Would it be possible to add a control for the "abeam terrain clearance function" to the enroute features display and allow the minimum to be zero. The purpose of this is to show the terrain profile directly below the flightpath which would be very useful in determining a safe altitude to fly along a valley.

Also, could there be an option to show a shaded area on the the chart between the route line and any terrain that is closer than what is set for abeam terrain clearance(ABT). When ABT is set to your aircraft's turn radius plus a safety margin this would highlight any points where a valley is too narrow to make a 180 deg turn.
