I struggle to understand why you wouldn't want to display a servicable navaid, it's just another level of situational awareness isn't it?
Why indeed, CM, and I think the real reason some folks don't like 'em is....they have absolutely no idea how to use them effectively.
Look at the very nasty Cali Colombia American Airlines accident some years ago.
These prats were cleared directly toward an airfield beacon, dialed up something totally opposite in their FMS, and promply flew right into a hill, killing everyone.
The captain had 12,000 hours...twelve thousand friggin' hours, and he couldn't be bothered to dial up the airfield beacon and proceed accordingly.
More than likely....didn't know how.
About time these turkeys were locked in a sim (without their multi-thousand dollar salaries) until they find out.
