During the next EFIS software upgrade it would be nice to have other use selectable options besides waypoint ETE. ETA (next waypoint or destination) in hours & minutes and TOT in hours/minutes/seconds. The TOT would be extremely helpful trying to make an exact timing for a national anthem flyover. This TOT function in hours/minutes/seconds is already incorporated into the Garmin Aera 660/760 portable GPS so I can’t imagine it would be that hard to implement into the already very capable AFS EFIS line.
