Hello

 

I have a problem with FMS in JS 4100   the FMS  WILL NOT OPEN  when on button pushed.

Could someone send suggestions about   what might cause the problem I simultaneusly use  GNS 350

Plane works perfectly  otherwise.

 

Thanks in advance

George

 

 

 

Could someone send suggestions about  what might cause the problem?

 

Is the aircraft properly powered, either on the GPU or with the engines on with GENs on?

That shouldn't cause any issues, but I can't say that for certain.  I find the practice wholly unrealistic and unnecessary, as the FMC will do what the GPS does and more, so you wouldn't be losing anything by taking that out.
