The "offset" is (going from memory here) configuring the system through the AP on your phone that tells the unit where on the airplane it is located relative to the longitudinal axis of the aircraft and relative to the nose of the aircraft. So on my airplane the SkyBeacon being on the wingtip was about 18 feet offset from the longitudinal axis and about 8 feet aft of the nose. I do not have the exact numbers of what I used but hopefully you get the idea. I guess the beacon accounts for that offset when transmitting it's position. Seems a little crazy to me that that level of accuracy is needed. I figure if the beacon is transmitting from anywhere attached to the airplane, that ought to do it terms of accuracy but what I know?
It is very easy to do so I simply did what I was told via the instructions provided by uAvionix.
If that step was skipped, it is difficult for me to imagine any negative consequence but again, what do I know?
