(b) Ground alignment, GINA align
complete takes approximately
3 minutes after present position
initialization
(c) In-flight alignment, GINA align
complete takes between 5 and 15
minutes, 90-degree heading change 1
minute apart after altitude is valid will
reduce alignment time
(d) Ship board alignment, altitudes
available in approximately 20 seconds
and position and heading are available
in approximately 8 minutes
d.
Subsystem interfaces: provides flight data
information to the DEU readouts on ADI, HSI
and HUD displays
(1) Power
(a) 28 VDC essential services bus
(b) 115 VAC essential services bus
NOTE: GINA is operational upon loss
of the generator.
(2) Also exchanges information with YDC,
ADRS, and VOR/ILS/MB

Summary:
The GINA three ring laser gyros and accelerometers
provide stable and accurate information of
acceleration, velocity, position, heading (true and
magnetic), digital and analog attitude (roll, pitch, and
heading), attitude rates and time. The GINA flexible
initialization and alignments for ground, in-flight and
on-board ship provide the best accuracy for flight
profiles. The selection of modes for GINA operation
