You're welcome! I thought about other people who had the same problem and were lost in the air. During night and raining you can't see anything 😉
Thank you very much for your information @hervesors it's great to have real information to simulate as real as it's possible.
ADA is correct with P3D, 80 NM
SAT is correct with P3D, 128 NM
BFR according to P3D is 50 NM
TBE is correct with P3D, 25 NM
Therefore, when I was flying the NDB range was not enough to cover the route. Since RNAV is replacing the navaids neither VOR nor NDB are needed anymore. Some exists as backup. The old routes were covered by VORs, which the range is better.
If it is of your interest I can share the route which uses NDBs as navaids.
Best regards!
