the GPS 155XL. Check the I/O settings and/or
the serializer installation. If enough satellites are
available for a 3D position fix, no pilot action is

sent. If only a 2D fix is possible, the pilot
should enter an altitude within 1,000 feet of
the current indicated altitude.

position. Check the switch/installation.
Approach deleted

selected, or RAIM is not predicted to be available
from FAF to MAP. Do not descend to the FAF.
Arm approach mode - Approach navigation is available. Set the GPS
APR switch to the ARM position.
