GINA Operating Characteristics
a.
Three (3) sigma deviation
(1) Three sigma: Three (3) times (300%)
normal deviation expected for position and
velocity data entering Kalman filter
(2) Three (3) sigma deviation has persisted for
20-24 seconds
(3) Selected display symbology is removed
from MFD/HUD
(a) Velocity vectors (from HUD) change to
waterline symbol
(i)
True
(ii) Ghost
(b) Ground speed (from both ADI and
HUD)
(c) Digital vertical velocity (from HUD)
(d) VSI (from ADI)
(e) Wind/velocity (from HSI)
(f)
TACAN, WYPT, WO/S estimated time
of arrival (ETA) data
(4) BARO altitude on the HUD becomes
unfiltered
NOTE: BARO altitude may fluctuate when
unfiltered
(5) AVBIT advisory generated on all MFDs
