GINA Operating Characteristics
(b) Coordinates on ACFT DATA page
commence being computed with pure
GPS data, provided GPS is functional
NOTE: GPS must be selected (boxed)
on the ADI display page; otherwise,
coordinates will be blank.
(c) Compare INS coordinates on the
ACFT page with GPS coordinates
(d) Check accuracy of present position
coordinates
(7) Avoid flying in IMC condition if at all
possible
(8) Land as soon as practical
(9) Removed MFD display data will be restored
if problem corrects
PROGRESS CHECK
Question 8 -- 1.7.7.6.1
What does the Kalman filter, filter?
ANSWER: It is not a filter in the traditional sense of the word.
Simply put, the Kalman filter provides a set of weights and
balances. It allows the GINA to combine computerized data
from different sources, emphasizing and minimizing appropriate
values, so the derived solution is the best solution.
Question 9 -- 1.7.7.6.1
When is WYPT-0 used to align the system?
ANSWER: Only when specifically invoked by cycling GINA
PWR, selecting RST, changing a WYPT-0 coordinate, or
initiating a GINA IBIT.
