E-Perform INS (Inertial Navigation System) alignment
Note: You can use normal alignment (about 8 minutes) or stored heading alignment (about 2 minutes), the latter is faster, but the accumulated drift error is faster.
Set the EGI selector to ALIGN NORM (alignment standard) to complete the normal alignment. The aircraft coordinates need to be confirmed. When the INS calibration status reaches "6", the calibration is complete. The heading alignment stored in
STORED HEADING is done through the EGI selector set to align with ALIGN STOR HDG, because the aircraft coordinates have been entered into the system, so no confirmation is required. When the INS calibration status reaches "10", the calibration is complete.
39. Set the EGI (embedded GPS/inertial navigation system) selector switch to ALIGN NORM (normal alignment) or STOR HDG (stored heading alignment). This will perform an inertial navigation system calibration. It takes about 8 minutes for
to be fully aligned for normal alignment, and about 2 minutes for stored heading alignment.
40. INS (Inertial Navigation System) alignment status is available on the DED (Data Input Display) INS page. When INS calibration is performed, this page will be automatically selected.
41. Enter and confirm the aircraft coordinates used for INS inertial navigation alignment.
a) Important note: within two minutes after starting the calibration, the latitude and longitude coordinates of the aircraft must be entered or confirmed on the INS DED page. Failure to complete this operation within 2 minutes will result in a decrease in the alignment performance of the inertial navigation system.
b) Check the aircraft coordinates through the F10 map.
c) The "*" symbol next to LAT indicates that the LATITUDE latitude field is selected. Confirm that the entered coordinates match the aircraft coordinates. Usually, these coordinates should be matched and no correction is required.
d) Press the "ENTR" button on the ICP (Integrated Control Panel) to enter/confirm the LATITUDE latitude coordinates.
e) Press DCS (Data Control Switch, also known as "Dobber") to select the LNG (longitude) field.
f) The "*" symbol next to LNG indicates that the LATITUDE longitude field has been selected. Confirm that the entered coordinates match the aircraft coordinates. Under normal circumstances, these coordinates should match and do not need to be corrected.
g) Press the "ENTR" button on the ICP (Integrated Control Panel) to input/confirm the LATITUDE longitude coordinates.
42. For normal alignment: When the alignment status indicator reaches "6 RDY", the INS alignment is completed.
For stored heading alignment: when the alignment status indicator reaches "10 RDY", the INS alignment is completed.
43. When the INS calibration is completed, set the EGI (Embedded GPS/Inertial Navigation System) selector switch to NAV (Navigation).
