INSTRUCTOR NOTES
An in-flight alignment requires a four (4) GPS satellite lock-on.
Also, in-flight alignments are automatically initiated and require
no additional action, unless GINA is not responding.
Whenever an IFA is commenced, the aircraft should be in
straight and level and unaccelerated flight.
1.
IFA should be initiated following takeoff in DGRO
mode by selecting RST on the ACFT DATA page,
one (1) minute after a position appears on ACFT
display page
NOTE: Waiting one (1) minute after position
information appears, prevents losing attitude
information when RST is selected.

IFA should be automatically initiated following an
interruption of GINA power, etc., causing a platform
or heading problem or lost/incorrect symbology
