Kaan has not flown with indigenous flight controller etc.

Same story as Hurjet. They promote it as fully indigenous until the promotion period ends and then they tell "well actually not all components".

It doesnt matter does it?
First flight 13 minutes,that was the important part,nothing else.
It flew!
If block 10 is still not indigenous(i dont mind MB),then we can be angry.

should be next week, dont count on me tho
I will be looking at those massive elevators at take off. They will(or already have) tweak the gains of the control algorithm so that it won't go in a loop of overshooting the reference point and overcorrecting.

Can you summarize it briefly? What did they say about the first flight?

They are talking postive about the fist flight and landing onyle thing they are little bit jocking about the rear wing going up and down.

Based on what I've seen, it needs no tweaking.

Even in its 1st iteration, KAAN is such an agile aircraft that, even the slightest pull up on the stick was enough to lift the nose up with haste.

Barbaros komutanım had to exert extra effort to make a smooth takeoff and not to straight up launch into space next to the ISS.

It's not normal to have your elevators oscillating with so large displacements. It's clearly overshooting and that is perfectly normal for the first flight. You cannot know every parameter of your aircraft's model to feed the control algorithm before the first flight. You have to make some assumptions. Now that you have the data, you no longer have to assume. You just change the weights.

Best to have what you don't need, than need what you don't have.

I'm very late to the party... but better late than never! Congrats to all the Turkish friends for the magnificient achievement by your countrymen.

Big respect to all the bright minds of Turkiye. My perception of Turkiye 8 years ago was different to what I thought 4 years ago, and what I've though 4 years ago were very different from what I think now! It's such a fast development.

Though, also remember that there still lies great mountains to climb, and the first flight of GTU-0 was only the first hill overcome. The software and avionics centric nature of 5th gen fighters mean that lots of critical technologies and their integration into single system is still to be proven. That also means, don't feel let down if there are any hardships or news of delays, since as a military fan the best you could do for the engineers on field are to give support for their hard work. Of course, don't forget pay your taxes, too ;)

I'm quite hesitant to make these comments right after the positive words, but I should say what I should.

Than Brits begged France to give 'codes' to engage Exocet missile. After Brit convinced France to gave the codes, they could engage the missiles.
What is blud talking about? "Codes"? What codes? The reason RN had difficulties with Exocet in the beginning of the war was down to the problem with Type 42's combat systems and EMI problems, not some "Exocet code" bull crap.

Seriously, I sometikes wonder if this forum needs a sanity check.

Except Israeli version, all uses the same hardware for EW suite. that is BAE system's AN/ASQ-239 baracuda. (I am not denying the significant difference in software though)
There's quite a huge number of members who are very inclined to believing these wild theories of conspiracies, you'll not find much success in correcring them.

Also, that "significant difference" in SW is mostly down to which OFPs are onboard the ICP, which is also not something fundamental as an aircraft of different specification.

"6G GCAP" bold claims. The last time I checked there were problems between GCAP partners, many supposed 6G features were trimmed down to realistic levels (aerodynamic design is similar to KAAN) and the cost per unit is estimated at 300+ million. There is no willingness from the UK to make KSA a part of the project. We will see the big picture better once the project amounts to something until then it is all on paper.
GCAP partenrs aren't having much problems negotiating, at least as of yet, and compared to any other recent high profile international programs, it's running remarkably smoothly. UK is already engaged in designing and manufacturing of Tempest TD aircraft, and is willing to cooperate with partner nations in this regard.

There are ongoing joint programs between Japan and UK, and Leonardo exists as a Anglo-Italian effort, which effectively bridges the tri-nation and their technological exchange. They are all very engaged to the program.

Further, mind clarifying what the alleged "trim down" is? How could they trim down developmental goals when project definition itself isn't even complete? Also, current GCAP concept clearly has a more advanced aerodynamic design compared to Kaan or F-22 with Lambda wings coupled with Pelikan wings.

There are also no concrete cost estimates since like I've said it's not even dome with preliminary phase of development. If anything, the ongoing R&D programs indicates that the GCAP is aiming to become a very ambitious aircraft interms of its features and capabilities.

Lastly, the UK and Italy are both very willing to accept KSA as a partner. It's Japan who's strongly opposed to such inclusion.

My theory, BİLGEM piggybacked FCS off other computers like the Central Management Computer, since they share a common architecture. The other computers don't do a lot right now, so it makes sense. Therefore, I believe the systems are in-house, but a full independent computer isn't installed for flight controls. Hence BİLGEM isn't confident announcing it's "used on the first flight", but TÜBİTAK management probably doesn't mind not making this distinction.
One thing's clear, and that's unless some other party was a deep part of the design work from the start, the flight control model would've and must've been developed by TAI in-house. As for Hurjet that seems to have been outsourced to an Italian partner, but that's not a big deal either, so as long as indigenous program is running in parallel.

Even if GTU-0 uses foreign flight control computer as of current, the implementation of flight control software itself must've been done by TAI for above reasons. Maybe just maybe, BAE could've helped them out, presuming that the flgoht control system for GTU-0 is completely outsources, but regardless, I don't see much problem with incremental development considering the nature of GTU-0.

There are still 2 years of time compared to the original plan to get the avionics ready.
