Purpose of the Dive Angle Markings?

I'm curious, what's the purpose of the dive angle markings on the canopy? Of course they tell you what your dive angle is when you're looking out your 3/9 line, but how is that useful? They don't tell you where on the canopy to put a target to achieve x-degree dive for bomb/rocket/gun runs, the attitude indicator already gives dive/climb angles, and there's also the specialty dive angle display for bombing on the dash.

You use your gunsight for aiming when divebombing. You use the dive angle indicators to fine tune to a specific angle for maximum accuracy. Exact same thing Stukas did in the 40s.

You can either dive at a 45-60 angle and hope for the best, or you can invert pull 90' and drop straight down. It is not CCIP bombing, much cruder and you'll miss as often as not, usually more, but it's how things worked in the 40s and 50s.

It's basically a hold over back up gauge. As yes, there are other systems that are more accurate available. That's why they quit using them.

It's just an extra reference to check angles.

This is a great old video by Bunyap, he talks about how it would be good to use with your peripheral vision (7:00 mark) if you could in sim. Have to try it and see if the Rift now gives you enough peripheral vision to see it when diving in.

Wouldn't fine-tuning your dive angle with the canopy markings then throw off your impact point, as your point of aim is going to shift as well?

I think left handed roll ins were not used with this. My idea is that they inverted and as soon as target touched 70-80 lines meeting on top of their heads where the lines supposedly continue, they pulled back inverted and focused more on the dash because they know they were established 90° or so to the target underneath. The trick was how they performed SEM given the sabres notorious diving behaviour.

I sometimes catch my own thrown bombs. Whats the max steep angle with the sabre?

got it. I throw them by having negative g´s
