I think people generally underestimate the complexity involved with modern avionics. In the case of the F-22, 90 % of its 1.7 million lines of code is associated with its sensors and radar There is a big divide between AESA and older radars. The strength of the F-35 is not in its stealth but in its sensors - the type that requires 8 million lines of code. Even the Typhoon tranche 1 needed 1.5 million lines of code.

I personally understand that principle, but I question the nature in which the practice of more complex avionics may prolong or complicate things such as integration of new systems.
The degree to which a system is designed to be open architecture, modular, and/or the way in which different systems may have been designed or implemented to mitigate or minimize mutual interference are confounding factors.

For example with JF-17's Indra EW pod, it is likely that whatever AESA they end up choosing will have the requirement to be compatible with the pod itself (there's two Chinese AESAs and one Italian AESA in the running from memory).
Additional, systems such as SABR which are offered as off the shelf AESA upgrades for fighters equipped with legacy radars, where those AESAs can replace legacy radars with minimal back end processing changes.

Really? ;)

If you follow certain members here or in other forums you get the impression, designing an aircraft and bringing it operational status is just some plug & play or installing a new app on your mobile!:rolleyes:

A modern car requires a 100 million lines of code as of 2014. Actually I find this idea frightening. This is 2019 now.

Tell me something more meaningful like how many million lines of code the J-20 has. I don't get it why people keep invoking straw man answers.

I don't get it why people think that 8 million lines of code is somewhat of a boast. Today, one should be asking what kind of thing runs with only 8 million lines of code.

… because some of us still deal in facts and not fantasies or fallacies.

You mean 100 million lines of code for a modern car is not a fact? Maybe reality needs to go knock knock on your fantasy about IT. Many games alone has tons of code. Skyrim for example is said to have over 46 million; GTA V is said to have over 100 million.

You still don't get what a straw man fallacy argument means. It is beyond my capability to help you then.

What exactly is your point then? Ignoring the back and forth. Yes so some people here (not everyone) may underestimate how much work there is going into integrating a radar. 100% agree. And what though? What are the consequences of some people online not understanding the complexities? Are the folks working on integrating a certain radar with a certain fighter not capable of producing n lines of code? No? Okay so if they are, then what is your point? If they are not, please explain why not.
