Any F-16s they might get over the next five years are going to have avionics vastly inferrior to the Russian Su-35's IRBIS-E phased array radar.
If a Ukraine-piloted F-16 fighter group is ever deployed (I have my doubts that will actually come to pass), they better hope to not run into any Russian Su-35s. They will be down before they're even aware the Russians are in the air.
NATO countries will supply the pilots just as did Russia in 1967 for the Arab MIGs
No NATO pilot would volunteer for Thant suicide mission. NATO pilots are used to bombing defenseless unarmed women and children and civilians in third world impoverished countries with no militaries, no air forces , no air defense systems.
It would be a slaughter and very bad optics. Like our outdated military equipment in Ukraine now
