Prepare Gyro Compass for Longer Time Setting Out of
Operation
About this task
Note
The procedure for longer time setting out of operation can only be performed by Raytheon
Anschütz Service and must be used if the Standard 22 NX is set out of operation for more
than 3 months.

Manual Correction of Speed Error
The speed error cannot be calculated automatically, if speed and / or position are not
available. In this case an uncorrected heading information is output. However, the speed
error can also be calculated manually.
2.6.1
Correct Speed Error Manually
Procedure
1. Determine the latitude and the speed of the vessel.
2. Take the heading from the gyro compass.
3. Determine the correction value from the speed error table, see
.
4. Calculate the true heading.
Example
No.1
Latitude:
55°
Speed of the vessel:
16 kts
Gyro compass heading:
345°
Correction value:
- 1.7°
Calculation:
345° - 1.7° = 343.3°
True heading:
343.3°
No.2
Latitude:
55°
Speed of the vessel:
16 kts
Gyro compass heading:
223.7°
Correction value:
+ 1.3°
Calculation:
223.7° + 1.3° = 225°
True heading:
225°
