Map/Plan page drops approachs
Our fleet of 139's has a problem with the Honeywell Primus Epic dropping the displayed information for certain types of approaches. It appears to be mainly North/South approaches: (ILS/GPS types). You can call up the approach and it will momentarily display the approach then the screen goes blank. Honeywell is aware of this problem, but says we are the only operator with this problem. Anyone else have this problem? They tell us that Phase 5 will fix the problem. Revert back to executing the approach as I have always done it. The information in the MCDU/FMS is correct, ( I wonder if it will be incorrect on some approach), just drops the planview.
