There is likely a lot more inaccuracy in the "satellite" photo position on the map than in the aircraft GPS position.
A good idea to pick a "calibration point" on the satellite photo as the first waypoint, eg directly above the chimney, then compare the position of the chimney looking directly down on the live view with where it is on the satellite photo, if you can see that it is 10m out then you know to abort and adjust the waypoints. That doesn't tell you if it is the GPS or the map that is wrong, but it does give some confidence that there wont be a crash, with 2 calibration points you can also check the angle of the photo against reality, but that is unlikely to be far out. |
