Compass calibration
CAUTION:
COMPASS CALIBRATION OF THE SKYVIEW SYSTEM HAS TO BE
PERFORMED IN THE AREA SPECIFICALLY DESIGNATED FOR THESE
ACTIVITIES. (WITHOUT ANY METAL CONSTRUCTIONS, ELECTRICAL
WIRINGS, NATURAL IRON ORE DEPOSITS IN VICINITY OF THE AREA,
ETC.). FOR EXAMPLE COMPENSATING CIRCLE ON THE AIRPORT.
DURING THE COMPASS CALIBRATION PROCEDURE, ENGINE HAS TO
BE RUNNING AND ALL ELECTRICAL DEVICES ON BOARD HAVE TO BE
TURNED ON.
1. Warm up the SkyView system for a 5 min period.
2. With a cursor, select an option COMPASS CALIBRATION.
3. Functionality check of SV-GPS-250 – all information about the magnetic intensity,
magnetic inclination, magnetic declination, information about the location, time and date
have to be displayed in green.
4. Place the aircraft precisely to the magnetic north direction and lock it against any
movement.
5. Press button 4 NORTH and wait for the system to compensate the data.
6. Place the aircraft precisely to the magnetic east direction and lock it against any
movement.
7. Press button 5 EAST and wait for the system to compensate the data.
8. Place the aircraft precisely to the magnetic south direction and lock it against any
movement.
9. Press button 6 SOUTH and wait for the system to compensate the data.
10. Place the aircraft precisely to the magnetic west direction and lock it against any
movement.
11. Press button 7 WEST and wait for the system to compensate the data.
12. Press button 8 SAVE.
13. Press button 8 FINISH.
OAT offset
1. Find out the value for the correction of the temperature (in comparison with appropriate
calibrated thermometer).
2. With a cursor, select an option OAT OFFSET.
3. Set the proper value for a correct temperature indication (+/-).
4. Press button 8 ACCEPT.
Zero pressure airspeed calibration
NOTE:
This calibration can improve the accuracy of indication at very low airspeeds.
