude has to be achieved before a turn can be made (example KJAC
ILS 19)


Kyprianos asked how to switch *into* "suspend" mode, not *out* of it.
I don't have access to a KLN94, so I can't answer his question, either.
But on my CNX80, the "SUSP" button toggles into and out of the "Suspend" mode.

The pilot cannot switch a Garmin 400/500 series into suspend. He can
only invoke OBS mode, which is similar to, but not identical to, suspend.



Furthermore, the CNX80/GNS480 does not automatically "suspend" at the MAP.
If the aircraft doesn't land, the missed approach continues to sequence.


That sounds dicey if you are using autopilot in NAV mode, and there is a
turn required before you might be ready.
