I know you werent asking this, per say....but since it was mentioned.
Pythagoreas...figured it out...that Hypotenuse thing you learned in school. Altitude and Range and Speed all figure in. When I bomb Gvs or hangers. Usually its 35 degree above 300mph drop when I see icon. Dont miss much
Hangers you can come in Higher/Steeper then again my set up, is to fire Rockets AND Bombs same pass! Level bombing will be just simple Pythagorean Geometry...once speed is stable. Most guys I see doing this are just CARPET Bombing Towns or possible GVS...not much skill involved IMO
If you want to kill GVS practice dive bombing OffLine. You can enable the Dive Bomb Precision aid.
