Altitude Buffer - Garmin GPS 150 Pilot's Manual

The GPS 150 will allow you turn the SUA alert messages on or off. This will not
affect the airspace being listed on the SUA Alert page, it will simply turn off the alert
messages when you are approaching or near an SUA. You can turn off alerts for the
following airspaces:
class B / cta : ICAO control area
class C / tma : ICAO Terminal Control Area
Other areas include alert, caution, danger, training, unspecified, unknown and
warning airspaces.
The 'alt' field is an altitude buffer which may be set so that SUA alerts do not
appear if you are a given vertical distance above or below an SUA.
For example, if the buffer is set at 500 feet, and you are at least 500 vertical feet
away from an SUA and NOT projected to enter it, then you will not be notified with
an SUA alert message.
