The uncertainty in the wind drift angle is usually a lot more than that. Huh? What does the wind have to do with VOR's. If the needle is centered, you're within the tolerance of the VOR. The tolerance is primarily 4-6 degrees. This keeps you inside the airway at moderate distances from the VORs. The uncertainty in the wind correction angle is greater than the total error in a VOR radial. So you plan the flight given the winds aloft forcast, crank in a wind correction angle, and come up with a heading. The heading you wind up flying to keep the needle centered will seldom be the heading on your planning sheet. That's all I'm saying. -- Jim Pennino Remove .spam.sux to reply. |
