I just did some segments on a 767-300 ER and noticed that the "Moving Map" function on Delta's AVOD doesn't show a map whatsoever. Not at all in the various times I switched to it and watched it for a few minutes at a time. All "Moving Map" shows is the usual "time at origin", "time at destination", "remaining flight time", "altitude" statistics, toggling between multiple languages (which is also stupid because the passenger has selected a preferred language when the screen is first turned on). Why did Delta take away this feature? "Security" concerns?
