BY the way, '2017' seems to have the older - regular J-11B/BS & J-10B style - HUD again.

Also, a key thing to note is that in the picture you are referring to, 2017 and 2011 are set at slightly different angles relative to the camera, therefore the HUD of 2011 is seen completely side on (therefore looks thinner) while 2017's HUD is seen from a slight angle to it looks thicker.

That is why true accurate comparison of 2017's HUD with any other J-20 prototype (until we get more high quality pictures) will be dependent on having other J-20 pictures showing the aircraft at the same angle.... and that is essentially the cockpit comparison pic I posted in post 951. Unfortunately that pic of 2016 is not very high quality either, but it does give a far better view of what the HUD is like from the same angle.
Personally I am highly confident hat the 2017's HUD is the same model as that of previous 201X prototypes, but it may possibly feature slight thickening of its frame especially at its superior portion. I am also highly confident that 2017 definitely is not using the same type of HUD as J-11B/J-10B, because that particular HUD model is far significantly thicker and also features additional components compared to what we see on 2017.
If 2017 was using J-11B/J-10B's HUD model, it would be obvious even in low quality pictures and not a subject of dispute.
Of course it also doesn't make sense for 2017 to suddenly revert back to an older type of HUD when they've been using the new kind for six successive prototypes without issue... OTOH it makes a lot of sense for them to add a small modification to their current new type of HUD in preemption for LRIP.

Ok here's a J20 summary of all 8 units

Maiden flight as follows

2001 on 11/01/2011
2002#2004 on 16/05/2012

2011 on 01/03/2014
2012 on 26/07/2014
2013 on 29/11/2014
2015 on 19/12/2014
2016 on 18/09/2015
2017 on 24/11/2015

That's 1 x J20 in 2011
1 x J20 in 2012
4 x J20 in 2014
2 x J20 in 2015

2013 low year and 2014 very big year but they went from demo to prototype

The new geometry of the canopy is somewhat reminiscent of the F-35's... the previous prototypes were more reminiscent of F-22... I wonder what kind of design considerations made both CAC and Lockheed change to the newer geometry or if it just happened to be incidental.

To me the F-35 canopy seems a bit taller but shorter in length in comparison to the J-20 new canopy.

Well obviously they're not identical, but I think they are similar in a number of ways when one is considering the few examples of one piece canopies for true 5th generation fighters.

I feel weird with this photo. I don't think that the plane is ready to fly, looking at those women and people around the aircraft. It is a kind of ceremonial event. Then why there is a pilot inside the cockpit? It feel like the aircraft is ready to fly.

The women with the flowers are probably preparing for the ceremony... and the aircraft looks like it is ready to fly because it is ready to fly.
Maybe the ceremony would occur immediately after the take off of the aircraft, or maybe it would occur during the flight of the aircraft, or maybe after.

There's no reason to think the pilot would be the one to receive the flowers or be the centre of the ceremony.
In fact if this ceremony really is to celebrate the end of the J-20 prototype production before starting LRIP, then the project managers and department heads would be the focus.
