same warning here (FL410)

moreover atc wanted me to cruise at FL460 while my altitude knob max at 450
is it ok irl to receive these ifr plans?

Service ceiling of the CJ4 is 45000 so you should never go higher.

In reality, RVSM airspace also has increased separation between the levels when that high. I believe you can set your cruise level yourself in the 2024 tablet, or simply request 1000 lower from ATC to get FL450
