OK. Well it is the CV-340 that is the cause for the warning. I suppose it would have made more sense if the warning had said "no payload restrictions or runway limitations for this type," or writing the offending type in red. Prompting a warning and having "no payload or runway limits" next to the type, looks like, the aircraft can't carry a payload or is exceeding the runway limits. I had scheduled routes longer then these 2, prior to posting but it was not until I leased a CV-340 that this warning comes up. Perhaps you can understand why I thought it was a bug.
