Spitfire gunsight tutorial

it’s a video on aiming with the spit gunsight

it’s nice seeing again the lead compared to deflection angle to hit a 109. (probably we should keep a print close to our monitors)

but what i liked more is thinking of guns path somehow as trunked cones due to dispersion…
with the ending result of overlapping cones in the harmonized zones…

PS probably they should be curved cones due to gravity effect!

Cheers that was interesting.

so the convergence was about 250 yards (228 meters) for all the guns?

If i remember correctly at the beginning 330 yards was the standard, then they put it much closer! And then squadrons and single pilots were allowed to use personal settings like harmonization etc…

Topsy and other history experts correct me if i’m wrong…
