No. I always receive cal nag because i am on terrible steel ibeams concrete parking structure. So powerdown nag unfulfilled, drive to manoa park, powerup, last "unfulfilled nag" gone, none requested at manoa park. If i purposely place craft on a steel grating coverplate in manoa park, bingo, cal nag. That shows you iron elicits cal
You obviously didn’t understand what I was referring to. If your compass NEEDS calibration if you compass values are not correct then no matter where you go, it will still need calibration.
If you have magnetic interference which is what you referring to, of course if you move away from the interference it will be gone. I would never advise anyone to calibrate in an area of magnetic interference, below is my preflight procedure.
TipTo Help Avoid compass interference and crash.
1/ Never calibrate Compass unless prompted to.
2/ start AC leave until you receive enough gps lock ,
3/ if you get Compass interference turn off AC and move to another location,
without interference.
4/ In bottom left hand corner on your map you will see small red triangle, check to make sure that this triangle is pointing in the same direction (heading) as your AC, this will show good compass on the ground.
Raise AC to height of 8ft
Hover for 20 seconds
Fly forward 2ft
Backward 2ft
Left 2ft
Right 2ft
Up 2ft
Down 2ft
Yaw left
Yaw right
Each time returning to hover position
If you have a good horizontal each time, you will then know you have good GPS good IMU and good Compass, and your ready to fly.
This exercise takes less than 2 minutes and is worthwhile doing before every flight, |
