Re: Norden bombsight
Now referring to the ballistics video. The distance between the predicted impact point and the whole range point, trail distance, is given by the formula H Tan Lamda where lamda is the trail angle. The video then mentioned wind effect. Cross trail is given by the formula H Tan L Sin delta and the trail distance becomes H Tan L Cos d where d is the drift angle.
