"If this was a steady sight picture and the pipper had stayed steady for one second already and let’s say instead of the targets left displacement, you would be in the same plane of motion, so the target would be along your gun centreline.

If you now pressed the trigger , would you expect to score hits? Or is the pipper too far aft on the Center of the target aircraft  body?Would it be considered a valid shot?"

In short yes if you have the steady tracking.... especially against something as massive as a Tomcat.

Having "The line" in the targets plane of motion is strictly speaking a sight handling thing, By getting the line in the targets plane of motion then you can predict to a certain extent pipper drift, and allows smoother control. If however you can achieve 1.2 X time of flight steady tracking anywhere on the aircraft then it would be considered a valid gun shot. However maintaining the pipper on the target without having the line in the targets plane of motion is going to be a lot harder. As the G increases (typical of a guns tracking pass with reducing range) then the displacement of the line from the firers plane of symmetry (Gunsight centreline) will reduce. so as the pass continues with increasing G then you again need to smoooooothly increase roll in the direction of the turn. So a guns tracking pass is a very finely balanced 'tapping your head and rubbing your tummy" type of thing. The F14 shot was at fairly low G ... hence the displacement from the firers gunsight centrline. So in general terms how far the Sight line is displaced from the gunsight centreline is a direct indication of G.

All this discussion is in relation to LCOS distributed sights.

Image below is a guns tracking pass with ball ammo on a DART towed by a RMAF F5E in a left hand turn. (DART is pretty small ... a lot smaller than the 30ft banner we usually used)  These are two successive frames of a radar locked tracking pass at 5.4hm (so a long range shot). If you look closely can see puffs of smoke coming from the DART from ball impacts. On this sortie we (2 of us) ended up shooting the thing off the cable.

And one more image because its a beauty .... a Slow crossing rate snapshot

Hi Ivan,

thanks a lot and sorry for my late reply. For me it isn't really working.I tried replicating your picture with and F-14 as target and the pipper on its center mass.The gunsight seems to compute insufficient lead still. I will wait for the upcoming flight control update Fausete mentioned, to see if it helps getting more the nose more stable for steadier pipper control , right now the pitch still seems to want to oscillate slightly , for me at least.

After that and I will probably file a bug report for the gunsight if there is still no improvement. Thanks again for all your detailed answers with those interesting pictures here!

Kind regards,

Snappy

Found this image on the net Guns pass F1CG v F16. Just attached the line and GBL and centreline lines. Illustrates the Lead and Line quite well in the F1. Gun bore line is the centre of the Range scale index marker. Range 4.2hm.

Hey,

yes I have that Image too  . It’s a nice one! The Problem is currently in the Aerges F1 , if you fired with that sight picture, the rounds would miss the target and pass behind it

I agree that the gunsight currently does not provide enough lead even if the target is turning at a meagre 2 or 3 g. The bullets always fly behind the target, until you get so close that the error does not matter any more.
