Turn the GPS 150 off in preparation for a signal acquisition test.
The following tests assume that the aircraft is outside the hangar facility and well away
from buildings or other obstructions that might interfere with satellite signal
reception. With power applied to the aviation rack, turn the GPS 150 on. The Self Test
Page will be displayed followed by the Data Base Page. Upon approval of the Data Base
Page, the Satellite Status Page will be displayed. If unable to acquire satellites,
relocate the aircraft away from obstructions which might be shading reception. If the
situation does not improve, check the antenna installation.
Once GPS position information is available, use the DIRECT key to activate the
navigation function to a nearby NAVAID, intersection, or airport. Ensure the ARGUS,
STORMSCOPE, EFIS, fuel management system or other mapping device is receiving
data from the GPS 150 and is functioning properly (see Chapter 5 of the GPS 150 Pilot's
Guide for more information on the Direct function).
