cant put plane in a route

[blumage]

I want to create a route with a
Distance: 6,922nm   
with my lockheed 1649A Starliner but when i go to create a route there is no plane that i can  choose. The plane  lies untouched with 24 hrs and no routes. I also tried creating routes to another destination but the planes shows in that one. I also checked before with the research a route tool and that plane is one of the ones listed that can fly on that route.HKG-SFO to be exact. I bought the gate and spent about 300k on research fees and i cant put that plane on that route.
ID 5228 plane im trying to put is 29360. Thanks in advance.

At a speed of 287NM plus 0.39 hours for turn time, the most you can reach in 24H is something like 3,332NM.

Well they shouldnt put it in the research route if it cant fly there in the end, you have a range of 7000+ then u cant fly that far in the end. What's the point? It made me loose money

Research route checks for range capable aircraft. A change will probably be added in the multiworlds release.
